# Polymarket APIs and data providers | Page 8

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.
