About Polymarket

Polymarket provides documentation for building on its prediction market platform, offering APIs and SDKs for developers. It covers market data access, trading operations, order placement and management, wallet authentication, and position management, with TypeScript and Python client libraries as well as direct API access (e.g. the Gamma API).

The documentation is organized around core concepts such as markets and events, positions and tokens, negative risk markets, prices and order books, and order lifecycle and resolution. It also documents market making tools including a matching engine, taker and maker rebate programs, liquidity rewards, a builder program, and a referral program, along with migration guides for moving between API/SDK versions.

This resource is intended for developers integrating with Polymarket to fetch market data, place and manage orders, or build trading and market-making tools. A separate documentation site exists for Polymarket US.
