xt-net

XT.Net Conventions

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

Client Setup Pattern

using XT.Net;
using XT.Net.Clients;

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

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

Result Pattern

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

var ticker = await restClient.SpotApi.ExchangeData.GetTickersAsync("eth_usdt");
if (!ticker.Success) { Console.WriteLine(ticker.Error); return; }
var first = ticker.Data.First();

API Surface

• restClient.SpotApi.{ExchangeData|Account|Trading}
• restClient.UsdtFuturesApi.{ExchangeData|Account|Trading}
• restClient.CoinFuturesApi.{ExchangeData|Account|Trading}
• socketClient.SpotApi
• socketClient.FuturesApi

Do not generate socketClient.UsdtFuturesApi or socketClient.CoinFuturesApi; futures sockets are under FuturesApi.

WebSocket Pattern

var socketClient = new XTSocketClient();
var sub = await socketClient.SpotApi.SubscribeToTickerUpdatesAsync(
    "eth_usdt",
    update => Console.WriteLine(update.Data.LastPrice));
if (!sub.Success) { Console.WriteLine(sub.Error); return; }

await socketClient.UnsubscribeAsync(sub.Data);

Private spot streams need restClient.SpotApi.Account.GetWebsocketTokenAsync(). Private futures streams need restClient.UsdtFuturesApi.Account.GetListenKeyAsync().

Multi-Exchange Code

For exchange-agnostic code, use CryptoExchange.Net.SharedApis:

using CryptoExchange.Net.SharedApis;

var shared = new XTRestClient().SpotApi.SharedApi;
var ticker = await shared.GetTickerAsync(
    new GetTickerRequest(new SharedSymbol(TradingMode.Spot, "BTC", "USDT")));

Hard Rules

• Never write raw HttpClient XT endpoint calls.
• Never use .Result or .Wait(); use await.
• Never instantiate clients per request; reuse or use DI.
• Never skip checking WebCallResult.Success.
• Always use XTCredentials("key", "secret"), not generic ApiCredentials.
• Always store WebSocket subscriptions and unsubscribe on shutdown.
• Always inspect XT.Net/Interfaces/Clients/** before generating methods not in the map.
