    The automated probe recorded hsts: null for this host; a direct HEAD of
    https://api.0xarchive.io/health on 2026-09-01 returned
    "strict-transport-security: max-age=31536000; includeSubDomains", so HSTS IS served. The
    probe's null is most likely because every path on this host except /health answers 401.
    Corrected here with the observation that established it.

  The automated probe covered the three hosts named in apis.yml apis[].baseURL and the OpenAPI
  servers[] block. The apex host 0xarchive.io was probed separately during this pass and is
  recorded below; it is the host that serves security.txt and the api-catalog.
