Introduction

Blockchair API provides developers with access to data contained in 18 different blockchains. Unlike other APIs, Blockchair also supports numerous analytical queries like filtering, sorting, and aggregating blockchain data.

Here are some examples of what you can build using our API:

A wallet supporting multiple blockchains (request transaction, address, xpub data, and also broadcast transactions)
An analytical service showing some blockchain stats and visualizations
A service tracking the integrity of your or your customers' cold wallets
A solid academic research
Some fun stuff like finding the first Bitcoin block over 1 megabyte in size

For some tasks like extracting lots of blockchain data (e.g. all transactions over a 2 month period) it's better to use our Database dumps feature instead (see https://blockchair.com/dumps for documentation) — it's possible to download the entire database dumps in TSV format and insert the data onto your own database server (like Postgresql or whatever) to further analyze it.

Almost every API endpoint description is accompanied with an example visualization of the data on our website (https://blockchair.com), and it's also worth it to note that the website is working completely using our API (yes, even the data for charts is pulled from one of our endpoints, and it's fully customizable).

Blockchair cares about user privacy, we neither collect nor share with anyone your personal data rather than for statistical purposes. That includes using the API as well. Please refer to our Privacy policy: https://blockchair.com/privacy. Please also check out our Terms of service available here: https://blockchair.com/terms — by using our API, you are agreeing to these terms.

We have a public tracker for bugs, issues, and questions available on GitHub: https://github.com/Blockchair/Blockchair.Support/issues — please use it or contact us by any other means available.

Our API is free to try under some limitations, and we have a variety of premium plans. Please check out the information about the limits and plans.

Supported blockchains and second layers

As of today, our API supports 19 blockchains (17 mainnets and 2 testnets) divided into 9 groups:

Bitcoin-like blockchains (Bitcoin, Bitcoin Cash, Litecoin, Bitcoin SV, Dogecoin, Dash, Groestlcoin, Zcash, eCash, Bitcoin Testnet), also known as UTXO-based blockchains
Ethereum-like blockchains (Ethereum, Ethereum Goerli Testnet)
Ripple-like blockchains (Ripple)
Stellar-like blockchains (Stellar)
Monero-like blockchains (Monero)
Cardano-like blockchains (Cardano)
Mixin-like DAGs (Mixin) — technically, it's a DAG rather than a blockchain, but for the sake of unification it may be mentioned as a blockchain further in this documentation
Tezos-like blockchains (Tezos)
EOS-like blockchains (EOS)

Within a group, there's no or little difference between the set of available endpoints and their output.

Here's the list of available mainnets:

Blokchain	Group	API path prefix	Support status
Bitcoin	Bitcoin-like	`https://api.blockchair.com/bitcoin`	Full support
Bitcoin Cash	Bitcoin-like	`https://api.blockchair.com/bitcoin-cash`	Full support
Ethereum	Ethereum-like	`https://api.blockchair.com/ethereum`	Full support
Litecoin	Bitcoin-like	`https://api.blockchair.com/litecoin`	Full support
Bitcoin SV	Bitcoin-like	`https://api.blockchair.com/bitcoin-sv`	Full support
Dogecoin	Bitcoin-like	`https://api.blockchair.com/dogecoin`	Full support
Dash	Bitcoin-like	`https://api.blockchair.com/dash`	Full support
Ripple	Ripple-like	`https://api.blockchair.com/ripple`	Alpha mode, possible compatibility-breaking changes
Groestlcoin	Bitcoin-like	`https://api.blockchair.com/groestlcoin`	Full support at least till January 1st, 2021
Stellar	Stellar-like	`https://api.blockchair.com/stellar`	Alpha mode, possible compatibility-breaking changes
Monero	Monero-like	`https://api.blockchair.com/monero`	Alpha mode, possible compatibility-breaking changes
Cardano	Cardano-like	`https://api.blockchair.com/cardano`	Alpha mode, possible compatibility-breaking changes
Zcash	Bitcoin-like	`https://api.blockchair.com/zcash`	Full support
Mixin	Mixin-like	`https://api.blockchair.com/mixin`	Full support at least till April 24th, 2021
Tezos	Tezos-like	`https://api.blockchair.com/tezos`	Alpha mode, possible compatibility-breaking changes
EOS	EOS-like	`https://api.blockchair.com/eos`	Alpha mode, possible compatibility-breaking changes
eCash	Bitcoin-like	`https://api.blockchair.com/ecash`	Beta mode, possible instability. Also known as Bitcoin Cash ABC and Bitcoin ABC.

Please read our statement on the November 15th, 2020 Bitcoin Cash split: https://twitter.com/Blockchair/status/1324424632179576832. It is expected that Bitcoin ABC's hashrate will be very low so 51% attacks are possible. We'll be running Bitcoin ABC in beta mode and we don't guarantee neither its stability, nor that we'll run it if the chain won't be used by businesses. Once the situation becomes more stable we'll update the documentation. At the moment, other parts of the documentation don't reflect Bitcoin ABC support, so please assume that for every bitcoin-cash endpoint there's a bitcoin-abc equivalent except for https://api.blockchair.com/bitcoin-cash/nodes.

There are also following testnets supported which are technically considered as separate blockchains:

Blokchain	Group	API path prefix	Support status
Bitcoin Testnet	Bitcoin-like	`https://api.blockchair.com/bitcoin/testnet`	Full support
Ethereum Goerli Testnet	Ethereum-like	`https://api.blockchair.com/ethereum/testnet`	Development mode, no guaranteed stability

We aim to support more blockchains (and their testnets) in future to cover as many users as possible. We don't disclose which blockchains we'll add next and how we choose them, but our main markers are daily number of real transactions and market capitalization. If you're representing a coin community which would like to add its blockchain to our platform, we'd be happy to talk.

As a general rule, if we add a blockchain to our platform, it means we'll support it and related functions indefinitely. However, there are some exceptions:

Since a blockchain system can be an unstable product, we may cease support in case the blockchain itself (or the node software we're using) stops to function or starts to function improperly;
If a blockchain hard-forks and that results in a new ruleset we can't support for technical or other reasons, we may either drop support for this blockchain, or don't accept the new ruleset;
If a blockchain is community-backed, we guarantee support till some specified date (this is reflected in the tables above). If its community decides not to prolong the agreement with Blockchair after that date, we may either continue to support that blockchain for free, or drop support for it;
If we see that a particular blockchain became unpopular on our platform, we may terminate its support with a 3 month notice.

For some of the blockchains we support we don't store full historical data. These blockchains are: Ripple, Stellar, EOS. That means you won't be able to query some old blocks, and the transaction list for an address may not show some old transactions. See Available block ranges API endpoint to get data on which blocks are available in these blockchains. All other blockchains have full historical data. It's our intent to have full historical data for all blockchains.

Blockchair API also supports 2 layer 2 solutions (tokens) divided into 2 groups:

Omni-like tokens (Omni Layer on top of Bitcoin)
ERC-20-like tokens (ERC-20's on top of Ethereum)

Like with blockchains, within a group, there's no or little difference between the available endpoints.

Layer 2	Group	Parent blockchain	API path prefix	Support status
Omni Layer	Omni-like	Bitcoin	`https://api.blockchair.com/bitcoin/omni`	Alpha support
ERC-20	ERC-20-like	Ethereum	`https://api.blockchair.com/ethereum/erc-20`	Beta support

We also plan to bring ERC-721 support in the future.

Ethereum Goerli Testnet also supports ERC-20's.

Wormhole support was dropped on January 1st, 2020 with a 3-month notice as it's not used by anyone anymore.

Please note there are some endpoints which aren't listed here (most of the times they have the https://api.blockchair.com/internal prefix), but used by our web interface — these endpoints aren't meant to be used by 3rd parties.

The base request cost is used only if there are no additional parameters included in the request, and the default limits on the number of results are used. For example, if you're requesting info on ERC-20 tokens while getting data on an Ethereum address using a special parameter or increasing the number of latest transactions for this address, you may be charged additional request points. c in formulas means "number of requested entities". d means "depth" (applied to xpub lookups). Detailed cost formulas are available in the corresponding documentation sections.

Basic API request

Requests to the API should be made through the HTTPS protocol by GET requests to the domain api.blockchair.com. Here's an example request URL: https://api.blockchair.com/bitcoin/blocks?a=sum(generation)

> curl 'https://api.blockchair.com/bitcoin/blocks?a=sum(generation)'
{"data":[{"sum(generation)":1800957104497237}],"context":{"code":200,"source":"A","time":0.007825851440429688,"limit":10000,"offset":null,"rows":1,"pre_rows":1,"total_rows":1,"state":600767,"cache":{"live":true,"duration":60,"since":"2019-10-23 21:33:00","until":"2019-10-23 21:34:00","time":null},"api":{"version":"2.0.38","last_major_update":"2019-07-19 18:07:19","next_major_update":null,"documentation":"https:\/\/github.com\/Blockchair\/Blockchair.Support\/blob\/master\/API.md","notice":"Beginning July 19th, 2019 all applications using Blockchair API on a constant basis should apply for an API key (mailto:info@blockchair.com)"}}}

Here are some considerations:

If you're building a web app, your users shouldn't make direct API requests from there. While we don't have any limitations in our CORS policy (API currently responds with a Access-Control-Allow-Origin: * header), that policy may be changed in the future without any warnings
Please don't use some random keys in your requests (e.g. ?random_key=random_value) as this can result in a 400 error (though we don't force this rule at the moment for most of our endpoints)
If you're using the API with an API key, you should keep it in secret. In order to build an app for public use using our API, you should build a proxy, so the requrst flow will look like the following: user → https://your-proxy/{:request_string} → https://api.blockchair.com/{:request_string}?key={:api_key} — that way you won't disclose the key to your users
The only exception to the "requests should be made using GET" rule is the Broadcasting transactions endpoint accepting POST requests

Basic API response

API returns JSON-encoded data. Typically, the response is an array consisting of two subarrays:

data — contains the data you requested
context — contains some metadata, e.g. a status code, query execution time, used options, etc. Here are some of it (note that not all endpoints return all of the keys listed here):
- context.code — server response code (also included in HTTP headers), can return:
  - 200 if the request succeeded
  - 400 if there is a user error in the request
  - 404 for some endpoints in case there's no results (this behavior is deprecated), also if you're requesting non-existing endpoint
  - 402, 429, 435, 436, or 437 if any limit on the number or complexity of requests is exceeded (see the list of limits, and please contact us if you'd like to increase them) — your IP address will be unblocked automatically after some time
  - 430, 434, or 503 if your IP address is temporarily blocked
  - 500 or 503 in case of a server error (it makes sense to wait and repeat the same request or open a ticket at https://github.com/Blockchair/Blockchair.Support/issues/new or write to info@blockchair.com)
- context.error — error description in the case there's an error
- context.state — number of the latest known block (e.g., for all requests to endpoints connected to the Bitcoin blockchain this will yield the latest block number for Bitcoin). For example, it may be useful to calculate the number of network сonfirmations, or correctly iterate trough the results using ?offset=. Not returned if the request has failed.
- context.state_layer_2 — the latest block number for which our engine has processed second layer (e.g. ERC-20) transactions. If it's less than the block id in your current environment (e.g. block id of a transaction you requested), it makes sense to repeat the request after some time to retrieve second layer data. With our current architecture it always equals to context.state, but that may change in future.
- context.results — contains the number of found results (dashboard and raw endpoints)
- context.limit — applied limit to the number of results (the default one or user set in the ?limit= query section)
- context.offset — applied offset (the default one or user set in the ?offset= query section)
- context.rows — contains the number of shown rows returned from the database (infinitable endpoints)
- context.total_rows — total number of rows meeting the request (infinitable endpoints)
- context.api — array of data on the status of the API:
  - context.api.version — version of API
  - context.api.last_major_update — timestamp of the last update, that somehow has broken backward compatibility for "stable" endpoints
  - context.api.next_major_update — timestamp of the next scheduled update, that can break compatibility, or null, if there are no updates scheduled
  - context.api.documentation — an URL to the latest version of documentation
  - context.api.notice — just a text notice which, for example, may describe upcoming changes (this is an optional field)
- context.cache — array of info on whether the response comes from the cache or not
  - context.cache.live — false if the response comes from the cache, true otherwise
  - context.cache.until — cache expiry timestamp
- context.request_cost — API request cost (1 for ordinary queries, more than 1 for complex requests, see the next section for details)

There are also some things which are the same across all endpoints:

All timestamps are in the UTC timezone, and have the following format: YYYY-MM-DD hh:ii:ss . If you require an ISO 8601 timestamp with the timezone, just replace the space with a T, and append Z to the timestamp (e.g. 2009-01-03 18:15:05 will then become 2009-01-03T18:15:05Z)
There are some endpoints allowing you to request data in formats other than JSON (e.g. TSV or CSV). In that case, the API returns plain output data in the desired format without metadata
Most of the responses are cached for some amount of time. Bypassing cache is allowed in some of our Premium API plans (see the next documentation section)

API rate limits, API keys, and Premium API

While we do allow to perform some amount of requests free of charge, generally our API is not free to use.

Here's our policy:

If you use our API occasionally for personal use or testing up to 1440 requests a day (1 request a minute in average) — a key is not required
Non-commercial and academic projects which require up to 1440 requests a day — a key is not required
Non-commercial and academic projects requiring more than 1440 requests a day should apply for a Premium API key, and are subject to a discount up to 50%
Non-commercial and academic projects requiring more than 1440 requests a day which are also Blockchair partners are subject to a discount up to 100%
Commercial projects should apply for a key to Premium API not depending on the required number of requests
Commercial projects which are also Blockchair partners (e.g. linking to Blockchair from the app's interface) are subject to a discount up to 10%

	Up to 1440 requests a day	More than 1440 requests a day
Personal or testing	Key is not needed	Key is required
Non-commercial or academic	Key is not needed	Key is required, up to 100% discount
Commercial	Key is required	Key is required, up to 10% discount

Our Premium API plans are available here: https://blockchair.com/api/plans, please contact us if you have any questions or would like to have a custom plan.

The daily request counter is reset at 00:00 UTC every day.

There's an additional hard limit of 30 requests per minute on the free plan.

If you exceed the limit, an error 402 or 429 will be returned. On some of our Premium API plans it's possible to "borrow" requests from the next day if you hit the limit (if your daily limit is n and you hit it, n more requests will be added to the limit for 1 day, you will be notified, and your subscription period will shrink by 1 day) — this behavior is turned off by default.

There's an additional soft limit of 5 requests per second on both free and paid plans. This limit is applied only if we experience a very high load on our servers, and it's turned on and off manually by our admins. In case you hit this limit, an error 435 will be returned.

If you have exceeded the limit multiple times without using a key, an error 430, 434, or 503 may be returned meaning that you've been blocked. It's also possible to get automatically blocked without exceeding the limit in case we're seeing botnet usage in order to bypass the limit. If you've been blocked and you believe you haven't abused our API above the limit, please contact us. If you're using a valid API key it's not possible to get blocked; if you've been previously blocked and starting to use a key, you'll get automatically unblocked.

Please note that some of API requests may "cost" more than 1 request. Here's an example:

https://api.blockchair.com/bitcoin/dashboards/block/0 — requesting information about one block via one request "costs" 1 request
https://api.blockchair.com/bitcoin/dashboards/blocks/0,1,2,3,4,5,6,7,8,9 — requesting information about ten blocks via one request "costs" 1.9 requests

Every API endpoint documentation has the "Request cost formula" section describing how the "cost" is calculated. For most API requests it's always 1. It's more than 1 in cases when you're requiring additional data (e.g. when you're requesting data on an Ethereum address, and you're also requesting its ERC-20 token balances).

Every API response yields context.request_cost with the request cost number ("request points").

As a kindly reminder, there are tasks such as extracting lots of blockchain data (e.g. all transactions over a 2 month period) which require lots of requests done — it may be better to use our Database dumps feature instead of the API (see https://blockchair.com/dumps for documentation)

What are the steps to acquire an API key?

Our Premium API dashboard is available here: https://api.blockchair.com/premium

First, you need to choose a suitable plan: https://blockchair.com/api/plans

At the moment, this automated system accepts PayPal payments only (which also allows you to pay with your card). If you'd like to pay via wire transfer or crypto, please contact us at info@blockchair.com

Once you've paid, you will receive a one-time password which can be used to generate and activate your API key. Enter it on this page into the "I want to activate an API key I've just purchased..." form, then fill in a small form about yourself, and you'll get the key.

After you have received a key, you can track your stats and extend your subscription. Enter your API key on this page into the "I already have an API key and would like to see some stats or extend my subscription..." form. If you'd like to extend your subscription, you'd need to buy a one-time extension password and enter it on your key management page.

If you have any questions about how to buy and use your key, you can always contact us.

In order to use an API key, you need to append ?key={:api_key} or &key={:api_key} to the end of request URLs. You should use ? if there are no other parameters in the URL, and & otherwise. Here are three examples of correct URLs with a key:

https://api.blockchair.com/bitcoin/dashboards/block/0?key=myfirstpasswordwas4321andifeltsmartaboutit
https://api.blockchair.com/bitcoin/dashboards/block/0?limit=0&key=myfirstpasswordwas4321andifeltsmartaboutit
https://api.blockchair.com/bitcoin/dashboards/block/0?key=myfirstpasswordwas4321andifeltsmartaboutit&limit=0

There's an extra API endpoint for those who have an API key allowing to track the number of request made.

API versioning and changelog

As a reminder, there's the context.api array in every API response which contains the following data:

context.api.version — version of API
context.api.last_major_update — timestamp of the last update, that somehow has broken backward compatibility for "stable" endpoints
context.api.next_major_update — timestamp of the next scheduled update, that can break compatibility, or null, if there are no updates scheduled
context.api.documentation — an URL to the latest version of documentation
context.api.notice — just a text notice which, for example, may describe upcoming changes (this is an optional field)

When we change something, or add new functions, we bump the API version number. Generally, we try as hard as possible not to bring any compatibility-breaking changes in API updates, but sometimes this is needed as some blockchains change their features themselves, we're fixing various bugs, etc. This doesn't apply, however, to changes to endpoints which are either marked as alpha- or beta-stage functions, or unstable in nature (e.g. all raw endpoints where the API returns data directly from our nodes, and the response may change as we upgrade the nodes). These marks are reflected in the Quick endpoint reference.

The changelog is available here: https://github.com/Blockchair/Blockchair.Support/blob/master/API.md

It makes sense to check if context.api.version has increased and/or just whether context.api.next_major_update is not null or larger than the latest update date known to you. If that's the case — you can send yourself a notification and review the changelog to make your application compatible with the changes starting from context.api.next_major_update.

General stats endpoints

Omni Layer stats

Allows to retrieve the some basic stats on Omni Layer (Bitcoin). Note that this endpoint is in the Alpha stage, and Wormhole (Bitcoin Cash Omni-like token system) was phased out on January 1st, 2020.

Endpoint:

https://api.blockchair.com/bitcoin/omni/stats

Output:

data contains an array with second layer statistics:

properties — total number of created properties
properties_mainnet — total number of "mainnet" properties
properties_testnet — total number of "testnet" properties
transactions_approximate — approximate number of transactions
latest_transactions — array of 10 latest transactions

Note that the "mainnet" and "testnet" terms don't imply using Bitcoin Testnet, the idea behind that is "testnet" properties still live on the Bitcoin Mainnet, but they have should have no monetary value, and their purpose is for testing only.

There's no separate endpoint to get ERC-20 stats, use https://api.blockchair.com/ethereum/stats instead which includes ERC-20 info. Description is available here

Dashboard endpoints

Retrieve information about various entities in a neat format from our databases

The API supports a number of calls that produce some aggregated data, or data in a more convenient form for certain entities.

Dashboard endpoints for Bitcoin-like blockchains (Bitcoin, Bitcoin Cash, Litecoin, Bitcoin SV, Dogecoin, Dash, Groestlcoin, Zcash, eCash, Bitcoin Testnet)

Block info

Endpoints:

https://api.blockchair.com/{:btc_chain}/dashboards/block/{:height}₀
https://api.blockchair.com/{:btc_chain}/dashboards/block/{:hash}₀
https://api.blockchair.com/{:btc_chain}/dashboards/blocks/{:height}₀,...,{:height}ᵩ (up to 10 blocks, comma-separated)
https://api.blockchair.com/{:btc_chain}/dashboards/blocks/{:hash}₀,...,{:hash}ᵩ (up to 10 blocks, comma-separated)

Where:

{:btc_chain} can be one of these: bitcoin, bitcoin-cash, litecoin, bitcoin-sv, dogecoin, dash, groestlcoin, zcash, ecash, bitcoin/testnet
{:height}ᵢ is the block height (integer value), also known as block id
{:hash}ᵢ is the block hash (regex: /^[0-9a-f]{64}$/i)

Possible options:

?limit={:limit} limits the number of returned transaction hashes contained in the block. Default is 100. Maximum is 10000. In case of 0 returns an empty transaction hashes array
?offset={:offset} allows to paginate transaction hashes. Default is 0. Maximum is 1000000.

Output:

data contains an associative array where found block heights or block hashes used as keys:

data.{:id}ᵢ.block - information about the block (see Bitcoin-like block object for the field descriptions)
data.{:id}ᵢ.transactions - the array of transaction hashes (sorted by position in the block ascending) included in the block (respecting the set limit and offset)

Where {:id}ᵢ is either {:height}ᵢ or {:hash}ᵢ from the query string. If there's no {:id}ᵢ has been found in the database, there won't be such key.

Note that the total number of transactions in the block is contained in data.{:id}ᵢ.block.transaction_count

Context keys:

context.results — number of found blocks
context.limit — applied limit
context.offset — applied offset
context.state — best block height on the {:btc_chain} chain (tip: it's possible to calculate the number of confirmation block received using this formula: confirmations = context.state - data.{:id}ᵢ.block.id + 1)

Transaction info

Endpoints:

https://api.blockchair.com/{:chain}/dashboards/transaction/{:hash}₀
https://api.blockchair.com/{:chain}/dashboards/transactions/{:hash}₀,...,{:hash}ᵩ (up to 10 transactions, comma-separated)

Where:

{:chain} can be one of these: bitcoin, bitcoin-cash, litecoin, bitcoin-sv, dogecoin, dash, groestlcoin, zcash, ecash, bitcoin/testnet
{:hashᵢ} is the transaction hash (regex: /^[0-9a-f]{64}$/i), also known as txid

Possible options:

?omni=true (for bitcoin only; in alpha test mode) — shows information about Omni Layer token transfers in this transaction

Output:

data contains an associative array where found transaction hashes are used as keys:

data.{:hash}ᵢ.transaction — information about the transaction (see Bitcoin-like transaction object)
data.{:hash}ᵢ.inputs — the array of transaction inputs (sorted by spending_index ascending), where each element is a Bitcoin-like output object (inputs represented as spent outputs), or an empty array in case of coinbase transaction
data.{:hash}ᵢ.outputs — the array of transaction outputs (sorted by index ascending), where each element is a Bitcoin-like output object

Additional data:

data.{:hash}ᵢ.layer_2.omni (for bitcoin only; in alpha test mode) — Omni layer transaction data in case there's any
scripthash_type field for inputs and outputs (example: https://api.blockchair.com/bitcoin/dashboards/transaction/4d41241148a7cb8f4e2820d4393415ccd3d0793053a3855b44c33e5053c231ff) in the multisig_{:m}_of_{:n} format. Please note that if output is unspent, scripthash_type will always be null, even if the associated address multisig type can be derived from some other spent output.
data.{:hash}ᵢ.transaction.is_rbf (for bitcoin and bitcoin/testnet only) — yields true if the transaction can be replaced with a transaction with a higher fee (replace-by-fee), and false otherwise; for blockchain transactions it shows whether the transaction could've been replaced before it has been included into the block.

In case transaction is confirmed on the blockchain, data.{:hash}ᵢ.transaction.block_id contains the block number it's included in. If the transaction is in the mempool, data.{:hash}ᵢ.transaction.block_id yields -1. If the transaction is neither present in the blockchain, nor in the mempool, there won't be data.{:hash}ᵢ key with data.

Context keys:

context.results — number of found transactions
context.state — best block height on the {:chain} chain (tip: it's possible to calculate the number of confirmation transaction received using this formula: confirmations = data.{:id}ᵢ.transaction.block_id - context.state + 1, or if data.{:id}ᵢ.transaction.block_id is -1 it's an unconfirmed transaction)

Bonus endpoint:

https://api.blockchair.com/{:btc_chain}/dashboards/transaction/{:hash}₀/priority

For mempool transactions shows priority (position) — for chains supporting SegWit by fee_per_kwu, for others by fee_per_kb— over other transactions (out_of mempool transactions). position is null if the transaction is neither in the mempool nor in the blockchain, confirmed if it's in the blockchain. eta_seconds returns an approximate time for the transaction to confirm (in seconds, exprimental). Cost: 1.

Request cost formula:

1 for https://api.blockchair.com/{:btc_chain}/dashboards/transaction/{:hash}₀ endpoint
1 + (0.1 * (entity count - 1)) for https://api.blockchair.com/{:btc_chain}/dashboards/transactions/{:hash}₀,...,{:hash}ᵩ endpoint (e.g. it's 1 + (0.1 * (10 - 1)) = 1.9 for requesting 10 transactions)
Using ?omni=true adds 1 for each requested transaction

Address and extended public key (xpub) info

Endpoints:

https://api.blockchair.com/{:btc_chain}/dashboards/address/{:address}₀ (for a single address; further referred to as the address dashboard)
https://api.blockchair.com/{:btc_chain}/dashboards/addresses/{:address}₀,...,{:address}ᵩ (for a set of up to 100 addresses, comma-separated, further referred to as the addresses dashboard)
https://api.blockchair.com/{:btc_chain}/dashboards/xpub/{:extended_key} (info on xpub, ypub, or zpub extended key; further referred to as the xpub dashboard)

Where:

{:btc_chain} can be one of these: bitcoin, bitcoin-cash, litecoin, bitcoin-sv, dogecoin, dash, groestlcoin, zcash, ecash, bitcoin/testnet
{:address}ᵢ is the address, possible formats are:
- p2pk/p2pkh format (supported for all blockchains, example for Bitcoin: 1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa)
- p2sh format (supported for all blockchains, example for Bitcoin: 342ftSRCvFHfCeFFBuz4xwbeqnDw6BGUey)
- Only for the dashboards/address endpoint Bitcoin Cash also supports Legacy address variant, and Bitcoin SV supports CashAddr variant for p2pkh and p2sh formats. It's also possible to use bitcoincash: prefix (examples: qzyl04w3m99ddpqahzwghn3erallm3e7z5le4aqqmh or bitcoincash:qzyl04w3m99ddpqahzwghn3erallm3e7z5le4aqqmh for both Bitcoin Cash and Bitcoin SV.

- Internal Blockchair format (for multisig. nulldata, and nonstandard output types)
- For eCash the ecash: prefix and format are used
{:extended_key} is the extended public key, possible formats are:
- xpub (supported for all blockchains, example for Bitcoin: xpub6CUGRUonZSQ4TWtTMmzXdrXDtypWKiKrhko4egpiMZbpiaQL2jkwSB1icqYh2cfDfVxdx4df189oLKnC5fSwqPfgyP3hooxujYzAu3fDVmz, yields p2pkh addresses)
- ypub (supported for Bitcoin, Litecoin, Groestlcoin, and Bitcoin Testnet only, example for Bitcoin: ypub6XiW9nhToS1gjVsFKzgmtWZuqo6V1YY7xaCns37aR3oYhFyAsTehAqV1iW2UCNtgWFQFkz3aNSZZbkfe5d1tD8MzjZuFJQn2XnczsxtjoXr, yields p2sh addresses)
- zpub (supported for Bitcoin, Litecoin, Groestlcoin, and Bitcoin Testnet only, example for Bitcoin: ypub6XiW9nhToS1gjVsFKzgmtWZuqo6V1YY7xaCns37aR3oYhFyAsTehAqV1iW2UCNtgWFQFkz3aNSZZbkfe5d1tD8MzjZuFJQn2XnczsxtjoXr, yields witness_v0_keyhash addresses)
Note that custom xpub formats (e.g. ltub for Litecoin) are not supported.

Possible options:

?limit={:transaction_limit},{:utxo_limit} or a shorthand ?limit={:limit}. {:transaction_limit} limits the number of returned latest transaction hashes (in the transactions array) for an address or an address set. Default is 100. Maximum is 10000. In case of 0 returns an empty transaction hashes array. {:utxo_limit} limits the number of returned latest UTXOs (in the utxo array) for an address or an address set. Default is 100. Maximum is 10000. In case of 0 returns an empty UTXO array. If only one limit is set, it applies to both {:transaction_limit} and {:utxo_limit} (e.g. ?limit=100 is an equivalent of ?limit=100,100).
?offset={:transaction_offset},{:utxo_offest} or a shorthand ?offset={:offset} allows to paginate transaction hashes and the UTXO array. The behaviour is similar to the ?limit= section. Default for both offset is 0, and the maximum is 1000000.
?transaction_details=true — returns detailed info on transactions instead of just hashes in the transactions array. Each element contains block_id, transaction_hash, time, and balance_change (shows how the transactions affected the balance of {:address}, i.e. it can be a negative value). This option is available for all three endpoints: dashboards/address, dashboards/addresses, and dashboards/xpub.
?omni=true (for bitcoin only; in alpha test mode) — shows information about Omni Layer tokens belonging to the address. At the moment, this option is available for the address endpoint only. The data is returned in the layer_2.omni array.
?state=latest — discards unconfirmed transactions from the output — balance will show only confirmed balance, and transactions and utxo arrays won't include unconfirmed data.

Output:

Please note that while the only difference between for example transaction and transactions dashboards is the number of elements in the data array, address and addresses differ semantically. address returns info on a single address with its recent transaction hashes and its UTXO set, while addresses and xpub return info on an address set (as well as some stats on separate addresses) where transaction hashes and the UTXO set are returned for the entire set (that's more useful for wallets as in most cases the task is, for example, to retrieve latest 10 transaction hashes for a set of addresses sorted by time descending, but not 10 transactions for each address as it's not clear how to sort them).

Here's how these three dashboard calls structured (see more detailed examples below):

address endpoint (single address):

data
- {:address}₀
  - address — an associative array with address info (balance, script_hex, transaction_count, etc.)
  - transactions — an array of latest transaction hashes where the address is a participant (either sender or recipient)
  - utxo — the UTXO set for the address
context — some context info

addresses endpoint (2 addresses for example):

data
- set — an associative array with info on the address set (balance yields the total balance of 2 addresses, transaction_count is for both, etc.)
- addresses
  - {:address}₀ — an associative array with the first address info (balance, script_hex, output_count, etc.)
  - {:address}₁ — an associative array with the second address info (balance, script_hex, output_count, etc.)
- transactions — an array of latest transaction hashes for the entire set
- utxo — the UTXO set for the address set
context — some context info

xpub endpoint:

data
- {:extended_key}
  - xpub — an associative array with xpub info (balance yields the total balance of all addresses derived from the xpub, transaction_count, etc.)
- addresses
  - {:address}₀ — an associative array with the first address info (balance, script_hex, output_count, etc.)
  - {:address}₁ — an associative array with the second address info (balance, script_hex, output_count, etc.)
- transactions — an array of latest transaction hashes for the entire set
- utxo — the UTXO set for the address set
context — some context info

Note that currently the maximum depth for xpub address discovery is 250 main addresses and 250 change addresses (larger limits up to 10.000 main / 10.000 change are available on Premium plans). According to BIP 32, our engine looks for 20 addresses at once, and if there's no transactions associated with this set, it stops looking.

data.addresses for both the addresses and the xpub endpoints don't include addresses which don't participate in transactions.

Address object specification:

type — address type (the same as type here, can be one of these: pubkey (P2PK), pubkeyhash (P2PKH), scripthash (P2SH), multisig, nulldata (OP_RETURN), nonstandard, witness_v0_keyhash (P2WPKH), witness_v0_scripthash (P2WSH), witness_unknown)
script_hex — output script (in hex) corresponding to the address
balance — address balance in satoshi (hereinafter — including unconfirmed outputs unless ?state=latest option is used)
balance_usd — address balance in USD
received — total received in satoshi
received_usd — total received in USD
spent — total spent in satoshi
spent_usd — total spent in USD
output_count — the number of outputs this address received
unspent_output_count — number of unspent outputs for this address (i.e. the number of inputs for an address can be calculated as output_count-unspent_output_count)
first_seen_receiving — timestamp (UTC) when the first time this address received coins
last_seen_receiving — timestamp (UTC) when the last time this address received coins
first_seen_spending — timestamp (UTC) when the first time this address sent coins
last_seen_spending — timestamp (UTC) when the last time this address sent coins
transaction_count — number of unique transactions this address participating in (available only in the address endpoint)
path — derived address path (available only in the xpub endpoint)
scripthash_type — in case the type is either scripthash (P2SH) or witness_v0_scripthash (P2WSH) — yields multisig type in the following format: multisig_{:m}_of_{:n}. If it's not multisig, or it's not possible to derive the type because there has been no spendings from this address — yields null. Available only in the address endpoint.

Context keys:

context.results — number of found addresses
context.limit — applied limit
context.offset — applied offset
context.state — best block height on the {:btc_chain} chain (tip: it's possible to calculate the number of confirmation block received using this formula: confirmations = context.state - data.{:id}ᵢ.block.id + 1)
context.checked (for the xpub endpoint only) — lists the addresses checked by our engine with their paths

Request cost formula:

1 for the address endpoint (add 1 if ?omni=true is used)
1 + (0.1 * (entity count - 1)) for the addresses endpoint (e.g. it's 1 + (0.1 * (100 - 1)) = 10.9 for requesting 100 addresses)
1 + 2 * depth - 0.1 for the xpub endpoint, where depth is the number of 20-addresses iterations (BIP 32 standard). The minimum number of iterations is 1 (the cost would be 2.9 in that case), if there are 5 iterations required, 100 addresses will be checked in total (the cost would be 10.9)
Additional 1 point if ?transaction_details=true is used

Address balance mass check

This endpoint returns confirmed balances only. If address hasn't been seen on the blockchain or has a zero balance, it's not shown among the results. It's extremely fast (under 1 second for 25.000 addresses) and cheap (it costs only 26 request points to fetch 25.000 addresses).

Endpoints:

https://api.blockchair.com/{:btc_chain}/addresses/balances (POST)
https://api.blockchair.com/{:btc_chain}/addresses/balances?addresses={:comma_separated_list} (GET)

Where:

{:btc_chain} can be one of these: bitcoin, bitcoin-cash, litecoin, bitcoin-sv, dogecoin, dash, groestlcoin, zcash, ecash, bitcoin/testnet
{:comma_separated_list} is the comma-separated list of addresses (up to 25.000)

Example output:

https://api.blockchair.com/bitcoin/addresses/balances?addresses=34xp4vRoCGJym3xR7yCVPFHoCNxv4Twseo,35hK24tcLEWcgNA4JxpvbkNkoAcDGqQPsP,1DoesntExist:

    "results": 2,
    "state": 635329,
    "request_cost": 1.003,
    ...
  }
}

Example POST request:

> curl -v --data "addresses=34xp4vRoCGJym3xR7yCVPFHoCNxv4Twseo,35hK24tcLEWcgNA4JxpvbkNkoAcDGqQPsP,1DoesntExist" https://api.blockchair.com/bitcoin/addresses/balances

(it's better to use POST for long requests)

Request cost formula:

1 + 0.001 per each requested address (i.e. for 25.000 addresses it's just 25, so it's the best and the fastest way to fetch balances)

Dashboard endpoints for Ethereum

Block info

Endpoints:

https://api.blockchair.com/{:eth_chain}/dashboards/block/{:height}₀
https://api.blockchair.com/{:eth_chain}/dashboards/block/{:hash}₀
https://api.blockchair.com/{:eth_chain}/dashboards/blocks/{:height}₀,...,{:height}ᵩ (up to 10 blocks, comma-separated)
https://api.blockchair.com/{:eth_chain}/dashboards/blocks/{:hash}₀,...,{:hash}ᵩ (up to 10 blocks, comma-separated)

Where:

{:eth_chain} can only be: ethereum or ethereum/testnet
{:height}ᵢ is the block height (integer value), also known as block id
{:hash}ᵢ is the block hash (regex: /^0x[0-9a-f]{64}$/i)

Possible options:

?limit={:limit} limits the number of returned transaction hashes contained in the block. Default is 100. Maximum is 10000. In case of 0 returns an empty transaction hashes array
?offset={:offset} allows to paginate transaction hashes. Default is 0. Maximum is 1000000.

Output:

data contains an associative array where found block heights or block hashes used as keys:

data.{:id}ᵢ.block — information about the block (see Ethereum-like block object for the field descriptions)
data.{:id}ᵢ.transactions — the array of transaction hashes (sorted by position in the block ascending) included in the block (respecting the set limit and offset)
data.{:id}ᵢ.synthetic_transactions — array of internal Blockchair ids of synthetic transactions. By synthetic transactions we understand state changes in the blockchain which don't have parental transaction entities, i.e. transferring miner reward (for blocks and uncles), coin generation in the genesis block, etc. This array is not iterable, and always yields the entire result set.
data.{:id}ᵢ.uncles — the array of hashes of the block's uncles (in case there are no uncles — an empty array). This array is not iterable as well, and always yields the entire result set.

Where {:id}ᵢ is either {:height}ᵢ or {:hash}ᵢ from the query string.

If there's no {:id}ᵢ has been found in the database, there won't be such key.

Note that the total number of transactions in the block is contained in data.{:id}ᵢ.block.transaction_count, but that doesn't take synthetic transactions into account (use data.{:id}ᵢ.block.synthetic_transaction_count instead)

Context keys:

context.results — number of found blocks
context.limit — applied limit
context.offset — applied offset
context.state — best block height on the {:eth_chain} chain (tip: it's possible to calculate the number of confirmation block received using this formula: confirmations = context.state - data.{:id}ᵢ.block.id + 1)

context.state: best block height on the {:eth_chain} chain (tip: it's possible to calculate the number of confirmation transaction received using this formula: confirmations = data.{:id}ᵢ.transaction.block_id - context.state + 1, or if data.{:id}ᵢ.transaction.block_id is -1 it's an unconfirmed transaction)

Transaction info

Endpoints:

https://api.blockchair.com/{:eth_chain}/dashboards/transactions/{:hash}₀,...,{:hash}ᵩ (up to 10 transactions, comma-separated)

Where:

{:eth_chain} can only be: ethereum or ethereum/testnet
{:hashᵢ} is the transaction hash (regex: /^0x[0-9a-f]{64}$/i), also known as txid

Possible options:

?erc_20=true shows information about ERC-20 token transfers in this transaction
?effects=true shows state changes for the transaction
?trace_mempool=true — this option tries to retrieve a list of internall calls for mempool transactions. In conjunction with &erc_20=true it also shows the list of ERC-20 transfers. This is an experimental feature. Please note that internal transfers may get invalidated when transaction gets confirmed.
?assets_in_usd=true — adds value_usd_now to all layer_2.erc_20 items yielding the current (not at the moment of the transaction!) USD value of tokens (null if the price is unknown)
?events=true — this option costs 1 additional request point to use. When enabled, it adds an array of event logs to the output. Every log contains topics, data, contract, log_index, and decoded_event. Depending on how much our API knows about the event signature, there are 3 detalization levels for decoded_event (example transaction with all 3: https://api.blockchair.com/ethereum/dashboards/transaction/0x7d52cf58fe78403e8816dae6e900baff92b35760b4ed81cecd2590eafcde3dad?events=true):
- Full data: decoded_event contains both the full event name with its argument names (name_full, example: Approval(address owner, address spender, uint256 value)), and the argument values in the arguments array;
- Partial data: only name_with_types is known (example: Withdrawal(address, uint256)), arguments yields null;
- No data: decoded_event yields null.

Output:

data contains an associative array where found transaction hashes are used as keys:

data.{:hash}ᵢ.transaction — information about the transaction (see Ethereum-like transaction object)
data.{:hash}ᵢ.calls — the array of all calls made during the execution of the transaction (always null for mempool transactions and the last 6 blocks)

Additional data:

data.{:hash}ᵢ.layer_2.erc_20 (only if ?erc_20=true is set) — an array of ERC-20 transfers (or an empty array if there are none), Each array element contains the following keys: token_address, token_name, token_symbol, token_decimals, sender, recipient, value — field descriptions are available here.
data.{:hash}ᵢ.effects (only if ?effects=true is set) — yields all ETH ad ERC-20 balance changes for the transaction in a neat format. Keys are 0x0000000000000000000000000000000000000000 for ETH or token address for ERC-20's. Each array element contains the following keys: asset_type, asset_name, asset_symbol, asset_decimals, changes. changes is an array containing all the changes for the asset (keys are Ethereum addresses, and values are balance changes). Please note this option is experimental. Example request: https://api.blockchair.com/ethereum/dashboards/transaction/0xd9a24f57c713207c39c58e8ef3cb44e115fcc8bd0f85eb4ea82c78bc065a723f?effects=true&erc_20=true. If ?erc_20=true option is not used, ?effects=true won't yield ERC-20 data.

Context keys:

context.results — number of found transactions
context.state — best block height on the {:eth_chain} chain (tip: it's possible to calculate the number of confirmation transaction received using this formula: confirmations = data.{:id}ᵢ.transaction.block_id - context.state + 1, or if data.{:id}ᵢ.transaction.block_id is -1 it's an unconfirmed transaction)
context.state_layer_2 — the latest block number for which our engine has processed second layer (e.g. ERC-20) transactions. If it's less than the block id in your current environment (e.g. block id of a transaction you requested), it makes sense to repeat the request after some time to retrieve second layer data

Bonus endpoint:

https://api.blockchair.com/{:eth_chain}/dashboards/transaction/{:hash}₀/priority

For mempool transactions shows priority (position) by gas_price over other transactions (out_of mempool transactions). position is null if the transaction is not in the mempool. eta_seconds returns an approximate time for the transaction to confirm (in seconds, exprimental). Cost: 1.

Request cost formula:

1 for https://api.blockchair.com/{:eth_chain}/dashboards/transaction/{:hash}₀ endpoint
1 + (0.1 * (entity count - 1)) for https://api.blockchair.com/{:eth_chain}/dashboards/transactions/{:hash}₀,...,{:hash}ᵩ endpoint (e.g. it's 1 + (0.1 * (10 - 1)) = 1.9 for requesting 10 transactions)
Using ?erc_20=true adds 1 for each requested transaction
Using ?effects=true adds 1 for each requested transaction
Using ?events=true adds 1 for each requested transaction

Address info

Endpoint:

https://api.blockchair.com/{:eth_chain}/dashboards/address/{:address}₀

Where:

{:eth_chain} can only be: ethereum or ethereum/testnet
{:address}ᵢ is an Ethereum address (either an account or a contract, the address should start with 0x)

Possible options:

?limit={:call_limit} — limits the number of returned latest calls associated with the address. Default is 100. Maximum is 10000.
?offset={:call_offset} — allows to paginate calls. Default is 0, and the maximum is 1000000.
?erc_20={...} — returns information about ERC-20 token balances of the address (tokens are sorted by market capitalization descending):
- ?erc_20=approximate (or ?erc_20=true, default) — yields all token balances from our database. These values may miss some non-standard transfers in tokens that don't follow the ERC-20 standard in full. Please double-check if this option returns correct values for the tokens you'd want to get information about. Using this option costs 1.
- ?erc_20=precise — yields all token balances from our node. The process is the following: we gather information from our database about potential ERC-20 tokens the address may hold, and then for each token we call getBalance function using our node to get precise balances. Please note that if for some reason some contract doesn't follow the ERC-20 standard, our database may still miss records about the address holding this token, and there will be no request to the node about this token. So while balances yielded with this option are precise, some non-standard tokens may still be missed. Using this option costs 2.
- ?erc_20={:token_address}₀,...,{:token_address}ᵩ (recommended) — yields balances for the enlisted ERC-20 tokens from our node. That's the recommended way if you have an exact list of tokens you'd like to check. Even if some token doesn't follow the ERC-20 standard, but still has getBalance function implemented, the correct balance will be returned. Using this option costs 0.75 + 0.01 for each contract checked (the cheapest option!)
?nonce=true — returns current account nonce (mempool transactions are taken in account)
?output=type — this option scrubs all the output data except for the address type (account or contract). This may be a very fast handy way to retrieve address type instead of requesting full address data
?assets_in_usd=true — adds asset_balance_usd to the output yielding the total USD value of all (excluding ETH) account assets (currently it's most popular ERC-20 tokens only), as well as balance_usd to all layer_2.erc_20 items. If the exchange rate for a particular token is unknown, returns null for this token.
?state=latest — if this option is enabled, balance will yield the confirmed balance, and the calls array won't include unconfirmed data
?contract_details=true — if applied, it adds additional data on the address if it's a contract. At the moment, it works with ERC-20 contracts only yielding token_name, token_symbol, and token_decimals. It also yields some additional fields for all contracts: creating_transaction_hash, creating_address, and creating_transaction_time. The additional cost of using this option is 0.5

Output:

In case the address has been found, data.{:address}₀ returns an array consisting of the following elements:

address
- address.type — address type (account — for a simple address, contract — for a contract)
- address.contract_code_hex — hex code of the contract at the moment of creation (for a contract), or null for an address
- address.contract_created — for contracts only — if the contact was indeed created then true, if not (i.e. with a failed create call) — false, for a simple address yields null
- address.contract_destroyed — for contracts only — if the contact was successfully destroyed (SELFDESCTRUCT) then true, if not — false; for a simple address yields null
- address.balance — exact address balance in wei (here and below values in wei returned as strings as they don't fit into integers)
- address.balance_usd — address balance in USD (float)
- address.received_approximate — total received in wei (approximately) †
- address.received_usd — total received in USD (approximately) †
- address.spent_approximate — total spent in wei (approximately) †
- address.spent_usd — total spent in USD (approximately) †
- address.fees_approximate — total spent in transaction fees in wei (approximately) †
- address.fees_usd — total spent in transaction fees in USD (approximately) †
- address.receiving_call_count — number of calls the address has received, where value transfer occured ‡
- address.spending_call_count — number of calls that has been made by this address where value transfer occured ‡
- address.call_count — total number of calls the address participated in (may be greater than receiving_call_count + spending_call_count, because it also takes failed calls into account)
- address.transaction_count — number of transactions the address participated in
- address.first_seen_receiving — timestamp (UTC) when the address received a successful incoming call for the first time
- address.last_seen_receiving — timestamp (UTC) when the address received a successful incoming call for the last time
- address.first_seen_spending — timestamp (UTC) when the address sent a successful call for the first time
- address.last_seen_spending — timestamp (UTC) when the address sent a successful call for the last time
- address.nonce — current account nonce (only if ?nonce=true is set, null otherwise)
calls — an array of the latest address call, each element of an array containing the following elements: block_id, transaction_hash, index, time, sender, recipient, value, value_usd, transferred (see the description here)
layer_2.erc_20 (only if ?erc_20=true is set) — the array of ERC-20 token balances of the address, each element contains the following fields: token_address, token_name, token_symbol, token_decimals, balance_approximate (number of tokens), balance (exact number of tokens in the smallest denomination). Note that balance ≈ balance_approximate * 10 ^ token_decimals.

Additional data:

data.{:hash}ᵢ.layer_2.erc_20 (or an empty array if there are none), Each array element contains the following keys: token_address, token_name, token_symbol, token_decimals, sender, recipient, value — field descriptions are available here.

context.results contains the number of found addresses (0 or 1).

Notes:

† — for these fields the wei value can be rounded. For a million of calls, the rounding error can be more than 1 ether.
‡ — only those calls are counted that fit the following condition: transferred = true, i.e. calls that do not change state (including staticcall, failed calls, etc.) are not taken into account

Context keys:

context.results — number of found addresses
context.limit — applied limit
context.offset — applied offset
context.state — best block height on the {:eth_chain} chain (tip: it's possible to calculate the number of confirmation block received using this formula: confirmations = block_id - context.state + 1)
context.state_layer_2 — the latest block number for which our engine has processed second layer (e.g. ERC-20) transactions. If it's less than the block id in your current environment (e.g. block id of a transaction you requested), it makes sense to repeat the request after some time to retrieve second layer data

ERC-20 token holder info

Endpoints:

https://api.blockchair.com/ethereum/erc-20/{:token_address}/dashboards/address/{:address}
https://api.blockchair.com/ethereum/testnet/erc-20/{:token_address}/dashboards/address/{:address} (Goerli Testnet)

Where:

{:token_address} is the token contract address (should start with 0x)
{:address} is an Ethereum address (either an account or a contract, the address should start with 0x)

Possible options:

?limit={:transaction_limit} — limits the number of returned latest transactions associated with the address. Default is 100. Maximum is 10000.
?offset={:transaction_offset} — allows to paginate transactions. Default is 0, and the maximum is 1000000.

Output:

The structure is similar to the Ethereum address endpoint with the following differences:

It shows balances in tokens instead of ethers
Fields like first_seen_receiving mean "first seen receiving tokens" instead of "ethers"
Instead of the calls array, there's the transactions array with the latest token transactions (see this for field descriptions). It's iterable using the ?offset= section.

Context keys:

context.results — number of found addresses
context.limit — applied limit
context.offset — applied offset
context.state — best block height on the {:eth_chain} chain (tip: it's possible to calculate the number of confirmation block received using this formula: confirmations = block_id - context.state + 1)
context.state_layer_2 — the latest block number for which our engine has processed second layer (e.g. ERC-20) transactions. If it's less than the block id in your current environment (e.g. block id of a transaction you requested), it makes sense to repeat the request after some time to retrieve second layer data

Cross-chain checks

Multichain address check

This endpoint allows to check multiple addresses from diffrerent blockchain via just one request. This can be useful if you're monitoring your own wallet or portfolio.

Endpoint:

``https://api.blockchair.com/multi/dashboards/addresses/{:address}₀,...,{:address}ᵩ`

Where:

{:address}₀,...,{:address}ᵩ is a comma separated list of addresses in the blockchain:address format. Supported blockchains: bitcoin, bitcoin-cash, ethereum, litecoin, bitcoin-sv, dash, groestlcoin, zcash. More blockchains are coming in the future. bitcoin-cash and bitcoin-sv may be used as bitcoincash and bitcoinsv respectively. Only CashAddr format is supported for Bictoin Cash. The maximum number of addresses is 100. There can only be one Ethereum address in the list.

Output:

data.set — information on the entire set (total USD balance, etc.)
data.addresses — an array of info on addresses found
data.transactions — list of the latest transactions for this set (similar to ?transaction_details=true option for {:btc_chain}/dashboards/address endpoint)

Example output:

Request cost formula:

The total cost is the same as if you'd use dashboards/addresses endpoints for the requested blockchains separately with the ?transaction_details=true option enabled. In the example, the cost is 5.1, and it's calculated as the sum of using the following endpoints:

https://api.blockchair.com/bitcoin/dashboards/addresses/1JADsmDFX9d2TXis63S9F9L8eDAXwJmnWE,1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa?transaction_details=true (cost: 2.1)
https://api.blockchair.com/ethereum/dashboards/address/0x19DdD94B94D3c68385c897846AB44Ac99DBFAe0f (cost: 1)

Raw data endpoints

Retrieve raw information about various entities directly from our full nodes

Raw data endpoints for Bitcoin-like blockchains (Bitcoin, Bitcoin Cash, Litecoin, Bitcoin SV, Dogecoin, Dash, Groestlcoin, Zcash, eCash, Bitcoin Testnet)

Raw block data

Returns raw block data directly from our full node. If the block is larger than 10 megabytes in size, returns a 402 error.

Endpoints:

https://api.blockchair.com/{:btc_chain}/raw/block/{:height}₀
https://api.blockchair.com/{:btc_chain}/raw/block/{:hash}₀

Where:

{:btc_chain} can be one of these: bitcoin, bitcoin-cash, litecoin, bitcoin-sv, dogecoin, dash, groestlcoin, zcash, ecash, bitcoin/testnet
{:height}ᵢ is the block height (integer value), also known as block id
{:hash}ᵢ is the block hash (regex: /^[0-9a-f]{64}$/i)

Output:

data contains an associative array:

data.{:id}ᵢ.raw_block — raw block represented as a hex string
data.{:id}ᵢ.decoded_raw_block — raw block encoded in JSON by our node. Please note that the structure of this JSON array may change as we upgrade our nodes, and this won't be reflected in our change logs. We don't provide field descriptions for raw endpoints, that information can be found on the Bitcoin Core website (all Bitcoin-like blockchains the same output structure).

Where {:id}ᵢ is either {:height}ᵢ or {:hash}ᵢ from the query string. If there's no {:id}ᵢ has been found on the blockchain, returns an empty array.

Context keys:

context.state: best block height on the {:btc_chain} chain (tip: it's possible to calculate the number of confirmation block received using this formula: confirmations = context.state - data.{:id}ᵢ.block.id + 1)

Raw data endpoints for Ethereum and Ethereum Goerli Testnet

Raw block data

Returns raw block data directly from our full node.

Endpoints:

https://api.blockchair.com/{:eth_chain}/raw/block/{:height}₀
https://api.blockchair.com/{:eth_chain}/raw/block/{:hash}₀

Where:

{:eth_chain} can only be ethereum or ethereum/testnet
{:height}ᵢ is the block height (integer value), also known as block id
{:hash}ᵢ is the block hash (regex: /^0x[0-9a-f]{64}$/i)

Output:

data contains an associative array:

data.{:id}ᵢ.decoded_raw_block — raw block encoded in JSON by our node. Please note that the structure of this JSON array may change as we upgrade our nodes, and this won't be reflected in our change logs. We don't provide field descriptions for raw endpoints, that information can be found on the geth implementation website.

Where {:id}ᵢ is either {:height}ᵢ or {:hash}ᵢ from the query string. If there's no {:id}ᵢ has been found on the blockchain, returns an empty array.

Context keys:

context.state: best block height on the {:eth_chain} chain (tip: it's possible to calculate the number of confirmation block received using this formula: confirmations = context.state - data.{:id}ᵢ.block.id + 1)

Raw data endpoints for Stellar

Raw ledger data

Returns raw ledger data directly from our full node.

Endpoint:

https://api.blockchair.com/{:xlm_chain}/raw/ledger/{:height}₀

Where:

{:xlm_chain} can only be stellar
{:height}ᵢ is the ledger number (integer value)

Possible options:

?transactions=true displays transaction data

Output:

data contains an associative array:

data.{:height}ᵢ.ledger — raw ledger encoded in JSON by our node. Please note that the structure of this JSON array may change as we upgrade our nodes, and this won't be reflected in our change logs. We don't provide field descriptions for raw endpoints, that information can be found on the Stellar website.

Context keys:

context.state: best ledger height on the {:btc_chain} chain (tip: it's possible to calculate the number of confirmation block received using this formula: confirmations = context.state - data.{:id}ᵢ.block.id + 1)

Example requests:

Where:

{:xlm_chain} can only be stellar
{:hash}ᵢ is the transaction hash (regex: /^[0-9a-f]{64}$/i)

Possible options:

?operations=true displays operations data
?effects=true displays effects data

Output:

data contains an associative array:

data.{:hash}ᵢ.transaction — raw transaction encoded in JSON by our node. Please note that the structure of this JSON array may change as we upgrade our nodes, and this won't be reflected in our change logs. We don't provide field descriptions for raw endpoints, that information can be found on the Stellar website`
data.{:hash}ᵢ.operations (optional: if the parameter is not set yields null)
data.{:hash}ᵢ.effects (optional: if the parameter is not set yields null)

If there's no {:hash}ᵢ has been found on the blockchain, returns an empty array.

Raw outputs

Returns raw block data from our onion-monero-blockchain-explorer instance. See https://github.com/moneroexamples/onion-monero-blockchain-explorer/blob/master/README.md for field descriptions (api/outputs?txhash=<tx_hash>&address=&viewkey=&txprove=<0|1> section), but mostly they are self-describing.

Endpoint:

https://api.blockchair.com/{:xmr_chain}/raw/outputs?{:query}

Where:

{:xmr_chain} can only be monero
{:query} is the query string:
- txprove=0 checks which outputs belong to given address and corresponding viewkey
- txprove=1 proves the sender sent funds
- txhash is the transaction hash
- address is the address
- viewkey is the viewkey

Output:

data contains an associative array:

data.outputs — the list of outputs

Raw data endpoints for Cardano

Raw block data

Returns raw block data from our cardano-explorer-webapi instance. See https://cardanodocs.com/technical/explorer/api for field descriptions (/api/blocks/summary/{hash} section), but mostly they are self-describing. Our API also allows to query by block id.

Endpoints:

https://api.blockchair.com/{:ada_chain}/raw/block/{:height}₀
https://api.blockchair.com/{:ada_chain}/raw/block/{:hash}₀

Where:

{:ada_chain} can be only cardano
{:height}ᵢ is the block height (integer value), also known as block id
{:hash}ᵢ is the block hash (regex: /^[0-9a-f]{64}$/i)

Possible options:

?transactions=true displays transaction data

Output:

data contains an associative array:

data.{:id}ᵢ.block — block data
data.{:id}ᵢ.block — block transactions (null if ?transactions=true isn't set, an empty array [] if there are no transactions in the block )

Raw data endpoints for EOS

Raw block data

Returns raw block data directly from our node. Please note that we're not running a full history node for EOS, thus we store only the most recent blocks.

Endpoint:

https://api.blockchair.com/{:eos_chain}/raw/block/{:height}₀

Where:

{:eos_chain} can only be eos
{:height}ᵢ is the block height (integer value), also known as block id

Output:

data contains an associative array:

data.{:id}ᵢ.block — raw block data with its transactions.

Example output:

Raw transaction data

Returns raw transaction data directly from our node. Please note that we're not running a full history node for EOS, thus we store only the most recent transactions.

Endpoints:

https://api.blockchair.com/{:eos_chain}/raw/transaction/{:hash}
https://api.blockchair.com/{:eos_chain}/raw/transaction/({:block_height},{:hash})

Where:

{:eos_chain} can only be eos
{:hash} is the transaction hash
{:block_height} is the block height (specifying it returns transaction faster)

Output:

Infinitable endpoints (SQL-like queries)

These endpoints allow you to filter, sort, and aggregate blockchain data. The output is database rows. Unlike dashboard and raw endpoints, all infinitable endpoints listed in this section can be considered as just one endpoint as it has the same options and the same output structure across different blockchains and entities. Here it is: https://api.blockchair.com/{:table}{:query}.

Just don't ask why do we call that infinitables… Infinite tables? Maybe.

List of tables ({:table}) our engine supports:

{:btc_chain}/blocks
{:btc_chain}/transactions
{:btc_chain}/mempool/transactions
{:btc_chain}/outputs
{:btc_chain}/mempool/outputs
{:btc_chain}/addresses
{:eth_chain}/blocks
{:eth_chain}/uncles
{:eth_chain}/transactions
{:eth_chain}/mempool/transactions
{:eth_chain}/calls
{:xin_chain}/raw/snapshots
{:xin_chain}/raw/mintings
{:xin_chain}/raw/nodes
{:xtz_chain}/raw/blocks
bitcoin/omni/properties
ethereum/erc-20/tokens
ethereum/erc-20/transactions

Where:

{:btc_chain} can be one of these: bitcoin, bitcoin-cash, litecoin, bitcoin-sv, dogecoin, dash, groestlcoin, zcash, ecash, or bitcoin/testnet
{:eth_chain} can be only ethereum
{:xin_chain} can be only mixin
{:xtz_chain} can be only tezos

Note on mempool tables: to speed up some requests, our architecture have separate tables ({:chain}/mempool/{:entity}) for unconfirmed transactions. Unlike with dashboard endpoints which search entities like transactions in both the blockchain and the mempool, infinitable endpoints don't do that.

The {:query} is optional; in case it's not included in the request, the default sorting applied to the table (for most of the tables it's descending by some id) and the 10 top results are returned.

Here are some example queries without using {:query}:

https://api.blockchair.com/bitcoin/blocks
https://api.blockchair.com/bitcoin-cash/mempool/transactions

The output skeleton is the following:

{
  "data": [
    {
      ... // row 1 data
    },
    ...
    {
      ... // row 10 data
    },    
  ],
  "context": {
    "limit": 10, // the default limit of 10 is applied
    "offset": 0, // no offset has been set
    "rows": 10, // the response contains 10 rows
    "total_rows": N, // but there are N rows in the table matching {:query} (total number of rows if it's not set)
    "state": S, // the latest block number on the blockchain
    ...
  }
}

Further documentation sections describe fields returned for different tables. Some of the dashboard endpoints are using the same fields as well.

How to build a query

The process is somewhat similar to constructing an SQL query, but there are less possibilities of course.

Here are the possible options:

Setting filters — the ?q= section — allows you to set a number of filters (SQL "WHERE")
Setting sortings — the ?s= section — allows you to sort the table (SQL "ORDER BY ")
Setting the limit — the ?limit= section — limits the number of output results (SQL "LIMIT")
Setting the offset — the ?offset= section — offsets the result set (SQL "OFFSET")
Aggregating data — the ?a= sections — allows to group by some columns and calculate using function (SQL "GROUP BY" and functions such as count, max, etc.)
The table (SQL "FROM") is set in the {:table} section of the API request

The order of applying various sections is irrelevant.

A quick example: https://api.blockchair.com/bitcoin/blocks?q=time(2019-01),guessed_miner(AntPool)&s=size(desc)&limit=1. This request:

Makes a query to the bitcoin/blocks table
Filters the table by time (finds all blocks mined in January 2019) and miner (AntPool)
Sorts the table by block size descending
Limits the number of results to 1

What this example does is finding the largest block mined by AntPool in January 2019.

Another example using aggregation: https://api.blockchair.com/bitcoin/blocks?q=time(2019-01-01..2019-01-31)&a=guessed_miner,count()&s=count()(desc). This request:

As the previous one, makes a query to the bitcoin/blocks table
Filters the table by time (in a bit different way, but it's an invariant of time(2019-01))
Groups the table by miner, and calculating the number of rows for each miner using the count() function
Sorts the result set by the number of blocks each miner has found

The ?q= section (filters)

You can use filters as follows: ?q=field(expression)[,field(expression)]..., where field is the column which is going to be filtered, and expression is a filtering expression. These are possilble filtering expressions:

equals — equality — example: https://api.blockchair.com/bitcoin/blocks?q=id(0) finds information about block 0
left.. — non-strict inequality — example: https://api.blockchair.com/bitcoin/blocks?q=id(1..) finds information about block 1 and above
left... — strict inequality — example: https://api.blockchair.com/bitcoin/blocks?q=id(1...) finds information about block 2 and above
..right — non-strict inequality — example: https://api.blockchair.com/bitcoin/blocks?q=id(..1) finds information about blocks 0 and 1
...right — strict inequality — example: https://api.blockchair.com/ bitcoin/blocks?q=id(...1) finds information only about block 0
left..right — non-strict inequality — example: https://api.blockchair.com/bitcoin/blocks?q=id(1..3) finds information about blocks 1, 2 and 3
left...right — strict inequality — example: https://api.blockchair.com/bitcoin/blocks?q=id(1...3) finds information about block 2 only
~like — occurrence in a string (SQL LIKE '%str%' operator) — example: https://api.blockchair.com/bitcoin/blocks?q=coinbase_data_bin(~hello) finds all blocks which contain hello in coinbase_data_bin
^like — occurrence at the beginning of a string (SQL LIKE 'str%' operator, also further mentioned as the STARTS WITH operator) — example: https://api.blockchair.com/bitcoin/blocks?q=coinbase_data_hex(^00) finds all blocks for which coinbase_data_hex begins with 00

For timestamp type fields, values can be specified in the following formats:

YYYY-MM-DD HH:ii:ss
YYYY-MM-DD (converted to the YYYY-MM-DD 00:00:00..YYYY-MM-DD 23:59:59 range)
YYYY-MM (converted to the YYYY-MM-01 00:00:00..YYYY-MM-31 23:59:59 range)

Inequalities are also supported for timestamps, the left and right values must be in the same format, e.g.: https://api.blockchair.com/bitcoin/blocks?q=time(2009-01-03..2009-01-31).

Ordinarilly if there's time column in the table, there should also be date, but there won't be possible to search over the date column directly, but you can search by date using the time column as follows: ?q=time(YYYY-MM-DD)

If the left value in an inequality is larger than the right, they switch places.

If you want to list several filters, you need to separate them using commas like this: https://api.blockchair.com/bitcoin/blocks?q=id(500000..),coinbase_data_bin(~hello)

We're currently testing support for NOT and OR operators (this is an alpha test feature, so we don't guarantee there won't be sudden changes):

The NOT operator is added before the expression for it to be inverted, e.g., https://api.blockchair.com/bitcoin/blocks?q=not,id(1..) returns the block 0
The OR operator can be put between two expressions and takes precedence (like it's when two expressions around OR are wrapped in parentheses), e.g., https://api.blockchair.com/bitcoin/blocks?q=id(1),or,id(2) returns information about blocks 1 and 2.

Maximum guaranteed supported number of filters in one query: 5.

The ?s= section (sortings)

Sorting can be used as follows: ?s=field(direction)[,field(direction)]..., where direction can be either asc for sorting in ascending order, or desc for sorting in descending order.

Here's a basic example: https://api.blockchair.com/bitcoin/blocks?s=id(asc) — sorts blocks by id ascending

If you need to apply several sortings, you can list them separating with commas. The maximum guaranteed number of sortings is 2.

The ?limit= section (limit)

Limit is used like this: ?limit=N, where N is a natural number from 1 to 100. The default is 10. context.limit takes the value of the set limit. In some cases (when using some specific "increased efficiency" filters described below) LIMIT may be ignored, and in such cases the API returns the entire result set, and context.limit will be set to NULL.

A basic example: https://api.blockchair.com/bitcoin/blocks?limit=1 — returns the latest block data (as the default sorting for this table is by block height descending)

Note that increasing the limit leads to an increase in the request cost (see the formula below).

The ?offset= section (offset)

Offset can be used as a paginator, e.g., ?offset=10 returns the next 10 rows. context.offset takes the value of the set offset. The maximum value is 10000. If you need just the last page, it's easier and quicker to change the direction of the sorting to the opposite.

Important: while iterating through the results, it is quite likely that the number of rows in the database will increase because new blocks had found while you were paginating. To avoid that, you may, for example, add an additional condition that limits the block id to the value obtained in context.state in the first query.

Here's an example. Suppose we would like to receive all the latest transactions from the Bitcoin blockchain with amount more than $1M USD. The following request should be perfomed for this:

https://api.blockchair.com/bitcoin/transactions?q=output_total_usd(10000000..)&s=id(desc)

Now, the script with this request to the API for some reason did not work for a while, or a huge amount of transactions worth more than $1 million appeared. With the standard limit of 10 results, the script skipped some transactions. Then firstly we should make the same request once again:

https://api.blockchair.com/bitcoin/transactions?q=output_total_usd(10000000..)&s=id(desc)

From the response we put context.state in a variable {:state}, and further to obtain next results we apply offset and set a filter to "fix" the blockchain state:

https://api.blockchair.com/bitcoin/transactions?q=output_total_usd(10000000..),block_id(..{:state})&s=id(desc)&offset=10

Next we increase the offset value until getting a data set with the transaction that we already knew about.

The ?a= section (data aggregation)

Warning: data aggregation is currently in beta stage on our platform.

To use aggregation, put the fields by which you'd like to group by (zero, one, or several), and fields (at least one) which you'd like to calculate using some aggregate function under the ?a= section. You can also sort the results by one of the fields included in the ?a= section (asc or desc) using the ?s= section, and apply additional filters using the ?q= section.

Let's start with some examples:

https://api.blockchair.com/bitcoin/blocks?a=year,count() — get the total number of Bitcoin blocks by year
https://api.blockchair.com/bitcoin/transactions?a=month,median(fee_usd) — get the median Bitcoin transaction fees by month
https://api.blockchair.com/ethereum/blocks?a=miner,sum(generation)&s=sum(generation)(desc) — get the list of Ethereum miners (except uncle miners) and sort it by the total amount of coins minted
https://api.blockchair.com/bitcoin-cash/blocks?a=sum(fee_total_usd)&q=id(478559..) — calculate how much miners have collected in fees since the fork

In case the table you're aggregating over has a time column, it's always possible to group by the following virtual columns:

date
week (yields YYYY-MM-DD corresponding to Mondays)
month (yields YYYY-MM )
year (yields YYYY )

Supported functions:

avg({:field})
median({:field})
min({:field})
max({:field})
sum({:field})
count()

There are also two special functions:

price({:ticker1}_{:ticker2})— yields the price; works only if you group by date (or one of: week, month, year). For example, it makes it possible to build a chart showing correlation between price and transaction count: https://api.blockchair.com/bitcoin/blocks?a=month,sum(transaction_count),price(btc_usd). Supported tickers: usd, btc, bch, eth, ltc, bsv, doge, dash, grs
f({:expression}) where {:expression} is {:function_1}{:operator}{:function_2}, where {:function_1} and {:function_2} are the supported functions from the above list, and {:operator} is one of the following: +, -, /, * (basic math operators). It's useful to calculate percentages. Example: https://api.blockchair.com/bitcoin/blocks?a=date,f(sum(witness_count)/sum(transaction_count))&q=time(2017-08-24..) — calculates SegWit adoption (by dividing the SegWit transaction count by the total transaction count)

There's also a special ?aq= section which have the following format: ?aq={:i}:{:j} — it applies ith filter to jth function (special functions don't count); after that ith filter has no effect on filtering the table. It's possible to have multiple conditions by separating them with a ;. Here's an example: https://api.blockchair.com/bitcoin/outputs?a=date,f(count()/count())&q=type(nulldata),time(2019-01)&aq=0:0 — calculates the percentage of nulldata outputs in January 2019 by day. The 0th condition (type(nulldata)) is applied to the 0th function (count()) and removed afterwards.

If you use the ?a= section, the default limit is 10000 instead of 10.

It's possible to export aggregated data to TSV or CSV format using &export=tsv or &export=csv accordingly. Example: https://api.blockchair.com/bitcoin/transactions?a=date,avg(fee_usd)&q=time(2019-01-01..2019-04-01)&export=tsv. Please note that data export is only available for aggregated data. If you need to export the whole table or its part, please use Database dumps.

Warning: the f({:expression}) special function, the ?aq= section, and TSV/CSV export are currently in alpha stage on our platform. Special function price({:ticker1}_{:ticker2}) can't be used within special function f({:expression}). There are some known issues when sorting if f({:expression}) is present. There are some known issues when applying the ?aq= section to inequality filters.

Fun example

The following requests return the same result:

https://api.blockchair.com/bitcoin/blocks?a=sum(reward)
https://api.blockchair.com/bitcoin/transactions?a=sum(output_total)&q=is_coinbase(true)
https://api.blockchair.com/bitcoin/outputs?a=sum(value)&q=is_from_coinbase(true)

Export data to TSV or CSV

Please use our Database dumps feature instead of the API (see https://blockchair.com/dumps for documentation)

Request cost formula for infinitables

Cost is calculated by summing up the following values:

The base cost for the table (see the table below): 2, 5, or 10
Applying a filter costs 1
Applying a sorting costs 0
Applying an offset costs 0
Applying an aggregation costs 10

Applying a limit over the default multiplies the summed cost by 1 + 0.01 * number_of_rows_over_the_default_limit. If the defaut limit is 10 and the base cost is 2, requesting 100 rows will cost 2 * (1 + 0.01 * 90) = 3.8.

Table descriptions

Further the documentation describes each of the supported tables. Each documentation section contains a general description, and a table listing the table columns (fields) in the following format:

Column	Type	Description	Q?	S?	A?	C?
Column name	Column type	Column description	Is it possible to filter by this column?	Is it possible to sort by this column?	Is it possible to group by this column?	Is it possible to apply aggregation functions (like `sum`) to this column?

The following marks are possible for the Q? column:

= — possible to use equalities only
* — possible to use both equalities and inequalities
⌘ — possible to use special format (applies to timestamp fields)
~ — possible to use the LIKE operator
^ — possible to use the STARTS WITH operator
*≈ — possible to use both equalities and inequalities, may return some results which are a bit out of the set range (this is used to swiftly search over the Ethereum blockchain that uses too long wei numbers for transfer amounts)

For the S?, A?, and C? columns it's either + (which means "yes") or nothing. ⌘ means some additional options may be available (in case of aggregation it may either mean additional fields like year are available, or in case of functions — only min and max are available).

There can also be synthetic columns which aren't shown in the response, but you can still filter or sort by them. If there are any, they will be listed in a separate table.

is_from_coinbase	boolean	Is it a coinbase transaction output?	`=`		`+`
is_spendable	null or boolean	Is it theoretically possible to spend this output? For `pubkey` and `multisig` outputs, the existence of the corresponding private key is tested, in that case `true` and `false` are the possible values depending on the result of the check. For `nulldata` outputs it is always `false`. For other types it is impossible to check trivially, in that case `null` is yielded.	`=`		`+`
is_spent	boolean	Has this output been spent? *(`spending_` fields below yield `null` if it is not)**	`=`		`+`
spending_block_id	null or int	Id of the block containing the spending transaction	`*`	`+`	`+`
spending_transaction_id	null or int	Internal Blockchair transaction id where the output was spent	`*`	`+`

Additional synthetic columns

Column	Type	Description	Q?	S?	A?	C?
script_bin	string `.*`	Text (UTF-8) representation of `script_hex`. Allows you to use the `LIKE` operator: `?q=script_bin(~hello)`. Filtering using the `LIKE` operator is performed for `nulldata` outputs only.	`~`

Notes:

increased efficiency method applies if querying transaction_id and spending_transaction_id columns using the equals operator
† — only for Bitcoin, Litecoin, Groestlcoin, and Bitcoin Testnet (SegWit data)
The default sorting — transaction_id DESC
spending_* columns yield null for outputs that haven't been spent yet
block_id for mempool transactions is -1
spending_block_id is -1 for outputs being spent by an unconfirmed transaction
This particular table is in beta test mode on our platform. It's possible to receive duplicate rows for outputs which have just been spent. Sometimes duplicates are removed automatically, but in that case the number of rows may be less than the set limit on the number of rows. There's an additional context key context.pre_rows which contains the number of rows that should've been returned before the duplicate removal process.

Output:

The addresses view contains the list of all addresses and their confirmed balances. Unlike other infinitables (blocks, transactions, outputs) this table isn't live, it's automatically updated every 5 minutes with new data, thus we classify it as a "view". data contains an array of database rows. Each row is in the following format:

Column	Type	Description	Q?	S?	A?	C?
address	string `[0-9a-zA-Z\-]*`	Bitcoin address or synthetic address
balance	int	Its confirmed balance	`*`	`+`		`+`

increased efficiency method applies if querying id and hash columns using the equals operator
Search by fields that contain values in wei (value_total, internal_value_total, generation, uncle_generation, fee_total, reward) may be with some inaccuracies
The difference between value_total and internal_value_total: e.g., a transaction itself sends 0 eth, but this transaction is a call of a contract that sends someone, let's say, 10 eth. Then value will be 0 eth, and internal_value - 10 eth

Column	Type	Description	Q?	S?	A?	C?
input_bin	string `.*`	Text (UTF-8) representation of input data. Allows you to use the `LIKE` operator: `?q=input_bin(~hello)`	`~`

Possible types (type) of transactions:

call — the transaction transfers the value, but there are no more calls (a simple ether sending, not in favor of a contract, or the call to a contract that does nothing)
create — create a new contract
call_tree — the transaction calls a contract that makes some other calls
create_tree — create a new contract that create contracts or starts making calls
synthetic_coinbase — a synthetic transaction for awarding a reward to the miner (block or uncle)

Notes:

increased efficiency method applies if querying id and hash columns using the equals operator
† — value is null for transactions in the mempool
‡ — value is null if type is synthetic_coinbase
Search by fields that contain values in wei (value_total, internal_value_total, generation, uncle_generation, fee_total, reward) may be with some inaccuracies
The difference between value_total and internal_value_total: e.g., a transaction itself sends 0 eth, but this transaction is a call of a contract that sends someone, let's say, 10 eth. Then value will be 0 eth, and internal_value - 10 eth
The default sorting — id DESC
block_id for mempool transactions is -1

`calls` table

Endpoint:

https://api.blockchair.com/{:eth_chain}/calls?{:query}

Where:

{:eth_chain} can only be ethereum or ethereum/testnet
{:query} is the query against the table (how to build a query)

Output:

Returns information about internal transaction calls. data contains an array of database rows. Each row is in the following format:

Column	Type	Description	Q?	S?	A?	C?
block_id	int	Block id containing a call	`*`	`+`	`+`
transaction_id	int	Transaction id containing the call	`*`	`+`
transaction_hash †	string `0x[0-9a-f]{64}`	Transaction hash (with 0x) containing the call	`=`
index	string	Call index within the transaction (tree-like, e.g., "0.8.1")	`=`	`+`
depth	int	Call depth within the call tree (starting at 0)	`*`	`+`
date	string `YYYY-MM-DD`	Date of the block that contains the call (UTC)			`⌘`
time	string `YYYY-MM-DD HH:ii:ss`	Time of the block that contains the call (UTC)	`⌘`	`+`
failed	bool	Failed call or not	`=`		`+`
fail_reason	string `.*` or null	If failed, then the failure description, if not, then `null`	`~`		`+`
type	string (enum)	The call type, one of the following values: `call`, `delegatecall`, `staticcall`, `callcode`, `selfdestruct`, `create`, `synthetic_coinbase`, `create2`	`=`	`+`	`+`
sender †	string `0x[0-9a-f]{40}`	Sender's address (with 0x)	`=`		`+`
recipient	string `0x[0-9a-f]{40}`	Recipient's address (with 0x)	`=`		`+`
child_call_count	int	Number of child calls	`*`	`+`		`+`
value	numeric string	Call value in wei, hereinafter `numeric string` - is a numeric string passed as a string, because wei-values do not fit into uint64	`*≈`	`+`		`+`
value_usd	float	Call value in USD	`*`	`+`		`+`
transferred	bool	Has ether been transferred? (`false` if `failed`, or if the type of transaction does not change the state, e.g., `staticcall`	`=`		`+`
input_hex †	string `[0-9a-f]*`	Input call data
output_hex †	string `[0-9a-f]*`	Output call data

Notes:

increased efficiency method applies if querying transction_id column using the equals operator
† — value is null if type is synthetic_coinbase
Search by fields that contain values in wei (value) may be with some inaccuracies
The default sorting is transaction_id DESC
sorting by index respects the tree structure (i.e. "0.2" comes before "0.11") instead of being alphabetical

`addresses` view

Endpoints:

https://api.blockchair.com/{:eth_chain}/addresses?{:query}

Where:

{:eth_chain} can only be: ethereum or ethereum/testnet
{:query} is the query against the table (how to build a query)

Output:

The addresses view contains the list of all addresses and their confirmed balances. Unlike other infinitables (blocks, transactions, outputs) this table isn't live, it's automatically updated every day with new data, thus we classify it as a "view". data contains an array of database rows. Each row is in the following format:

Column	Type	Description	Q?	S?	A?	C?
address	string `0x[0-9a-zA-Z\-]*`	Ethereum account or contract address
balance	numeric string	Its balance	`*`	`+`		`+`
nonce	int	Its nonce value	`*`	`+`		`+`
is_contract	boolean	Is it a contract (`true`) or an account (`false`)?	`=`		`+`

Notes:

the default sorting — balance DESC

`tokens` table (ERC-20)

Endpoint:

https://api.blockchair.com/ethereum/erc-20/tokens?{:query}
https://api.blockchair.com/ethereum/testnet/erc-20/tokens?{:query} (Goerli Testnet)

Where:

{:query} is the query against the table (how to build a query)

Output:

Returns information about ERC-20 tokens indexed by our engine. data contains an array of database rows. Each row is in the following format:

Column	Type	Description	Q?	S?	A?
address	string `0x[0-9a-f]{40}`	Address of the token contract	`=`
id	int	Internal Blockchair id of the token	`*`	`+`
date	string `YYYY-MM-DD`	Creation date			`⌘`
time	string `YYYY-MM-DD HH:ii:ss`	Creation timestamp	`⌘`	`+`
name	string `.*` (or an empty string)	Token name (e.g. `My New Token`)	`=`	`+`
symbol	string `.*` (or an empty string)	Token symbol (e.g. `MNT`)	`=`	`+`
decimals	int	Number of decimals	`=`	`+`
creating_block_id	int	Creating block height	`*`	`+`
creating_transaction_hash	string `0x[0-9a-f]{64}`	Creating transaction hash

Notes:

for the columns address, id increased efficiency when uploading one record is applied
there is no possibility to search over date column, use searching ?q=time(YYYY-MM-DD) instead
the default sort is id DESC
when using offset, it is reasonable to add to the filters the maximum block number (?q=block_id(..N)), since it is very likely that during the iteration new rows will be added to the table. For convenience, you can take the value of context.state from the first result of any query containing the number of the latest block at the query time and use this result later on.

Misc endpoints

Broadcasting transactions

Broadcast a transaction to the network

Endpoints:

https://api.blockchair.com/{:chain}/push/transaction (POST request)

Where:

{:chain} can be one of these: bitcoin, bitcoin-cash, ethereum, litecoin, bitcoin-sv, dogecoin, dash, groestlcoin, zcash, bitcoin/testnet, mixin
POST data should contain data parameter with raw transaction represented in hex (for Ethereum it should start with 0x)

Output:

If the transaction has been successfully broadcast to the network, API will return a JSON response (code 200) containing data array with transaction_hash key holding the hash of the received transaction. In case of any error (wrong transaction format, spending already spent outputs, etc.) API returns status code 400 and an error desription if available (descriptions aren't shown for ethereum and mixin).

Example of a successful response:

{
  "data": {
    "transaction_hash": "0e3e2357e806b6cdb1f70b54c3a3a17b6714ee1f0e68bebb44a74b1efd512098"
  },
  "context": {
  	"code": 200,
  	...
  }
}

Example of a response to an invalid transaction:

{
  "data": null,
  "context": {
    "code": 400,
    "error": "Invalid transaction. Error: 16: mandatory-script-verify-flag-failed (Signature must use SIGHASH_FORKID)"
    ...
  }
}

Example request:

> curl -v --data "data=01000000010000000000000000000000000000000000000000000000000000000000000000ffffffff0704ffff001d0104ffffffff0100f2052a0100000043410496b538e853519c726a2c91e61ec11600ae1390813a627c66fb8be7947be63c52da7589379515d4e0a604f8141781e62294721166bf621e73a82cbf2342c858eeac00000000" https://api.blockchair.com/bitcoin/push/transaction

Tip: for testing purpose it's possible to use GET request instead of POST like this: https://api.blockchair.com/bitcoin/push/transaction?data=0100000001000000000000000000000000...

Nodes

List of full network nodes

Endpoints:

https://api.blockchair.com/{:btc_chain}/nodes (agregated data on nodes + node list)
https://api.blockchair.com/nodes (agregated data on nodes for 8 networks at once)

Please note that the number of nodes is also available in the https://api.blockchair.com/stats and https://api.blockchair.com/{:btc_chain}/stats endpoints output.

Where:

{:btc_chain} can be one of these: bitcoin, bitcoin-cash, litecoin, bitcoin-sv, dogecoin, dash, groestlcoin, zcash

Output:

data contains an array of arrays:

data.nodes — the node list; the key is {:ip}:{:port}, each element contains version (node version), country (2 letter country code derived from the IP address based on geolocation), height (node reports this number as the best block number it has, flags (special field with node options)
data.count — total number of nodes
data.countries — number of nodes grouped by country codes
data.versions — number of nodes grouped by node version
data.heights — number of nodes grouped by their best block height

https://api.blockchair.com/nodes endpoint shows this data for 8 coins at once (bitcoin, bitcoin-cash, litecoin, bitcoin-sv, dogecoin, dash, groestlcoin, zcash), but it doesn't have the data.nodes array, i.e. there's only aggregated data.

State changes

Allows to query state changes caused by a block and potential state changes caused by mempool transactions in case they get confirmed.

Endpoints:

https://api.blockchair.com/{:chain}/state/changes/block/{:height} (state changes caused by a block)
https://api.blockchair.com/{:chain}/state/changes/mempool (potential state changes caused by mempool transactions)

Where:

{:chain} can be one of these: bitcoin, bitcoin-cash, litecoin, bitcoin-sv, dogecoin, dash, groestlcoin, zcash, bitcoin/testnet. The first endpoint also supports ethereum
{:height} is the block height (integer value), also known as block id

Output:

The response contains an array where the keys are addresses which were affected by the block (or the mempool), and the values are balance changes.

Note: values are returned as strings for Ethereum.

No iteration required, this endpoint outputs all state changes at once.

The block in this example was the first Bitcoin block which contained a non-coinbase transaction. We can see the coinbase reward here (50 BTC) sent to the miner, and two state changes caused by a 10 BTC transaction.

Example usage:

This endpoint may be useful if you need to track balance changes for a lot of addresses — you can simply track state changes and find the needed addresses there instead of constantly retrieving information about the balances. Here's an example logic for an application watching for Bitcoin transactions incoming/outgoing to/from 1 million addresses:

latest_known_block_height = 0
addresses = [1Abc, 1Efg, 1Hij, ...]
while (true)
    api_response = api_request('https://api.blockchair.com/bitcoin/state/changes/mempool')
    if any of api_response.data keys are in the addresses array
        print 'Found new transaction in the mempool'
    if latest_known_block_height < api_response.context.state // A new block has been mined (context.state always yields the latest block number)
        latest_known_block_height = api_response.context.state
        api_response_block = api_request('https://api.blockchair.com/bitcoin/state/changes/block/{:api_response.context.state}')
        if any of api_response_block.data keys are in the addresses array
            print 'Found new transaction in the latest block'
    sleep(10) // The mempool data is cached for 10 seconds on our servers by default

Note that this example doesn't account for cases like new multiple blocks have been found while you were requesting the latest one, etc. See this example as a possible workaround: https://github.com/Blockchair/Blockchair.Support/pull/207/files

Request cost formula:

5 for changes caused by a block, 10 for changes caused by mempool transactions.

Available block ranges

As Blockchair doesn't store historical data for some blockchains (at this moment this applies to Ripple and Stellar only) it may be useful to know which blocks can be queried.

Endpoint:

https://api.blockchair.com/range

Output:

The response contains an array where the keys are blockchains, and the values are arrays containing:

blockchain_first_entry — first block (or ledger) id on the blockchain
blockchain_first_entry_date — its date
blockchair_first_entry — first block id Blockchair processes
blockchair_first_entry_date — its date
is_full — whether we have the full history for this blockchain

Release monitor

This endpoint returns the list of latest software (core clients) releases for blockchains we support. This may be useful for those who want to track blockchain development, new features, and hard forks (especially this is useful for multi-currency blockchain software — wallets or exchanges — developers). Never miss a BSV hard fork anymore!

Endpoint:

https://api.blockchair.com/tools/releases

Possible options:

?chain={:chain} displays latest releases for {:chain} only

Output:

data contains an array of latest releases sorted by time for all chains we support (or for a specific chain if ?chain is set). Each element is an array with the following elements:

chain — chain id
version — tag name
time — release publish time (UTC)
link — link to this release on GitHub

context has two special fields:

latest_update — latest update time (UTC)
supported_chains — array of chains monitored with their chain ids and software names

Privacy-o-meter

Introduction

While Bitcoin is considered to be a privacy-oriented system, the blockchain is open to analyze by anyone, and there are numerous transaction tracing tools like Chainalysis, Coinfirm, Elliptic, CipherTrace, and Crystal. They're all not free, and Bitcoin users rarely have a chance to see how deep the rabbit hole goes. We start with a simple transaction scoring tool, and will soon expand this even further. We'll provide this service for free as we hope it'd help Bitcoin users to take some of their privacy back.

Transaction tracing is quite an easy task on the Bitcoin blockchain due to the following reasons:

Most users aren't concerned enough about their privacy and make rookie mistakes like sending round BTC amounts
Wallet software developers mostly don't care about user privacy. Taking the previous example in context, there are no warnings if user tries to send a round amount.
There are multiple wallets with different transaction processing rules making it possible to figure out what software type given user uses
Bitcoin blockchain is congested due to refusal to properly scale — that makes using mixers very expensive and cumbersome
While there are multiple protocols allowing more secure ways to transact (like shielded transactions on Zcash), these are not implemented in Bitcoin out of fears of changing the protocol
Bitcoin has multiple standard script types, their number has been recently increased with the activation of SegWit, and will increase further with new constructs built on top of SegWit

Here's a good overview of some basic heuristics: https://en.bitcoin.it/wiki/Privacy — we use most of them and introduce many new ones. The full list of heuristics we're using is available below.

At the moment, Privacy-o-meter is available for Bitcoin only, but we'll soon expand it to other UTXO-based coins, and then to all the others we support.

A couple of examples of transactions with bad and good privacy scores

Take this transaction as an example: https://blockchair.com/bitcoin/transaction/116bd19a3ec5f210ce72043115a4d5d3ef08f7556829c4feac8d89de3195ea4e

It has 2 inputs and 2 outputs:

Input addresses	Input values		Output values	Output addresses
bc1qj9p0huddhg5pzccur…	0.96350000 BTC	⟾	1.00000000 BTC	3EgAFC6FKojYUu53…
bc1qrpfxyvdc3fqmyux54…	281.65022105 BTC	⟾	281.61332105 BTC	bc1qva7utdxd6easlj…

And also the following characteristics:

Uses SegWit: yes
Lock time: 0
Version: 1

An analyst will be able to gather lots of metadata looking at this transaction:

First output has a round amount of 1 bitcoin
First output has a P2SH address type while both inputs and the second output are P2WSH
Given (1) and (2) it can be assumed that 3EgAFC6FKojYUu53… is the recipient, and bc1qva7utdxd6easlj… is the change address. Thus we can say that bc1qj9p0huddhg5pzccur…, bc1qrpfxyvdc3fqmyux54…, and bc1qva7utdxd6easlj… can be clusterized as belonging to one entity
There's a discrepancy: if the sender wanted to send just 1 bitcoin, there's no need for the first output to be in the transaction, the second would be more than sufficient. That shows that the sender is probably using a non-standard wallet software
The transaction's lock time value is 0 and the sender uses SegWit-copmatible software that generates version 1 transactions. That and (4) can be used to single out the sender's wallet software

Our system gives this transaction the score of 0 as it's too clear which output is the recipient and which is the change.

One important point: it's not probable, but still possible that this partiular transaction's sender tries to confuse forensics software and all the conclusions are incorrect. So, basically, if you're trying to increase your privacy level knowing how to do that, and getting the 0 score, you're probably doing that right.

Let's take another transaction to show some contrast: https://blockchair.com/bitcoin/transaction/24a517dd2ffbb3a290eeee75d6dea2c62df7ebcd6f898b703b70dc031baa8a18

It has 1 input and 2 outputs:

Input addresses	Input values		Output values	Output addresses
12CBjcNtRU7c795neLC…	0.01006987 BTC	⟾	0.00344481 BTC	199eZE5j4shSU7D9…
			0.00640487 BTC	1CGL5micNcJbMaV…

This is a relatively rare example of a transaction getting a 100 score. It's not possible to distinguish the recipient from the change address just by analyzing this transaction.

Heuristics we use:

Heuristic key	Heuristic name	Description and notes	Affects clusterization?	Example transaction	API example
Most common heuristics	♠	♠	♠	♠	♠
`inputs`	Co-spending	Unless it's a CoinJoin transaction it's safe to assume that all input addresses belong to one person	`+`	👉	👉
`script_types`	Script types	If all inputs has the same type, and exactly one of the outputs is not of the same type — this output can be considered as the recipient	`+`	👉	👉
`p2sh_types`	P2SH multisig types	If all inputs are `m of n` multisig P2SH, and all outputs are multisig P2SH, but exactly one of the outputs has another `m` of `n` structure — this output can be considered as the recipient	`+`	👉	👉
`p2wsh_types`	P2WSH multisig types	If all inputs are `m of n` multisig P2WSH, and all outputs are multisig P2WSH, but exactly one of the outputs has another `m` of `n` structure — this output can be considered as the recipient	`+`	👉	👉
`round_value`	Round value	If one of the outputs has a round value (like exactly 1 BTC) — this output can be considered as the recipient	`+`	👉	👉
`recipient_by_value`	Recipient by bigger value	If the recipient is the smaller output, there's no point in having some of the inputs	`+`	👉	👉
`t1-2_bigger_value_25`	Output value x25	One of the two outputs is 25 times bigger than the other meaning that it's potentially the change output	`+`	👉	👉
`t1-2_bigger_value_100`	Output value x100	- 〃 - 〃 - 100 times bigger	`+`	👉	👉
`t1-2_bigger_value_250`	Output value x250	- 〃 - 〃 - 250 times bigger	`+`	👉	👉
`t1-2_bigger_value_1000`	Output value x1000	- 〃 - 〃 - 1000 times bigger	`+`	👉	👉
`coinbase_known`	Known miner	The recipient is the known miner		👉	👉
`coinbase_unknown`	Unknown miner	The recipient is an unknown miner		👉	👉
`coinjoin`	Coinjoin	This is a CoinJoin transaction. This cancels all other heuristics.	`+`	👉	👉
`round_fee`	Round fee	The transaction has a round fee amount, the sender is probably using some specific software		👉	👉
`rare_fingerprint`	Rare fingerprint	This transaction has quite unique technical characteristics		👉	👉
Specific order of inputs and outputs	♠	♠	♠	♠	♠
`asc_output_values`	Ascending output values	For transaction with more than 5 outputs — they are ordered by value ascending — that may due to some specific software usage		👉	👉
`desc_output_values`	Descending output values	Same, but in descending order. Generally, all descending patterns are more rare than ascending.		👉	👉
`asc_output_addresses`	Ascending output addresses	Same, but this time it's addresses sorted in alphabetical order		👉	👉
`desc_output_addresses`	Descending output addresses	- 〃 - 〃 - (Very rare)		👉	👉
`asc_input_values`	Ascending input values	- 〃 - 〃 - Same, but for inputs		👉	👉
`desc_input_values`	Descending input values	- 〃 - 〃 -		👉	👉
`asc_input_addresses`	Ascending input addresses	- 〃 - 〃 - (Very rare)		👉	👉
`desc_input_addresses`	Descending input addresses	- 〃 - 〃 - (Very rare)		👉	👉
`asc_input_timestamps`	Ascending input timestamps	- 〃 - 〃 - Same, inputs are sorted by age		👉	👉
`desc_input_timestamps`	Descending input timestamps	- 〃 - 〃 -		👉	👉
`asc_output_values_except_first`	Ascending output values except first	All outputs are sorted by value ascending except for the first one, that may mean that the first output is the change address. But this is a quite vague heuristic, thus we don't use it in clusterization.		👉	👉
`asc_output_values_except_last`	Ascending output values except last	- 〃 - 〃 -		👉	👉
`asc_output_addresses_except_first`	Ascending output addresses except first	- 〃 - 〃 -		👉	👉
`asc_output_addresses_except_last`	Ascending output addresses except last	- 〃 - 〃 -		👉	👉

Reuse of the same address	♠	♠	♠	♠	♠
`simple_reuse_1-2`	Address reuse	The sender uses the same address for receiving and for change		👉	👉
`simple_reuse_N-2`	Address reuse	The sender uses the same address for receiving and for change		👉	👉
`simple_reuse_1-N`	Address reuse	The sender (probably an exchange) uses the same address for receiving and for change		👉	👉
`simple_reuse_same_address_in_inputs`	Same address in inputs	There's multiple occurences of the same address in inputs		👉	👉
Sweeps	♠	♠	♠	♠	♠
`sweep_1-1`	Sweep (1-1)	The sender uses the "send everything" option to either pay someone (e.g. an exchange) or just moving the funds to another wallet (1 input)		👉	👉
`sweep_1-1_to_another_type`	Sweep to another type (1-1)	- 〃 - 〃 - Same, but the outputs is of another type. The sender is either paying someone or moving the funds to a new wallet type (1 input)		👉	👉
`sweep_N-1`	Sweep	- 〃 - 〃 - Same, but with multiple inputs		👉	👉
`sweep_N-1_to_another_type`	Sweep to another type	- 〃 - 〃 - Same, but to another address type		👉	👉
Discrepancies	♠	♠	♠	♠	♠
`discrepancy_unnecessary_inputs`	Discrepancy: unnecessary input	The smaller input is unnecessary, as whichever of the outputs is the recipient, there's no need to include that input		👉	👉
`discrepancy_input_types`	Discrepancy: various input types	The inputs are of different types. That means the sender is probably using the software allowing to create the same address type for the change as the recipient has, trying to circumvent the `script_types` heuristic		👉	👉
`discrepancy_script_types_and_round_value`	Discrepancy between Script types and Round value	`script_types` and `round_value` heuristics yield different results	`+`	👉	👉
`discrepancy_script_types_and_recipient_by_value`	Discrepancy between Script types and Recipient by value	`script_types` and `recipient by value` heuristics yield different results	`+`	👉	👉
`discrepancy_round_value_and_recipient_by_value`	Discrepancy between Round value and Recipient by value	`round_value` and `recipient by value` heuristics yield different results	`+`	👉	👉
`discrepancy_p2sh_various_input_types`	Discrepancy: various P2SH input types	The P2SH input types are different (e.g. one is 2-of-2 multisig, and the other is 2-of-3). Very rare.		👉	👉
`discrepancy_p2wsh_various_input_types`	Discrepancy: various P2WSH input types	- 〃 - 〃 - Same, but for P2WSH		N/A	N/A
`discrepancy_same_address_in_outputs`	Discrepancy: output address duplicates	There are outputs with the same address — that makes no economical sense		👉	👉
`discrepancy_no_output_of_the_same_type_as_inputs`	Discrepancy: no output of the same type as inputs	Probably the sender uses software generating the same change address type as the recipient address has		👉	👉

Possible transaction types are:

Type code	Description
`CB`	Coinbase transaction
`N1`	Transaction with just 1 output (either a sweep to another address by the same owner, or a transfer using a "send everything I have" option)
`N2`	Transaction with 2 outputs — most common in wallets — where one of the outputs is the recipient, and the other one is the change address
`NN`	Transaction with more than 2 outputs — most common in exchanges and services that use payout batching

Transaction fingerprint:

Property	Possible values	Description
`lock_time`	`0`, `rare`, `block_id`, `big_value`, `timestamp`	Depending on wallet software, `lock_time` property can either be `0`, or a block height, or some timestamp. In rare cases it's some other value (`rare` or `big_value`)
`version`	`1`, `2`, `unknown`	Versions `1` and `2` are distributed almost equally these days
`has_witness`	`true`, `false`	SegWit usage is a distinctive property — there are wallets and exchanges who are known to be using or not using SegWit

API endpoints

Transaction score

Endpoints:

https://api.blockchair.com/{:chain}/dashboards/transaction/{:hash}₀?privacy-o-meter=true
https://api.blockchair.com/{:chain}/dashboards/transactions/{:hash}₀,...,{:hash}ᵩ?privacy-o-meter=true (up to 10 transactions, comma-separated)

Output:

See the transaction dashboard for general transaction info: 👉
privacy-o-meter array with scoring data:
- type — transaction type (CB, N1, N2, or NN)
- fingerprint — transaction properties allowing to understand what software the sender uses
- is_finalized — shows whether the transaction has the final score — true if all outputs are spent, false otherwise (nulldata and other non-spendable outputs are considered as spent)
- heuristics — array of heuristic keys applicable for the transaction
- clusterized — array of addresses potentially belonging to one entity based on the applicable heuristics
- score — transaction privacy score where 0 is the worst score, and 100 is the best score

News aggregator

Not only Blockchair API provides you with blockchain data, but also with some crypto news to integrate into your app. We're aggregating data from more than 60 news outlets in 14 languages, populating over 35,000 headlines into our database a month.

News list

Endpoint:

https://api.blockchair.com/news?{:query}

Where:

{:query} is the query against the table (how to build a query)

This endpoint acts like an Infinitable meaning you can perform SQL-like queries: filter sort, and aggregate news articles.

data contains an array of database rows. Each row is in the following format:

Column	Type	Description	Q?	S?
title	`string`	Headline	`~`
source	`string` (domain name)	Source (domain name)	`=`
language	`string [a-z]{2}`	Supported languages: `ar`, `de`, `en`, `es`, `fa`, `fr`, `it`, `jp`, `ko`, `nl`, `pt`, `ru`, `tr`, `zh`	`=`
link	`string` (URL)	URL to the article on the source website
link_amp	`string` (URL)	URL to the AMP (Accelerated Mobile Pages) article on the source website or `false` if AMP is not available. `null` if it hasn't been processed yet (usually it takes under a few seconds)
link_iframable	`boolean`	`true` if the page could be put into an iframe (`false` otherwise). Note that there's no guarantee this value is valid as the source can change its policy after the page was crawled! `null` if it hasn't been processed yet (usually it takes under a few seconds)
time	`YYYY-MM-DD HH:ii:ss`	Timestamp	`⌘`	`+`
tags	`string` (comma-separated list)	Comma-separated list of tags by the publisher
description	`string`	Short description	`~`
hash	`[0-9a-f]{10}`	Internal Blockchair hash (unique id)	`=`
file	`string`	Internal Blockchair article name
permalink	`string` (URL)	URL to the article on Blockchair.com

Default sorting is by time descending.
