Polymarket APIs and data providers
Choose an API by the information your application needs and how it must arrive. Official endpoints and third-party providers can serve different roles in market discovery, prices, order books, wallet research and historical analysis.
How to choose data apis
Start with the entity you need
Gamma is the starting point for market metadata, CLOB for an outcome-token book, and Data API for public wallet activity or rankings. A provider’s broad market coverage does not mean every route returns the same records or identifiers.
Compare the exact route
- Keep event IDs, Gamma market IDs, condition IDs and outcome-token IDs distinct when joining responses.
- Read the response envelope and pagination scheme: Gamma keyset responses use markets or events; Data v2 paged reads use data and pagination.
- Check dataset coverage, history, stream support, rate limits and output format for the endpoint you will actually call.
- Compare authentication and provider access terms separately from the choice of client library.
Public data reads and authenticated account actions need different handling. A route for reading a book is not permission to submit a signed order. Establish that boundary before selecting an SDK, stream or assistant connection.
