Rate limits

50 requests per minute per sub-account (and per agency for agency keys).

Key type	Limit	Counted per
Sub-account key	50 requests / minute	Sub-account (all its keys share the quota)
Agency key	50 requests / minute	Agency

The window is a fixed 60 seconds. Extra keys don’t add quota: two keys on the same sub-account share its 50 requests.

Over the limit

You get 429 with these headers:

Header	Meaning
Retry-After	Seconds to wait before the next request.
X-RateLimit-Limit	The limit (50).
X-RateLimit-Remaining	Requests left in the current window (0 on a 429).

{ "status": "error", "error": "Rate limit exceeded: max 50 requests per minute. Retry after 23s." }
