eu. and us. draw on
one allowance rather than one each.
Response headers
Every response (including errors) includes your current budget:
Counts are shared across regions and reconciled continuously, so the
Remaining-* values are accurate within a moment rather than to the request.
Right after you move traffic to another region its headers can read high until
they catch up. A sudden increase in remaining budget is stale reporting, not
new headroom — if you pace against these headers, keep your own counter as a
floor.
HTTP 429: Too Many Requests
When any window is exhausted the server responds with429 (code
RATE_LIMITED) and adds a Retry-After header:
The
details field contains retry_after=<seconds>. The rejected request is
not counted against your budget.
