tastytrade is an options-focused brokerage offering a public Open API that provides full read and write access to real-time account data, positions, balances, transaction history, market data, option chains, and order execution across equities, options, futures, and crypto. The API uses REST over HTTPS with JSON payloads for synchronous operations and WebSocket connections (DXLink for market data, dedicated account streamer for real-time account updates). OAuth 2.0 and session-token authentication are both supported, with a safe sandbox environment for development and testing.
