Rate limits & paging

The limit is counted per organisation, per minute — not per key. Creating more keys does not buy more calls.

The headers

Three headers come back on every reply, not just the rejected ones, so you can slow down before you hit the ceiling:

X-RateLimit-Limit: 300
X-RateLimit-Remaining: 287
X-RateLimit-Reset: 41

X-RateLimit-Reset is seconds until the window resets. It is a fixed minute, not a sliding measurement.

Paging

Every list takes ?limit= and ?offset=. The maximum is 100 rows; the default is 25.

An unusable value — abc, -5 — falls back to the default rather than returning an error. Lists reply with a pagination object carrying the total.
