    API Evangelist enrichment pass. Every example below is a REAL response captured from
    data.americorps.gov on 2026-09-02; every header and status added is one that was
    observed on the wire or documented at dev.socrata.com. Nothing here is invented, and the
    underlying OpenAPI is not mutated.

        Read-only. Call this to learn a dataset's columns before querying /resource — or skip
        it entirely and read X-SODA2-Fields / X-SODA2-Types from a $limit=1 /resource call.
      x-richer-alternative: >-
        https://data.americorps.gov/data.json returns a DCAT-US 1.1 catalog with a fuller
        description of every dataset — issued/modified dates, keywords, bureauCode,
        programCode, accessLevel and a vcard contactPoint — none of which this endpoint
        returns.

            The same dataset.missing envelope is returned by the asset tier for an unknown
            four-by-four.

    update:

        GET /api/views, or https://data.americorps.gov/data.json. Do not hard-code — a
        four-by-four is reissued when a dataset is republished, and a retired one starts
        returning 404 dataset.missing with no in-band deprecation signal.
