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.
Orderbook data, pricing, midpoints, spreads, and price history. Also handles order placement, cancellation, and other trading operations. Trading endpoints require [authentication](/api-reference/authentication).
A separate **Bridge API** (`https://bridge.polymarket.com`) handles deposits and withdrawals. Bridges are not handled by Polymarket, it is a proxy of fun.xyz service.
The CLOB API has both public endpoints (orderbook, prices) and authenticated endpoints (order management). See [Authentication](/api-reference/authentication) for details.
