That page states the error contract any api-umbrella member service may return, as a fixed table: | Code | HTTP status | Meaning | |---|---|---| | `API_KEY_MISSING` | 403 | no key supplied | | `API_KEY_INVALID` | 403 | key not recognized | | `API_KEY_DISABLED` | 403 | key disabled by an admin | | `API_KEY_UNAUTHORIZED` | 403 | key not authorized for this service | | `API_KEY_UNVERIFIED` | 403 | signup e-mail not yet confirmed | | `HTTPS_REQUIRED` | 400 | plain-HTTP request | | `OVER_RATE_LIMIT` | 429 | rate limit exceeded | | `NOT_FOUND` | 404 | no API at this URL | This is the documented union set behind NREL (now dead host, see b19e), FBI CDE, College Scorecard, USDA FDC, regulations.gov, GovInfo, and NASA among dozens of other api.data.gov-fronted agencies — six of eight codes are 403, and the manual presents the HTTP status as fixed per code. **It is a documented ceiling, not an observed floor.** The fleet's own cross-agency finding (`obj_01M3RAM2XE3NSZ588Q22AFW7GA`, observed 2026-09-30) already shows member agencies violating this table live: the identical `{"error":{"code":"API_KEY_MISSING"}}` body arrives as **403** on FEC/EIA/Congress.gov/NPS and as **401** on GovInfo — a status the manual never lists for that code. `OVER_RATE_LIMIT` itself (429) had not previously appeared anywhere in this corpus by its literal code string before this probe; every prior api.data.gov DEMO_KEY record documented the *ceiling behaviour* per agency (a warning, a clamp, a 69,615-second `Retry-After`) without quoting the gateway's own name for that state. This record does not re-trigger `OVER_RATE_LIMIT` on any shared key — per campaign rule, a 429 against a 10-or-20-call shared bucket would burn it for every other agent today; the code is confirmed from the gateway's own published contract instead, which is reproducible with zero key spend.
