Mexc.Net Conventions

This codebase uses Mexc.Net for MEXC cryptocurrency exchange access. Do not write raw HttpClient calls to MEXC endpoints.

Client Setup Pattern

using Mexc.Net;
using Mexc.Net.Clients;

var restClient = new MexcRestClient(options =>
{
    options.ApiCredentials = new MexcCredentials("API_KEY", "API_SECRET");
});

For public market data only, no credentials are needed: new MexcRestClient().

Result Pattern

All methods return WebCallResult<T> or WebCallResult for REST, and CallResult<T> for WebSocket subscriptions. Always check .Success before reading .Data:

var ticker = await restClient.SpotApi.ExchangeData.GetTickerAsync("BTCUSDT");
if (!ticker.Success) { /* ticker.Error */ return; }
var price = ticker.Data.LastPrice;

API Surface

• restClient.SpotApi.{ExchangeData|Account|Trading|SubAccount}
• restClient.FuturesApi.{ExchangeData|Account|Trading}
• socketClient.SpotApi for spot WebSocket streams
• socketClient.FuturesApi for futures WebSocket streams
• SpotApi.SharedClient and FuturesApi.SharedClient for CryptoExchange.Net.SharedApis

Symbol Formats

• Spot: BTCUSDT
• Futures: BTC_USDT

Order Placement

Let the library omit/generate clientOrderId. Do not pass a custom one unless required for an existing operational flow:

var order = await restClient.SpotApi.Trading.PlaceOrderAsync(
    "BTCUSDT",
    OrderSide.Buy,
    OrderType.Limit,
    quantity: 0.001m,
    price: 50000m);

WebSocket Pattern

var socketClient = new MexcSocketClient();
var sub = await socketClient.SpotApi.SubscribeToMiniTickerUpdatesAsync(
    "BTCUSDT",
    update => { /* update.Data.LastPrice */ });
if (!sub.Success) { /* sub.Error */ return; }

await socketClient.UnsubscribeAsync(sub.Data);

Spot private streams require a listen key:

var listenKey = await restClient.SpotApi.Account.StartUserStreamAsync();
if (!listenKey.Success) return;

var orderSub = await socketClient.SpotApi.SubscribeToOrderUpdatesAsync(
    listenKey.Data,
    update => { /* update.Data.Status */ });
