Quick Start

                
using Tradier;
using Tradier.Services;

// Create authentication with your API key
var auth = new TradierAuthentication("YOUR_API_KEY");

// Create client (use TradierSandboxClient for paper trading)
var client = new TradierSandboxClient(auth);

// Use the services
var marketData = new MarketDataService(client);
var quotes = await marketData.GetQuotes(true, "AAPL", "MSFT", "GOOGL");
