Introduction
Overview of the Polymarket APIs
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.
APIs
**`https://gamma-api.polymarket.com`**Markets, events, tags, series, comments, sports, search, and public profiles. This is the primary API for discovering and browsing market data.
User positions, trades, activity, holder data, open interest, leaderboards, and builder analytics.
Orderbook data, pricing, midpoints, spreads, and price history. Also handles order placement, cancellation, and other trading operations. Trading endpoints require [authentication](/api-reference/authentication).
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 for details.
