  Quantcast runs an Atlassian Statuspage and has executed one real API
  deprecation — the REST Reporting API was announced for sunset by
  1 October 2024 in favour of MetricsReport on the GraphQL API. There is no
  written deprecation POLICY (no notice period, no Sunset/Deprecation header
  support, no versioning policy page) and no changelog or release notes for
  either API. The developer portal itself carries a maintenance signal worth
  recording: every path outside /docs/* returns HTTP 500, and the whole site
  is served with meta robots noindex,nofollow and a "Copyright © 2024"
  footer.
versioning:
  scheme: uri-path
  current: v2
  path: /api/v2/graphql
  policy_url: null
  policy_note: >-
    No published versioning policy. v2 is the only version the portal
    documents; there is no v1 documentation and no statement of how long a
    version is supported.

  policy_url: null
  sunset_header: false
  deprecation_header: false

    Deprecation is communicated in documentation prose and page titles only.
    No RFC 8594 Sunset or Deprecation response header is documented.
