Polymarket APIs and Data Providers

Choose Polymarket data APIs for market discovery, outcome-token books, public wallet activity or historical datasets. Match the endpoint to the entity and delivery method.

How to choose data apis

Which identifiers and response format does your integration need?

Start with Gamma for market metadata, CLOB for an outcome book, and Data API for wallet activity or rankings.
Keep event IDs, Gamma market IDs, condition IDs and outcome-token IDs separate when joining responses.
Inspect each route’s envelope and pagination: Gamma keyset uses markets or events; Data v2 paged reads use data and pagination.
Separate public reads from authenticated account actions; check stream support, history coverage and limits for the exact endpoint.
