Кратко
The client has sent too many requests in a given time (rate limiting).
Когда возникает
Returned when a rate limit is exceeded; a Retry-After header may say how long to wait.
Частые причины
- Rate limit or quota exceeded
- Burst of requests without throttling
- Aggressive polling or bot traffic
Как устранить
- Respect the Retry-After header
- Add exponential backoff and throttling
- Cache responses to cut request volume
- Request a higher rate limit if needed
