  • 100 requests per 10 seconds per token

Rate limiting is handled automatically, and requests will be queued if limits are reached.

Error Handling

The server provides detailed error messages for various scenarios:

  • Invalid input parameters
  • Rate limit exceeded
  • API authentication errors
  • Network issues
  • Invalid board/list/card IDs
