versioning:
  scheme: uri-path
  docs: https://api.6sense.com/docs/
  note: >-
    Each API carries its own major version in the path (/v1/, /v2/, /v3/) and
    advances independently. 6sense publishes a per-API "current stable version"
    table and keeps at least one prior version documented and callable for
    several of them, so older versions coexist with current ones rather than
    being removed on release.
  current:
  - api: Company Identification API
    version: v3
    path_prefix: /v3/company/details
    host: epsilon.6sense.com
  - api: Company Firmographics API
    version: v3
    previous_name: Lead Enrichment API
    documented_older_version: v2
    host: api.6sense.com
  - api: Lead Scoring API
    version: v2
    host: scribe.6sense.com
  - api: Lead Scoring and Firmographics API
    version: v2
    previous_name: Lead Enrichment and Scoring API
    host: scribe.6sense.com
  - api: People Enrichment API
    version: v2
    documented_older_version: v1
    host: api.6sense.com
  - api: People Search API
    version: v2
    documented_older_version: v1

    version: v2

deprecation:
  policy_url: https://api.6sense.com/docs/
  policy_published: true
  policy_text: >-
    "Each API will show the list of versions supported. You may receive timely
    notifications to upgrade the APIs to the latest stable version as we will
    deprecate the older versions which are no longer recommended to use."
  mechanism: email/CSM notification
  sunset_header: false
  deprecation_header: false
  notice_period: unpublished
  note: >-
    A deprecation policy exists and is stated in the API Portal, but it is a prose
    commitment rather than a machine-readable one. No RFC 8594 Sunset or
    Deprecation response header is documented, no notice window is quantified,
    and no dated end-of-life schedule is published for any version. An agent
    cannot detect an impending version retirement from the wire.

sla:
  url: null

  note: >-
    No public SLA or uptime commitment is published. 6sense sells on annual
    enterprise contracts and availability terms sit in the Main Services
    Agreement rather than on a public page.

release_notes:
  product:
    url: https://support.6sense.com/docs/product-release-notes

    cadence: monthly
    latest: '2026-07'
    note: >-
      Unusually, 6sense publishes a monthly changelog for the DATA rather than the
      code — accounts created, junk domains removed, fields refreshed, regional
      match-rate lift. For a data provider that is the release note that matters.
  api:
    url: https://docs.saleswhale.com/
    scope: AI Email API only
    latest: '2023-01-17'
    note: >-
      The only dated, per-change API changelog 6sense publishes covers the
      acquired Saleswhale surface and has not been updated since January 2023.
      The core data APIs have no changelog at all — version changes surface only
      as a new number in the portal's version table.
