Happy Health

Happy Health, Inc. is an Austin, Texas digital health company behind the Happy Ring — an FDA-cleared, clinical-grade smart ring — and Happy Sleep, its at-home sleep-testing and sleep-apnea care service. The ring passively measures brain and body biomarkers using four LEDs, four electrodes, a three-axis accelerometer and two temperature sensors, capturing electrodermal activity, blood oxygen, pulse rate, heart-rate variability, respiratory rate, peripheral skin temperature and movement, and streams them over Bluetooth to the Happy Sleep app for clinician and researcher review. The company markets the platform to clinical-trial sponsors, provider groups and researchers with claims of cloud integration, an available SDK, eClinical/EDC and EHR integration, and SMART on FHIR interoperability — but publishes no public developer portal, API reference, SDK package or machine-readable specification, so none of that integration surface is reachable or evaluable without a sales conversation.

Happy Health is profiled on the APIs.io network. Tagged areas include Company, Health, Healthcare, Digital Health, and Wearables.

Happy Health’s developer surface includes support, pricing, signup flow, and 17 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 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 Ask about this →
MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship Ask about this →
Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author Ask about this →
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) Ask about this →
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) Ask about this →

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.

  detail: Happy Health's own technology page advertises "Cloud integration and SDK available" and SMART on FHIR data exchange,
    and the Happy Ring clinical microsite advertises eClinical/EDC and EHR integration, but there is no developer site to
    read — docs., developer. and portal. happysleep.com are wildcard catch-alls that 302 into the consumer checkout funnel,
    the api.happysleep.com origin returns 403 AccessDenied on every path, and the only route to the integration surface is
    a "Request a Demo" form.
