Experimental: A CoinGecko integration is currently in testing on branch
coingecko-integration. It addscg_list(),cg_listings(),cg_history(), andcg_info()— CMC-column-compatible companions that pull from CoinGecko, no API key required. Please install and play around with it, and open an issue if anything breaks. Install with:# install.packages("remotes") remotes::install_github("sstoeckl/crypto2@coingecko-integration")CoinGecko's free tier exposes only active coins; the package warns when delisted-coin retrieval is impossible. Build a survivorship-bias-free archive by snapshotting periodically (daily/weekly) from your own cronjob.
Historical Cryptocurrency Prices for Active and Delisted Tokens!
This is a modification of the original crypto package by jesse
vent. It is entirely set up to use
means from the tidyverse and provides tibbles with all data
available via the web-api of
coinmarketcap.com. It does not require
an API key but in turn only provides information that is also available
through the website of
coinmarketcap.com.
It allows the user to retrieve
crypto_listings()a list of all coins that were historically listed on CMC (main dataset to avoid delisting bias) according to the CMC API documentationcrypto_list()a list of all coins that are listed as either being active, delisted or untracked according to the CMC API documentationcrypto_info()a list of all information available for all available coins according to the CMC API documentationcrypto_history()the most powerful function of this package that allows to download the entire available history for all coins covered by CMC according to the CMC API documentationcrypto_global_quotes()a dataset of historical global crypto currency market metrics to the CMC API documentationfiat_list()a mapping of all fiat currencies (plus precious metals) available via the CMC WEB APIexchange_list()a list of all exchanges available as either being active, delisted or untracked according to the CMC API documentationexchange_info()a list of all information available for all given exchanges according to the CMC API documentation
Update
Version 2.0.2/2.0.3/2.0.4/2.0.5 (September 2025)
Slight change in api output broke crypto_info() (new additional
column). Fixed.
Version 2.0.1 (July 2024)
Slight change in api output broke crypto_info(). Fixed.
Version 2.0.0 (May 2024)
After a major change in the api structure of coinmarketcap.com, the package had to be rewritten. As a result, many functions had to be rewritten, because data was not available any more in a similar format or with similar accuracy. Unfortunately, this will potentially break many users implementations. Here is a detailed list of changes:
crypto_list()has been modified and delivers the same data as before.exchange_list()has been modified and delivers the same data as before.fiat_list()has been modified and no longer delivers all available currencies and precious metals (therefore only USD and Bitcoin are available any more).crypto_listings()needed to be modified, as multiple base currencies are not available any more. Also some of the fields downloaded from CMC might have changed. It still retrieves the latest listings, the new listings as well as historical listings. The fields returned have somewhat slightly changed. Also, no sorting is available any more, so if you want to download the top x CCs by market cap, you have to download all CCs and then sort them in R.crypto_info()has been modified, as the data structure has changed. The fields returned have somewhat slightly changed.crypto_history()has been modified. It still retrieves all the OHLC history of all the coins, but is slower due to an increased number of necessary api calls. The number of available intervals is strongly limited, but hourly and daily data is still available. Currently only USD and BTC are available as quote currencies through this library.crypto_global_quotes()has been modified. It still produces a clear picture of the global market, but the data structure has somewhat slightly changed.
Version 1.4.7
Since version 1.4.6 I have added the possibility to “sort” the
historical crypto_listings() in _asc_ending or _desc_ending order
(“sort_dir”) to allow for the possibility to download only the top x
crypto currencies using “limit” based on the requested sort (not
available for “new” sorting). Also corrected some problems when sourcing
lists that now do not have the “last_historical_data” field available
any more.
Since version 1.4.5 I have added a new function crypto_global_quotes()
which retrieves global aggregate market statistics for CMC. There also
were some bugs fixed.
Since version 1.4.4 a new function crypto_listings() was introduced
that retrieves new/latest/historical listings and listing information at
CMC. Additionally some aspects of the other functions have been
reworked. We noticed that finalWait = TRUE does not seem to be
necessary at the moment, as well as sleep can be set to ‘0’ seconds.
If you experience strange behavior this might be due to the the api
sending back strange (old) results. In this case let sleep = 60 (the
default) and finalWait = TRUE (the default).
Since version 1.4.0 the package has been reworked to retrieve as many
assets as possible with one api call, as there is a new “feature”
introduced by CMC to send back the initially requested data for each api
call within 60 seconds. So one needs to wait 60s before calling the api
again. Additionally, since version v1.4.3 the package allows for a data
interval larger than daily (e.g. ‘2d’ or ‘7d’ or ‘weekly’)
Installation
You can install crypto2 from CRAN with
install.packages("crypto2")
or directly from github with:
# install.packages("devtools")
devtools::install_github("sstoeckl/crypto2")
Package Contribution
The package provides API free and efficient access to all information
from https://coinmarketcap.com that is also available through their
website. It uses a variety of modification and web-scraping tools from
the tidyverse (especially purrr).
As this provides access not only to active coins but also to those that have now been delisted and also those that are categorized as untracked, including historical pricing information, this package provides a valid basis for any Asset Pricing Studies based on crypto currencies that require survivorship-bias-free information. In addition to that, the package maintainer is currently working on also providing delisting returns (similarly to CRSP for stocks) to also eliminate the delisting bias.
Package Usage
First we load the crypto2-package and download the set of active coins
from https://coinmarketcap.com (additionally one could load delisted
coins with only_Active=FALSE as well as untracked coins with
add_untracked=TRUE).
library(crypto2)
library(dplyr)

# List all active coins
coins <- crypto_list(only_active=TRUE)
Next we download information on the first three coins from that list.

Alternatively, we could determine the price of these coins in other
currencies. A list of such currencies is available as fiat_list()
$ \text{r} \text{fiats} <- \text{fiat\_list}() \text{fiats} #> # \text{A} \text{tibble}: 1 \times 4 #> \text{id} \text{name} \text{sign} \text{symbol} #> <\text{int}> <\text{chr}> <\text{chr}> <\text{chr}> #> 1 2781 \text{United} \text{States} \text{Dollar} $ \text{USD} $
So we download the time series again depicting prices in terms of
Bitcoin and Euro (note that multiple currencies can be given to
convert, separated by “,”).

We can use those quotes to plot information on the aggregate market capitalization:
all_quotes %>% select(timestamp, USD_total_market_cap, USD_altcoin_market_cap) %>%
tidyr::pivot_longer(cols = 2:3, names_to = "Market Cap", values_to = "bn. USD") %>%
tidyr::separate(`Market Cap`,into = c("Currency","Type","Market","Cap")) %>%
dplyr::mutate(`bn. USD`=`bn. USD`/1000000000) %>%
ggplot2::ggplot(ggplot2::aes(x=timestamp,y=`bn. USD`,color=Type)) + ggplot2::geom_line() +
ggplot2::labs(title="Market capitalization in bn USD", subtitle="CoinMarketCap.com")

and then download information on “binance” and “bittrex”:
$ \text{r} \text{ex\_info} <- \text{exchange\_info}(\text{exchanges} %>% \text{filter}(\text{slug} %\text{in}% \text{c}('\text{binance}','\text{kraken}')), \text{finalWait}=\text{FALSE}) #> ❯ \text{Scraping} \text{crypto} \text{info} #> #> ❯ \text{Processing} \text{exchange} \text{info} #> \text{ex\_info} #> # \text{A} \text{tibble}: 2 \times 21 #> \text{id} \text{name} \text{slug} \text{logo} \text{description} \text{date\_launched} \text{notice} \text{is\_hidden} \text{status} #> <\text{int}> <\text{chr}> <\text{chr}> <\text{chr}> <\text{chr}> <\text{date}> <\text{chr}> <\text{int}> <\text{chr}> #> 1 24 \text{Kraken} \text{kraken} \text{https}… "## \text{What} \text{I}… 2011-07-28 "" 0 \text{active} #> 2 270 \text{Binance} \text{binance} \text{https}… "## \text{What} \text{I}… 2017-07-14 "" 0 \text{active} #> # ℹ 12 \text{more} \text{variables}: \text{type} <\text{chr}>, \text{maker\_fee} <\text{dbl}>, \text{taker\_fee} <\text{dbl}>, #> # \text{platform\_id} <\text{int}>, \text{dex\_status} <\text{int}>, \text{wallet\_source\_status} <\text{int}>, #> # \text{alert\_type} <\text{int}>, \text{alert\_link} <\text{chr}>, \text{tags} <\text{lgl}>, \text{countries} <\text{lgl}>, #> # \text{fiats} <\text{list}>, \text{urls} <\text{list}> $
Then we can access information on the fee structure,
ex_info %>% select(contains("fee"))
#> # A tibble: 2 × 2
#> maker_fee taker_fee
#> <dbl> <dbl>
#> 1 0.02 0.05
#> 2 0.02 0.04
or the fiat currencies allowed:
$ \text{r} \text{ex\_info} %>% \text{select}(\text{slug},\text{fiats}) %>% \text{tidyr}::\text{unnest}(\text{fiats}) #> # \text{A} \text{tibble}: 95 \times 2 #> \text{slug} \text{fiats} #> <\text{chr}> <\text{chr}> #> 1 \text{kraken} \text{USD} #> 2 \text{kraken} \text{EUR} #> 3 \text{kraken} \text{GBP} #> 4 \text{kraken} \text{CHF} #> 5 \text{kraken} \text{AUD} #> 6 \text{kraken} \text{CAD} #> 7 \text{binance} \text{ARS} #> 8 \text{binance} \text{AUD} #> 9 \text{binance} \text{BRL} #> 10 \text{binance} \text{CHF} #> # ℹ 85 \text{more} \text{rows} $
