Classif.io

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.

Classif.io is listed with 1 API on the APIs.io network. Tagged areas include Apparel, Classification, Computer Vision, Fashion, and Image Recognition.

The Classif.io catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.

scored 2026-11-06 · rubric v0.27.0
Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.
The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Agent readiness — checks not met, largest first (exact, from this profile):
  • Machine-Readable Contract +18 pts — api_specs includes an OpenAPI document
  • MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
  • Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author
  • Machine-Readable Auth +10 pts — a served openid-configuration/oauth-authorization-server carrying `issuer` (served), else the securitySchemes class in the provider OpenAPIs — bound (mutualTLS, DPoP, Signature) > negotiable (oauth2 authorizationCode/clientCredentials, openIdConnect) > bearer (http bearer, apiKey)
  • Idempotency +9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
  • Stable Error Semantics +8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes

Each check links to what satisfies it. Publish the artifact, or tell us where it already lives, and the score moves on the next scoring run.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from the provider profile at artifacts.apis.io/classif-io/apis.yml: open an issue on github.com/api-evangelist/classif-io to ask a question or point us at an artifact you publish.

Markets this provider is in provisional

The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.

    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.

    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.'
