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. [Polymarket API endpoints: Gamma, CLOB and Data]() Match services and identifiers to the request.
