summary: >-
  Green Check Access publishes a versioned contract (1.0.0) and nothing else about its lifecycle. No
  changelog, no release notes, no deprecation policy, no Sunset/Deprecation headers, no SLA, and no
  status page were found anywhere on the estate. No operation in the 49 is marked deprecated. A
  consumer has no published signal that the contract has changed.
versioning:
  scheme: none-in-path
  current_version: '1.0.0'
  source: OpenAPI info.version
  version_header: none
  version_in_path: false
  note: Paths carry no /v1/ segment; no Accept-version or API-Version header is documented.
deprecation:
  policy_published: false
  policy_url: null
  sunset_header: not-documented
  deprecation_header: not-documented
  rfc8594: false
  deprecated_operations: []
  deprecated_operation_count: 0
  note: >-
    Zero operations carry `deprecated: true` in the spec. That is a clean contract, not evidence of a
    policy — no policy document exists. NO `Deprecation` pointer is emitted.
status_page:
  published: false
  probes:
    - url: https://status.greencheckverified.com/
      status: 000
      note: Host does not resolve / no TLS endpoint. Redirected to the marketing 404 body.
    - url: https://greencheckverified.com/security/
      status: 404
  note: >-
    No status page, uptime page, or incident history was found on any host, and none is linked from the
    developer portal or the marketing site. NO `StatusPage` pointer is emitted.
changelog:
  published: false
  probes:
    - url: https://developer.greencheckverified.com/changelog
      status: 404
  note: >-
    The developer portal has Guides, Tutorials, Tools and API Reference sections and no changelog or
    release-notes section. llms.txt enumerates 13 documents; none is a changelog. NO `ChangeLog`
    pointer is emitted. This is the single most consequential lifecycle gap for an integrator: with no
    version segment in the path AND no changelog, a breaking change is undetectable until it breaks.
sla:
  published: false
  note: No SLA, uptime commitment, or support-response target is published on the developer portal or the marketing site.
support:
  channel: https://support.greencheckverified.com/
  type: knowledge base
  note: >-
    A Support Center (HTTP 200) carries operational knowledge articles, including per-POS connection
    guides that the OpenAPI schema descriptions link to directly (e.g.
    support.greencheckverified.com/en/knowledge/connect-greenbits-to-green-check).
