      removal_date: '2026-07-31'
      replacement: https://apidocs.mediamath.com/apis/reporting-api
      statement: This API is deprecated and will be removed in July 2026.
      note: 'The provider announces this deprecation only as prose on the API documentation page. No operation
        in the contract carries deprecated: true and no Sunset or Deprecation response header is documented.
        This overlay surfaces the notice on the contract itself without mutating the original.'
