  note: 'CORRECTED 2026-09-05. This block previously read pricing "freemium" / label "Freemium" at confidence medium, derived
    from plans/classif-io-plans-pricing.yml — which was a fabricated scaffold carrying three invented tiers, retired the same
    day and now recording plan_count 0. The freemium label had no provider evidence behind it. The only real pricing evidence
    is archived marketing copy on the 2025-03-21 capture of the homepage: "Flexible Pricing Options: After the trial — Opt
    for a more cost-effective solution based on your volume, or enhance the model''s accuracy with advanced features for a
    fee." That establishes a trial and volume-based paid tiers and nothing more; no figure, currency or quota was ever published.'

description: 'Classif.io was a machine-learning classification service that offered to build a custom classification model
  from a written description of the customer''s task, publish it as a REST API, and let prospects try an interactive demo
  before buying. Its site listed sixteen such demo APIs — Fashion Style Classification, Custom Car Part Identification, Surgical
  Instrument Classification, Retail Planogram Compliance and others — each on its own landing page, alongside a "describe
  your use case" intake form. The homepage credited Kindwise, the team behind Plant.id, Insect.id, Mushroom ID and crop.health,
  as the maker. The service is retired: the classif.io domain is no longer registered, the last live capture of the site is
  2025-03-21, and no developer documentation, OpenAPI definition or other machine-readable contract survives in any public
  archive. See lifecycle/classif-io-lifecycle.yml for the retirement evidence.'

    type: Documentation
    removed: '2026-09-05'
    reason: Confirmed dead. classif.io does not resolve (NXDOMAIN from 8.8.8.8, 1.1.1.1 and 9.9.9.9) and the .io registry
      RDAP endpoint returns HTTP 404 for the domain object, so the registration has lapsed. Kept here as the historical record.
  description: 'One of the sixteen demo classification APIs Classif.io advertised, named "Fashion Style classification API"
    in the site navigation of the last archived capture of the homepage (2025-03-21). What the API actually accepted and returned
    cannot be stated: its landing page, https://www.classif.io/fashion-style-classification-api/, was real and linked from
    that navigation, but the Internet Archive holds no capture of it or of any other classif.io subpage, and the domain is
    no longer registered. No endpoint, schema, parameter or response of this API is asserted here, because none survives on
    any public surface. The API is retired along with the rest of the service — see lifecycle/classif-io-lifecycle.yml.'

    type: Website
    removed: '2026-09-05'
    reason: Confirmed dead and removed rather than left to rot, per the pointer-liveness rule. classif.io publishes no NS
      records and returns NXDOMAIN from 8.8.8.8, 1.1.1.1 and 9.9.9.9, and the .io registry operator's RDAP endpoint answers
      HTTP 404 "Object not found" for the domain object, so the registration has lapsed. This is not a bot challenge or an
      edge policy — there is no host to challenge us. A lapsed .io name is re-registrable by anyone, so leaving the pointer
      in place would eventually point readers at whoever picks the domain up next. The company's own site is recorded in lifecycle/classif-io-lifecycle.yml
      with its last archived capture instead.

x-coverage:
  state: none
  reason: defunct
  detail: 'Classif.io is gone, not merely unreachable: the .io registration has lapsed, the zone publishes no NS records,
    every resolver returns NXDOMAIN, and the registry operator''s RDAP endpoint answers HTTP 404 for the domain object, so
    the site, the Fashion Style Classification API page and every /.well-known/, /openapi.json and GraphQL probe fail at DNS
    before an HTTP request is made; the Internet Archive holds the homepage only — 18 rows, nothing after 2025-03-21, not
    one capture of any subpage — so no contract survives anywhere to harvest.'
