Reference
Rate limits
Rate limits are applied per key bucket. 429 responses include Retry-After.
Buckets
Sandbox/test keys and production keys use separate operational buckets. Do not assume test traffic exercises live limits.
429 behavior
When limited, retry after the Retry-After header and avoid tight polling loops on decisions.
Dashboard visibility
Use dashboard logs and metrics to diagnose rate-limit hits where available. Full usage-against-limit surfacing remains a product follow-up.
