Rate limits

Limits are enforced per account, per minute, and every response tells you where you stand.

Headers

Every response carries X-RateLimit-Limit and X-RateLimit-Remaining. When you exceed the limit the API returns 429 rate_limited with a Retry-After header giving the number of seconds to wait. Back off until then — the window resets one minute after the first request that opened it, not on a fixed clock boundary.
