  checked: '2026-09-06'
  method: probed
  finding: The OpenAPI definitions held in this repository (openapi/_original/aoc-data-api.yaml and the five refined per-tag
    documents derived from it) were NOT harvested from the Architect of the Capitol. Every one declares servers[0].url https://api.aoc.gov/v1,
    and api.aoc.gov returns NXDOMAIN — no A record, no CNAME, no NS delegation — so the host has never existed. No /openapi.json,
    /swagger.json, /api-docs, GraphQL, MCP or AsyncAPI surface was found on any aoc.gov host either. These specs are unmarked
    scaffolds from an earlier bulk sweep and nothing in this enrichment pass was derived from them.
  evidence:
  - check: dig api.aoc.gov
    result: NXDOMAIN
  - url: https://api.aoc.gov/openapi.json
    status: 0
    note: connection failed, host does not resolve

    status: 404
  related: The only machine-readable surface bearing the AOC name is the "Architect of the Capitol" jurisdiction boundary
    layer on catalog.data.gov, which is served from maps2.dcgis.dc.gov and opendata.dc.gov and is published by DC GIS (District
    of Columbia OCTO), not by the Architect of the Capitol. It fails the ownership check and was deliberately not saved as
    an AOC contract.
x-coverage:
  state: none
  reason: no-developer-program
  detail: The Architect of the Capitol is a legislative-branch construction and preservation agency with no developer program
    at all — www.aoc.gov/developers and /api both return 404, there is no pricing, portal or reference page anywhere in its
    1,092-URL sitemap, and api.aoc.gov (the host named in the scaffolded OpenAPIs this repo holds) does not resolve in DNS.
