Wellhub

Wellhub (formerly Gympass) is a corporate wellbeing platform that gives employees access to a network of fitness, mindfulness, therapy, nutrition, and sleep partners through their employer's benefits program. For system integrators it publishes a public Integrations API: an OAuth2 client-credentials REST API that lets a client's HR or payroll system sync employee eligibility to Wellhub in real time, so employees gain access on hire and lose it on termination. The API models eligibility as batch jobs (create a job, add up to 500 items, submit, then poll status and read per-record errors) and is documented on a Stoplight-powered developer hub with a downloadable OpenAPI 3.0 contract and a synthetic-data Sandbox. Wellhub is backed by Atomico, HV Capital, and SoftBank Vision Fund.

Wellhub publishes 4 API contracts indexed on the APIs.io network, including Companies API, Employees API, Jobs API, and 1 more. Tagged areas include Company, Health, Wellbeing, Corporate Benefits, and Fitness.

Wellhub’s developer surface includes documentation, API reference, getting-started guide, authentication, sandbox, signup flow, engineering blog, and 20 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Health 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 applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% 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. This rating is computed from github.com/api-evangelist/wellhub: open an issue to ask a question, or submit a pull request to add artifacts.

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
Health and Wellness (consumer health, fitness, wearables)	undeclared	-	-	-

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.
