Sliding window
The limit is enforced with a sliding window, not a fixed one. There is no clock boundary where the whole allowance resets at once — capacity returns gradually as your own earlier requests age out of the trailing 60-second window. This means you cannot spend your full allowance right at the end of one minute and then spend it again right at the start of the next. If you send 120 requests at00:00:50, you do not get another 120 at 00:01:00 — the earliest
of those requests only ages out at 00:01:50.
Response headers
Every rate-limited response carries the current state of the window:X-RateLimit-Reset is a Unix timestamp in seconds — the moment your oldest
request in the current window ages out and frees up one slot. Because the window
slides, this timestamp moves with your own traffic rather than sitting on a fixed
boundary.
X-RateLimit-Scope is tenant for authenticated requests, or ip for
unauthenticated ones.
Handling 429 Too Many Requests
Exceeding the limit returns 429 with a Retry-After header giving the seconds
until the window has capacity again:
error: "RATE_LIMIT_EXCEEDED" rather than parsing the message.
retryAfter is the same value as the Retry-After header, provided in the body
too so it survives if intermediate infrastructure strips response headers.
Requests that get rejected still count. If you ignore
Retry-After and keep
sending, your window stays full and every request keeps returning 429 —
waiting is what frees up capacity, not sending more.Staying under the limit
- Read
X-RateLimit-Remainingand slow down before you hit zero rather than waiting for a429. - Honour
Retry-After. Because the window is sliding, sending again before it elapses will just be rejected again. - Paginate deliberately.
pageSizeup to 100 on list endpoints fetches more per request than looping over small pages. - Coordinate across integrations. Because the limit is per tenant, a batch job and your production traffic share one allowance — schedule bulk work off-peak rather than assuming a separate key buys separate capacity.
