  verification: Every path carries a 2026-09-12 anonymous HTTP 200. Query parameters are either JSON:API 1.0 members verified against the live surface (page[limit], page[offset], sort, filter, fields) or exposed-filter names the endpoint declares about itself in its own response `filters` member.
  caveat: 'robots.txt on www.ginniemae.gov carries "Disallow: /api/" for crawlers. The surface is not authenticated and not rate-limited in any advertised way, but it is also not an advertised developer product.'
