Rate Limit Headers
Every API response includes rate limit information:
X-RateLimit-Limit: 60
X-RateLimit-Remaining: 45
X-RateLimit-Reset: 1691350320Handling Rate Limits
When you hit a rate limit, the API returns 429 Too Many Requests:
{
"error": "Rate limit exceeded",
"retry_after": 30
}Implementation tips:
- Check
X-RateLimit-Remainingbefore making requests - Implement exponential backoff on 429 responses
- Batch operations where possible
- Contact support for higher limits if needed
