How to use

Basic request:

// Get the ETH/USDT ticker via rest request
var restClient = new MexcRestClient();
var tickerResult = await restClient.SpotApi.ExchangeData.GetTickerAsync("ETHUSDT");
var lastPrice = tickerResult.Data.LastPrice;

Place order:

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

// Place Limit order to buy 0.1 ETH at 2000
var orderResult = await restClient.SpotApi.Trading.PlaceOrderAsync(
    "ETHUSDT",
    OrderSide.Buy,
    OrderType.Limit,
    quantity: 10,
    price: 2000
    );

WebSocket subscription:

// Subscribe to ETH/USDT ticker updates via the websocket API
var socketClient = new MexcSocketClient();
var tickerSubscriptionResult = socketClient.SpotApi.SubscribeToMiniTickerUpdatesAsync("ETHUSDT", (update) => 
{
  var lastPrice = update.Data.LastPrice;
});

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

AI / LLM documentation

Mexc.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/mexc-net.mdc; both point back to the root AI context files.

CryptoExchange.Net

Mexc.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.
