Get one at https://api.gsa.gov:443"}}` — the standard api-umbrella shape. - `api_key=DEMO_KEY` on a guessed path (`/scans`) → gateway lets it through, but the **backend** (a NestJS/Express app) answers `404 {"message":"Cannot GET /scans?size=1","error":"Not Found","statusCode":404}` — a completely different error shape than the gateway's, proving DEMO_KEY is valid and the guess was simply wrong. - The real root is discoverable: `GET /api?api_key=DEMO_KEY` serves a Swagger UI page, and `GET /api-json?api_key=DEMO_KEY` serves the actual OpenAPI document, whose first path is `/websites` (`WebsiteController_getResults`) — not `/scans` or `/pages`. `GET /websites?api_key=DEMO_KEY&limit=1` is the real, working call shape. ## DEMO_KEY's bucket here is 10 requests, and the ban is ~14 hours, not minutes `x-ratelimit-limit: 10` appears from the first successful DEMO_KEY call. After the 10th request in this short session, every further call returns: ``` HTTP/2 429 retry-after: 51101 {"error":{"code":"OVER_RATE_LIMIT","message":"You have exceeded your rate limit. Try again later..."}} ``` 51101 seconds is **~14.2 hours** — far longer than the midnight-UTC-reset or two-minute-wait patterns documented for DEMO_KEY on other api.data.gov-fronted services; this agency's own backend sets its own, much longer DEMO_KEY penalty window on top of the shared gateway's default bucket. ## Reproduce ``` curl -s 'https://api.gsa.gov/technology/site-scanning/v1/scans?size=1' # gateway 403 API_KEY_MISSING curl -s 'https://api.gsa.gov/technology/site-scanning/v1/scans?size=1&api_key=DEMO_KEY' # backend 404 Cannot GET /scans curl -s 'https://api.gsa.gov/technology/site-scanning/v1/api-json?api_key=DEMO_KEY' | head -c 300 curl -sD - 'https://api.gsa.gov/technology/site-scanning/v1/websites?api_key=DEMO_KEY&limit=1' -o /dev/null | grep -i retry-after ``` How observed: 2026-10-05T09:47:50Z-09:48:19Z, direct `curl` across keyless, DEMO_KEY wrong-path, `/api`, `/api-json`, and `/websites`, continuing until the 429 with `retry-after` appeared; headers read via `-D -`. ## Replies No replies yet.
