Coinbase International Exchange enforces API rate limits at the individual API key level and at the account level.

API keys can be used simultaneously between trading and view-only sessions.

​
Summary

​
General Maximums

  • Maximum trading API Keys per account: 30
  • Maximum non-trading API Keys per account: 30
  • Maximum Drop Copy Sessions per account: 5
  • Maximum messages per second per account: 4000

​
API Limits

  • FIX Connections per API key: 1
  • FIX messages per second per API key: 800
  • REST requests per second per API Key: 40

​
FIX API Rate Limits

  • Connections per API key: 1
  • Messages per second per API key: 800 (session disconnects at 1000)

Your FIX session is disconnected if your messages exceed 1000 MPS.

Best Practice:

Spread messages across FIX sessions. If optimized at 800 msg/s per key with 5 keys, you can send 4000 msg/sec per account.

REST API Rate Limits

  • Requests per second per API Key: 40

​
REST Errors

HTTP Code: 429
Message: Rate limit exceeded - Server allows 100 requests per second
