  current:
    landmark-order-experience-api: 1.3.1
    landmark-conveyancing-experience-api: 0.8.1
    landmark-intelliworks-api: 2.3.0
    landmark-document-vault-api: 1.0.1
    landmark-milestone-notification-service-api: 1.0.0
  docs: https://www.landmarkcloudservices.com/
  note: >-
    The Milestone Service document states explicitly that the API uses semantic versioning. Version
    numbers appear only in the OpenAPI info block and the documentation - not in the path, not in a
    header, and not in a media type - so there is no addressable way for a consumer to pin a
    version at call time.
deprecation:
  policy_url: null
  policy_published: false
  sunset_header: false
  deprecation_header: false
  note: >-
    Landmark publishes no deprecation or sunset policy, and no RFC 8594 Sunset or Deprecation
    header support is documented. No operation in any of the five specs is marked deprecated. The
    closest published lifecycle signal is the reverse of deprecation: the Conveyancing Experience
    API marks not-yet-stable endpoints Preview and tells consumers not to build against them.
maturity_signals:
- api: Landmark Conveyancing Experience API
  stage: preview endpoints present
  detail: >-
    Add Document and Retrieve Document are marked Preview - published so consumers can see the
    direction of travel, explicitly not safe to build against. The Quotes and Cases schemas are
    described as settled.
  operations:
  - conveyances-experience-case-document-create
  - conveyances-experience-case-document-read
- api: Landmark Cloud Services documentation portal
  stage: unreleased APIs staged
  detail: >-
    Three further APIs - Intelliworks PMS, Property Risk v3 and Transaction Request Experience -
    are present but commented out in the portal navigation, and their documentation pages return
    404. They are staged for release rather than available.

status_page_note: >-
  No public status page. status.landmark.co.uk and status.landmarkcloudservices.com do not resolve,
  and neither the corporate site nor the documentation portal links to an incident or uptime page.
  Operational incidents are handled through the named support desks.
