  openapi/phosphorus-api-openapi.yml -- plus negative searches for a status page, changelog,
  deprecation policy and SLA on phosphorus.io (page sitemap enumerated; status.phosphorus.io does
  not resolve)
versioning:
  style: uri-path
  current: v3
  also_live: v2
  detail: >-
    v2 and v3 are served concurrently from a single contract, split by capability rather than by
    generation. The contract's info.version is 2.0.0 even though it describes v3 paths, so the
    document version and the URI versions do not track each other.
deprecation:
  policy_published: false
  policy_url: null
  sunset_header: false
  deprecation_header: false
  deprecated_operations: 0
  detail: >-
    Zero of the 30 operations carry deprecated: true (every operation explicitly sets it to false),
    no Sunset or Deprecation response header is declared, and no deprecation policy page exists on
    phosphorus.io. No `Deprecation` pointer is emitted.
status_page:
  published: false
  url: null
  detail: >-
    status.phosphorus.io does not resolve in DNS and https://phosphorus.io/status/ returns 404. No
    third-party status page (Statuspage, Instatus, Better Stack) is linked from the site, the
    support page, or the footer. No `StatusPage` pointer is emitted.
sla:
  published: false
  detail: >-
    No SLA, uptime commitment or support-tier matrix is published publicly; terms of service at
    https://phosphorus.io/terms-of-service/ are website terms, not an API service agreement.
changelog:
  published: false
  detail: >-
    No dated API changelog or release-notes page exists on phosphorus.io. Product announcements are
    published as blog posts under https://phosphorus.io/resource-center/blog/ but are not versioned,
    not dated against API versions, and do not record breaking changes. No `ChangeLog` pointer is
    emitted.

  acquired_by: Dragos
  acquisition_date: '2026-06-01'
  announcement: https://phosphorus.io/phosphorus-joins-dragos-to-advance-device-to-network-xot-security/
  detail: >-
    Dragos acquired Phosphorus on 1 June 2026 to extend the Dragos Platform across the xOT
    environment. As of this probe phosphorus.io still operates as its own brand and the API is still
    served from *.phosphorus.io tenant hosts, but an acquisition is a lifecycle event for any
    integrator: base hosts, auth, and the support channel are all candidates to move to dragos.com.
