description: >-
  NTT DOCOMO, Inc. publishes no API versioning policy, no deprecation policy and
  no SLA, because it publishes no self-serve API. What it does publish are
  service-level lifecycle notices: a maintenance-window page for the d ACCOUNT
  Connect application site, a network-outage notice page for the mobile network,
  and dated end-of-service announcements for retired platforms. The lifecycle
  record of DOCOMO's developer programme is one of contraction — an API
  marketplace that opened in 2013 and closed in 2021, and an OpenID 2.0 login
  that ended in 2020.
versioning:
  scheme: none-published
  mechanism: null
  current: null
  docs: null
  notes: >-
    d ACCOUNT Connect exposes no version in its endpoint paths
    (/cgi8/oidc/authorize, /token, /userinfo) and its discovery document carries
    no version member. The JWKS path is the only versioned URL segment on the
    surface (.../ofrnt/v1.0/jwksget). The gated integration manual is the only
    place a version could be stated.
deprecation:
  policy_url: null
  sunset_header: false
  notes: >-
    No RFC 8594 Sunset/Deprecation header contract and no deprecation policy
    page is published. DOCOMO announces terminations as dated service-end
    notices rather than through a standing policy, so no `Deprecation` pointer
    is emitted.
sla:
  url: null
  uptime_target: null
  notes: >-
    No published uptime target or availability commitment for d ACCOUNT Connect
    or any other DOCOMO interface. Availability terms, if any, sit inside the
    partner agreement signed after review.

      Planned and ad-hoc maintenance windows for the d ACCOUNT Connect
      application site — the closest thing DOCOMO publishes to an API status
      page. Most recent posted window at fetch time: 2025-01-15 13:00–15:00 JST,
      full site stop.

      Mobile-network incident and outage notices for the carrier network as a
      whole. Network-level, not API-level; regional sub-pages return 403 to
      anonymous fetch.

      Carried DOCOMO and partner APIs (speech recognition, speech synthesis,
      chat dialogue, transit search, image recognition). The host no longer
      resolves — DNS NXDOMAIN as of 2026-07-25 — so even archived documentation
      is off the live web. Third-party SDK packages on npm still target it.

      "OpenID 認証 2.0方式を利用した「docomo ログイン」は、2020年9月をもって終了させて

  - name: FOMA / i-mode
    kind: Network and content platform
    closed: announced end-of-service; pages being progressively removed
    evidence: >-
      www.docomo.ne.jp's own 404 page states that pages are being retired in
      sequence because of the "FOMA" and "i-mode" service terminations. This is
      the mechanism by which DOCOMO's older technical documentation is
      disappearing.

    status: announced, not callable
    date: '2026-01-29'
    evidence: >-
      Partnership agreement with Aduna concluded 29 January 2026, announced
      30 January 2026; collaboration since June 2025. No endpoint, spec,
      sandbox or credential path published by DOCOMO, and DOCOMO was not listed
      on Aduna's operator wall as of 2026-07-25.
