Kiute

Kiute was a French salon management and online booking platform for hair salons, barbershops and beauty institutes, formed from the September 2020 merger of Flexy (FlexyBeauty) and LeCiseau, backed by Serena, Newfund, Matmut Innovation, 123IM, UL Invest and Bourrelier Group. Its Kiute Pro product combined a point-of-sale till, appointment calendar, client records, marketing and an online booking marketplace serving roughly 10,000 beauty and wellness businesses. Booksy acquired Kiute on 2021-11-09 and has since retired the brand: as of 2026-08-17 every Kiute host answers a blanket HTTP 301 to Booksy for every path — kiute.com, www.kiute.com, app.kiute.com and kiute.fr to https://booksy.com/fr-fr/, pro.kiute.com to https://biz.booksy.com/fr-fr — and no api, docs, developers or help subdomain resolves. Kiute publishes no API, no specification and no developer program of its own; the successor surface is the Booksy Public API, profiled separately in this network at all/booksy/ and documented at docs.booksy.com.

Kiute is profiled on the APIs.io network. Tagged areas include Company, Marketplace, Beauty, Salon, and Booking.

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

13 more unmet checks in the Agent Readiness table above.

Kin Score — facets with the most composite points still available (weight × headroom):

Access Clarity scores 0.0 — up to +20.0 composite points

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/kiute/apis.yml: open an issue on github.com/api-evangelist/kiute to ask a question or point us at an artifact you publish.
