What Is a Crypto Trading API?

A crypto trading API enables your bot to communicate directly with a cryptocurrency exchange.

You no longer have to manually open an exchange website, enter an order, and click Buy or Sell. Instead, market players increasingly use a trading bot to monitor prices and automatically buy or sell crypto when certain conditions are met.

Public API endpoints normally provide market information without account credentials. Private endpoints require authentication and allow the application to access account data or execute trades.

The best crypto trading APIs usually combine REST endpoints with WebSocket connections. REST handles individual requests, while WebSocket provides continuous market and order updates.
