The Yellow.pro platform provides REST and WebSocket APIs for authentication, trading, account management, and market data. There are two base URLs:
  • Authentication API — wallet-based authentication, JWT tokens, and session management
  • Trading API — trading, positions, transfers, market data, and the WebSocket stream
New here? Start with Getting Started with API to authenticate and obtain your API keys.

​
Base URLs

All examples in these docs use the production hosts above. Market data endpoints are served from the Trading API base URL and require no authentication.
