Rate Limit Headers

All responses include rate limit headers:

X-RateLimit-Limit: 100
X-RateLimit-Remaining: 95
X-RateLimit-Reset: 1640000000

Handling Rate Limits

When you exceed limits, you’ll receive a 429 response:

{
  "error": "Rate limit exceeded",
  "statusCode": 429
}

Best Practices:

• Implement exponential backoff
• Cache responses when possible
• Monitor rate limit headers
• Upgrade plan if needed
