  note: >-
    The only publicly stated API version anywhere on the Terminus / DemandScience
    surface is the Employee Automation API v4. No versioning policy, no version
    header, and no dated version train is published. The ABM Platform API reference
    is behind the developer.terminus.com login, so its versioning scheme is not
    publicly observable.
    UPDATED 2026-08-12: the Verify API (api.lastbounce.com), documented publicly in
    the help center, carries NO version segment in any of its paths
    (/api/singleEmail/validate, /api/batch/validation, /api/batch/{jobId}/status,
    /api/file/download/{jobId}) and no version header is documented — so it has no
    versioning scheme at all, which is a distinct finding from "undisclosed".
  per_api:
    Employee Automation API: {scheme: major-version-number, current: v4, since: '2022-07'}
    Verify API: {scheme: none, current: null, note: 'unversioned paths; no version header documented'}
    Terminus ABM Platform API: {scheme: unknown, current: null, note: 'reference behind the Redocly login'}
deprecation:
  policy_url: null
  sunset_header: unknown
  note: >-
    No general deprecation policy is published, but DemandScience does publish dated
    product retirement notices in the help center, with a stated removal date and
    required customer actions.

    Terminus merged into DemandScience. terminus.com 301-redirects to
    demandscience.com (every content path lands on a demandscience.com page with
    ?utm_campaign=terminus-redirect), app.terminusplatform.com redirects to
    app.demandscienceplatform.com, and support.terminus.com redirects to
    support.demandscience.com. Terminus-branded infrastructure remains in production:

    Signature Ads), terminus.bound360.com (Web Experiences), *.terminus.services.

  note: >-
    status.terminus.com resolves to terminus.statuspage.io and redirects to
    /inactive — the Statuspage account is no longer active. No replacement status
    page was found at status.demandscience.com (DNS does not resolve). No
    StatusPage pointer is wired in apis.yml because there is no working status page.

    the provider, whether the email address is B2C or B2B, and if the domain is

  detail: >-
    The first-party Terminus GitHub organization (73 public repos, "Terminus Account
    Based Marketing") still exists, but its published npm scope @terminus has not
    shipped a release since 2021-01-20 — four years before the DemandScience merger
    closed and five years before this probe. Nothing was carried forward under
    DemandScience branding. See packages/terminus-packages.yml.
