How to use

REST Endpoints

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

Websocket streams

// Subscribe to ETH/USDT ticker updates via the websocket API
var socketClient = new OKXSocketClient();
var tickerSubscriptionResult = socketClient.UnifiedApi.ExchangeData.SubscribeToTickerUpdatesAsync("ETH-USDT", (update) =>
{
	var lastPrice = update.Data.LastPrice;
});

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

CryptoExchange.Net

OKX.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.
