How to use

Basic request:

// Get the ETH/USD ticker via rest request
var restClient = new CryptoComRestClient();
var tickerResult = await restClient.ExchangeApi.ExchangeData.GetTickerAsync("ETH_USD");
var lastPrice = tickerResult.Data.LastPrice;

Place order:

var restClient = new CryptoComRestClient(opts => {
	opts.ApiCredentials = new CryptoComCredentials("APIKEY", "APISECRET");
});

// Place Limit order to buy 0.1 ETH at 2000
var orderResult = await restClient.ExchangeApi.Trading.PlaceOrderAsync(
    "ETH_USDT",
    OrderSide.Buy,
    OrderType.Limit,
    0.1m,
    price: 2000);

WebSocket subscription:

// Subscribe to ETH/USD ticker updates via the websocket API
var socketClient = new CryptoComSocketClient();
var tickerSubscriptionResult = socketClient.ExchangeApi.SubscribeToTickerUpdatesAsync("ETH_USD", (update) => 
{
  var lastPrice = update.Data.LastPrice;
});

For information on the clients, dependency injection, response processing and more see the documentation, or have a look at the examples here or here.

AI / LLM documentation

CryptoCom.Net includes AI-oriented documentation and examples for code generation tools:

GitHub Copilot and Cursor instructions are also provided in .github/copilot-instructions.md and .cursor/rules/cryptocom-net.mdc; both point back to the root AI context files.

CryptoExchange.Net

CryptoCom.Net is based on the CryptoExchange.Net base library. Other exchange API implementations based on the CryptoExchange.Net base library are available and follow the same logic.

CryptoExchange.Net also allows for easy access to different exchange API's.
