# 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.
