polymarket api

A high-performance REST and WebSocket interface for programmatic trading and real-time data retrieval on the world's largest decentralized prediction market.

The Polymarket API provides developers with direct access to the CLOB (Central Limit Order Book) built on Polygon. It supports automated market making, limit order management, and historical data scraping via the Gamma Markets protocol. Users leverage the API to execute trades with USDC, track volume across categories like Politics or Crypto, and monitor order book depth (L2 data) for thousands of active markets. By utilizing the Poly-SDK, engineers can integrate non-custodial wallet authentication and sign transactions for sub-second execution in high-liquidity prediction environments.
