Rate Limiting: Understanding and Handling API Limits

How Rate Limits Work

Each API key has a requests-per-minute limit. When you exceed it, you receive a 429 status code.

Headers

• X-RateLimit-Limit — Your maximum requests per minute
• X-RateLimit-Remaining — Requests left in current window
• X-RateLimit-Reset — When the limit resets (Unix timestamp)

Handling 429s

Implement exponential backoff: wait 1 second, then 2, then 4, etc.
