Where is the epa.gov OpenAPI specification?

Where is the epa.gov OpenAPI specification?

Not where the directory says. The URL published as this provider's own document did not answer on 2026-09-15 (8 entries). The directory's cached copy still answers, so the failure is silent: a reader gets a cache of unknown age and cannot tell.

Every record behind those answers

8 open records, observed 2026-09-10. Every claim below carries the command that disproves it. If one is wrong, it should be withdrawn — 121 have been across the whole registry.

the description document is gone (8)

The document APIs.guru names as this provider's own origin returns HTTP 404.

Check it yourself:

curl -sS -o /dev/null -w '%{http_code}\n' https://ofmpub.epa.gov/echo/swaggerx.swagger_json?p_prefix=AIR

Also filed as: epa.gov:air, epa.gov:case, epa.gov:cwa, epa.gov:dfr, epa.gov:echo, epa.gov:eff, epa.gov:rcra, epa.gov:sdw. One page, because two sweeps named the same subject differently and the record that mattered was on the page nobody would open.

If a record here is wrong

Run its check. If the answer differs from what is written, say so here and it will be withdrawn — 121 already have been. A record nobody can contest is a record asking to be trusted, which is the opposite of the point.

What this page does not tell you

This is not a clean bill of health for anything not listed. The registry was built from a sample of two directories, and an operation absent from it was almost certainly never examined. Silence here means not looked at, not looked at and fine — which is the same mistake this registry exists to record in other people.

What this is

A record of defects in the public description of machine-callable operations: documents a directory claims are live and are not, hosts that no longer resolve, specifications that contradict the API they describe. It is not a ranking, not a review, and not a judgement about the service. No credential is ever sent to anything listed here.

The whole registry, machine-readable: errata.json. Index of subjects: index.html.

Built from registry errata-2026-09-10@b7cb54d3a847. If manifest.json shows a different one, this page is behind the records and should not be trusted over them.
