+# 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
+
+<CardGroup cols={1}>
+  <Card title="Gamma API" icon="database">
+    **`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.
+  </Card>
+
+  <Card title="Data API" icon="chart-line">
+    **`https://data-api.polymarket.com`**
+
+    User positions, trades, activity, holder data, open interest, leaderboards, and builder analytics.
+  </Card>
+
+  <Card title="CLOB API" icon="arrows-rotate">
+    **`https://clob.polymarket.com`**
+
+    Orderbook data, pricing, midpoints, spreads, and price history. Also handles order placement, cancellation, and other trading operations. Trading endpoints require [authentication](/api-reference/authentication).
+  </Card>
+</CardGroup>
+
+<Info>
+  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.
+</Info>
+

+
+## 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.
