ClassPass

ClassPass is a fitness and wellness marketplace that lets consumers book classes, gym visits, and spa/wellness experiences across a network of studios in a single app using a monthly credit subscription. On the supply side, ClassPass runs a partner integration platform - centered on a named "ClassPass Inventory API" - that lets studios and their scheduling/booking software (100+ platforms, including Mindbody, Vagaro, Zen Planner, and Eversports Manager) push live class schedules, availability, and pricing to ClassPass and receive bookings and cancellations back. The partner developer portal at developers.classpass.com requires an approved partner login (Auth0) to view the API specification document and run certification tests; ClassPass does not publish a public, unauthenticated API reference, OpenAPI file, or Postman collection. ClassPass is now part of Playlist, the group formed together with Mindbody and Booker.

ClassPass is listed with 2 APIs on the APIs.io network. Tagged areas include Fitness, Wellness, Class Booking, Marketplace, and Studio.

ClassPass’ developer surface includes engineering blog and 8 more developer resources.

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/.

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.

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.

Market	Position	Depth	Registered MCP server	Declares compatibility
Wix App Market (third-party apps for Wix sites)	builds-on	34.5 (thin)	-	-

Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.
