# Welcome to Exchange APIs

Welcome to Coinbase Exchange API documentation for traders and developers! The APIs are separated into two categories, trading and market data:

* **Trading APIs** require authentication and let you place orders and access account information.
* **Market Data APIs** provide market data and are public.

Coinbase Exchange offers multiple connectivity options tailored to your trading and data needs:

* [REST API](/exchange/rest-api/requests) for lower-frequency trading and general requests.
* [FIX Order Entry API](/exchange/fix-api/order-entry-messages/order-entry-messages5) for higher-frequency trading.
* [WebSocket Feed](/exchange/websocket-feed/overview) for market data.
* [FIX Market Data API](/exchange/fix-api/market-data) for latency sensitive market data feeds.

Exchange's developer docs are part of [Coinbase Developer Platform](/), the single portal from which to access Coinbase's full suite of APIs and blockchain infrastructure products.

<Info>
  By accessing the Exchange Market Data API, you agree to be bound by the [Market Data Terms of Use](https://www.coinbase.com/legal/market_data).
