1.
Implement exponential backoff
When you receive a 429 error, wait before retrying with increasing delays.
2.
Cache responses when possible
Store frequently accessed data locally to reduce API calls.
3.
Use batch operations
Combine multiple operations into single requests where supported.
4.
Monitor your usage
Use the Primrose dashboard to track your API usage and set alerts.

Rate Limit Errors

What happens when you exceed limits

{
  "error": {
    "code": "rate_limit_exceeded",
    "message": "Too many requests",
    "retry_after": 60
  }
}

When rate limited, the response includes a retry_after value indicating how many seconds to wait before retrying.
