description: >-
  What Empatica publishes about versioning, deprecation and operational status.
  There is no API-level versioning policy or deprecation policy document; what
  does exist is a dated product sunset notice for the E4 platform and an
  Atlassian Statuspage covering the live services.
versioning:
  api_policy_published: false
  scheme: uri-path (observed)
  current: v2
  detail: >-
    api.empatica.com serves under a /v2/ path prefix; /v1/ and /v3/ are not routed.
    No policy states how long a version is supported, how a new version is announced,
    or what constitutes a breaking change.

deprecation:
  policy_published: false
  notice_published: true
  headers:
    sunset_rfc8594: false
    deprecation_header: false
    detail: No Sunset or Deprecation response header was observed on any probed endpoint.

    detail: >-
      "As of February 14th, 2025, the E4 and its software suite have officially been
      sunset." The E4 developer surface went with it — developer.empatica.com now
      302s to the sunset notice, and the empatica/empatica.github.io repository that
      served it contains only index.html, 404.html and a CNAME. Every first-party E4
      SDK and the E4 Connect/Realtime documentation are gone.

  assessment: >-
    A dated sunset notice with a named migration target is real deprecation
    communication, and it is why a Deprecation pointer is emitted. It is NOT a
    deprecation policy: there is no stated notice period, no support window, and no
    machine-readable Sunset/Deprecation header on any endpoint.

      is the only machine-readable operational signal Empatica exposes.

  note: >-
    Component list is regionalised (EU/US) for the PKG Parkinson's surfaces and names
    third-party dependencies explicitly, which is unusually transparent. Several
    components share the generic label "Empatica Server", so a consumer cannot map an
    incident to a specific API surface.

    any Empatica surface.
changelog:
  api_changelog_published: false
  detail: >-
    No dated API changelog or release-notes feed exists. Product and regulatory
    announcements are published as blog posts at https://www.empatica.com/blog/, and
    operational history is available through the Statuspage incidents API, but neither
    is a versioned change record for a contract.
gaps:
- No API versioning policy and no deprecation policy.
- No RFC 8594 Sunset or Deprecation headers on any live endpoint.
- No SLA.
- No API changelog.
- Statuspage components are not mapped to API surfaces.
