429
4xx Client ErrorToo Many Requests
The client sent too many requests in a given time, hitting a rate limit.
429 Too Many Requests means you've tripped a rate limit. The server should send a Retry-After header telling you how long to wait. The right response is to back off, ideally with exponential backoff and jitter, rather than hammering the endpoint - which only extends the block.
About 4xx Client Error

How to fix 429 Too Many Requests
- Honor the Retry-After header before retrying.
- Add exponential backoff with jitter to your retry logic.
- Cache responses or batch calls to cut request volume.
- If you legitimately need more, ask about a higher rate-limit tier.
