summary: >-
  Upland ships dated release notes and one genuinely deprecated operation, and it executed a full
  blockchain migration with published cut-over block and timestamp. It publishes no versioning
  policy, no deprecation policy, no Sunset/Deprecation headers, no SLA and no status page.
versioning:
  scheme: path-prefix, applied to a single resource
  spec_version: 1.0.0
  docs_bundle_version: 1.0.6
  note: >-
    info.version in the live contract reads 1.0.0 while the copy embedded in the GitBook docs is
    named developers-api-v.1.0.6.json — the two disagree, and neither is dated. /v2/properties is
    the only versioned path. There is no version header, no version query parameter and no media
    type versioning.
  policy_published: false
deprecation:
  policy_published: false
  sunset_header: false
  deprecation_header: false
  deprecated_operations:
  - operationId: PropertiesController_getProperties
    method: GET
    path: /properties
    summary: List properties (Deprecated)
    replacement: GET /v2/properties (PropertiesController_getPropertiesWithNextPagePagination)
    sunset_date: null
    note: >-
      Flagged `deprecated: true` in the OpenAPI and labelled "(Deprecated)" in its summary. No sunset
      date, no removal notice and no Deprecation/Sunset response header. The replacement changes the
      pagination contract from currentPage/pageSize to nextPageToken, so it is a breaking migration
      for any consumer.

  withdrawn_capabilities:
  - what: Structure Ornaments, Outdoor Decors and Cars removed from escrow containers in production
    when: April 27 release note
    reason: The crates mechanism.

  node_software: Antelope Leap 5.0.3
  history_software: Hyperion 3.3.10
  note: >-
    A published, block-precise cut-over is a stronger lifecycle signal than most providers manage,
    and it is the only place Upland states an exact effective time for a breaking change.

status_page:

  probes:

    status: '<no response>'
    note: Host does not resolve.
  note: >-
    No status page, no uptime history and no incident feed was found on any Upland host. NO
    StatusPage pointer is wired in apis.yml. The nearest live health signal is third-party in
    nature — the Hyperion node's own /v2/health endpoint at https://chain-history.upland.me/v2/health,
    which returned 200 with service-level OK entries on 2026-09-02, and the ledger.upland.me block
    explorer.

application_lifecycle:
  states: [created, submitted, approved/active, inactivated, reactivated]
  note: >-
    Applications have their own lifecycle independent of the API. Inactivating and reactivating an
    application is the only credential-rotation path, and it issues a new access token, breaking
    live integrations. A Dev Shop registration is required before an application may run in
    production.
