# Appendix C: Rate Limiting & Throttling

# Rate Limiting

## Rate Limit Tiers
- **Standard**: 1,000 requests/hour
- **Professional**: 5,000 requests/hour
- **Enterprise**: 50,000 requests/hour

## Rate Limit Headers
- `X-RateLimit-Limit`: Maximum requests
- `X-RateLimit-Remaining`: Remaining requests
- `X-RateLimit-Reset`: Reset timestamp

## Handling Rate Limits
- Implement exponential backoff
- Queue requests efficiently
- Cache results when possible
- Use pagination for large datasets
