The Polymarket API provides programmatic access to the world's largest prediction market. The platform is served by three separate APIs, each handling a different domain.

## Authentication
The Gamma API and Data API are fully public — no authentication required.
The CLOB API has both public endpoints (orderbook, prices) and authenticated endpoints (order management). See [Authentication](/api-reference/authentication) for details.
