Available API Channels: REST vs WebSocket
CEX.IO provides two primary API channels tailored to different use cases:
🔹 REST API
Best for:
- Fetching historical data
- Checking account balances
- Placing individual orders
- Retrieving trade history
Use this when you need reliable, request-response interactions at regular intervals.
🔹 WebSocket (WS) API
Ideal for:
- Real-time market data streaming
- Live order book updates
- Instant notifications on order fills
- Continuous monitoring of open positions
WebSocket delivers data up to three times faster per request than REST, making it perfect for high-frequency and algorithmic trading setups.
