Build, automate and scale your trading with FYERS APIs

FYERS APIs let traders and developers connect their trading systems directly with FYERS — access market data, place and manage orders, monitor positions, retrieve account information (orderbook, tradebook, positions, holdings and funds) and build automated trading workflows.

This flexibility makes FYERS APIs suitable for algo trading, custom trading setups, backtesting and automated execution. FYERS APIs are also AI-powered: FYERS MCP, FYERS AI Skills and FYERS GPT make it easier to understand the APIs, build workflows faster and unlock the full potential of API-based trading.

FYERS APIs are built with security in mind to prevent unauthorised transactions. All API requests and responses are served only over the HTTPS protocol. You can read more about when FYERS APIs were introduced here.
