  - target: $.info
    update:
      x-apievangelist-profile: https://apis.io/provider/interpublic/
      x-apievangelist-surface-state: >-
        Frozen archive. Omnicom's acquisition moved the corporate site to
        omc.com; www.interpublic.com 301s there, while the apex host still
        serves this WordPress origin. Newest post 2025-11-24.
      x-apievangelist-auth-note: >-
        Reads are anonymous. Writes and privileged reads need a WordPress
        cookie plus X-WP-Nonce, which no third party can obtain. See
        authentication/interpublic-authentication.yml.
      x-apievangelist-error-envelope: >-
        {code, message, data:{status}} as application/json. Not RFC 9457.
  - target: $.servers
    update:
      - url: https://interpublic.com
        description: >-
          Production origin. Use the APEX host. The www host 301-redirects to
          https://www.omc.com/ and Link rel="next" pagination headers are
          rewritten to www, so a client that follows them naively leaves the
          API.
  - target: $.paths['/wp-json/wp/v2/posts'].get
    update:
      x-apievangelist-note: >-
        The newsroom collection. X-WP-Total observed at 346 on 2026-08-12;
        X-WP-TotalPages honors per_page. This is the highest-value operation
        on the surface.
  - target: $.paths['/wp-json/wp/v2/users'].get
    update:
      x-apievangelist-observed-status: 401
      x-apievangelist-note: >-
        Observed HTTP 401 rest_user_cannot_view anonymously. Author identity
        is only reachable indirectly through post.author.
  - target: $.paths['/wp-json/wp/v2/settings'].get
    update:
      x-apievangelist-observed-status: 401
      x-apievangelist-note: 'Observed HTTP 401 rest_forbidden anonymously.'
