Getting Started with OKX.Net
REST API Usage Example
// Retrieve ETH/USDT ticker information via REST API
var restClient = new OKXRestClient();
var tickerResult = await restClient.UnifiedApi.ExchangeData.GetTickerAsync("ETH-USDT");
var lastPrice = tickerResult.Data.LastPrice;WebSocket API Implementation
// Subscribe to real-time ETH/USDT ticker updates
var socketClient = new OKXSocketClient();
var tickerSubscriptionResult = socketClient.UnifiedApi.ExchangeData.SubscribeToTickerUpdatesAsync("ETH-USDT", (update) =>
{
var lastPrice = update.Data.LastPrice;
});European Server Configuration
European clients should configure the environment accordingly:
// Dependency Injection configuration
services.AddOKX(options =>
{
options.Environment = OKXEnvironment.Europe;
});
// Direct client construction
var client = new OKXRestClient(options =>
{
options.Environment = OKXEnvironment.Europe;
