How to Choose a SDKs & APIs

  • •API coverage — confirm whether the SDK wraps the CLOB API (trading), Gamma API (market metadata), and Data API (portfolio/history), or only a subset of these endpoints.
  • •Official vs community — Polymarket's official TypeScript and Python SDKs are the most actively maintained; community libraries may lag behind platform API changes.
  • •Authentication requirements — check whether the API requires wallet signatures, API keys, or is publicly accessible without authentication, as this affects how you integrate.
  • •Language compatibility — ensure the SDK matches your stack. Official SDKs cover Python and TypeScript; other languages require direct REST or WebSocket integration.
  • •Documentation quality — prioritize SDKs with working code examples, active GitHub issue trackers, and recent commit history.

Frequently Asked Questions

Does Polymarket have a public API?

Yes. Polymarket provides the CLOB API for order book trading, the Gamma API for market and event metadata, and a Data API for portfolio and trade history. All are publicly documented and accessible to developers.

What is the best Polymarket Python SDK?

The official py-clob-client library is the most widely used Python SDK for Polymarket. It covers order placement, cancellation, and market data access via the CLOB API, with active maintenance from the Polymarket team.

How do I access Polymarket data programmatically?

Use the Gamma REST API for market metadata and event data, or the CLOB WebSocket feed for real-time order book updates. Several SDK wrappers listed above simplify authentication and response handling for both endpoints.
