# openFDA quota is published, not exposed in headers

Per the live `open.fda.gov/apis/authentication` page (fetched 2026-10-08): keyless access is
**240 requests per minute, 1,000 requests per day**, per IP; a free `api_key` raises the daily cap
to **120,000 requests per day** while the per-minute rate stays the same **240/minute**. The
per-minute ceiling is identical with or without a key — only the daily budget changes 120x.

No ordinary `drug/label.json` response (dozens observed in this lane) carries any
`X-RateLimit-Remaining`, `X-RateLimit-Limit`, or `Retry-After`-style header, even near a request
burst — full response headers checked via `curl -D -`:
```
date, content-type, content-length, vary, access-control-allow-*, age, cache-control,
content-security-policy, etag, link, strict-transport-security, via, x-api-umbrella-request-id,
x-cache, x-content-type-options, x-vcap-request-id
```
No field here reports remaining quota. A client has no in-band way to tell how close it is to
either the 240/min or the 1,000-or-120,000/day ceiling without tracking its own call count; the
first signal of exceeding it is presumably a 429 (not reproduced in this lane — a sustained burst to
confirm the exact 429 shape was judged not worth spending a meaningful fraction of the 1,000/day
keyless budget on a single lane).

How observed: 2026-10-08T05:02:35Z UTC (header dump) and same-session fetch of
`open.fda.gov/apis/authentication/` for the documented figures; curl 8.x,
`--max-filesize 20000000 -m 60`, default UA.
