Generated by API Evangelist on 2026-08-22 from the Happy Health public surface. Happy Health
does not publish an llms.txt of its own; this file is a faithful summary of what is publicly
reachable, not a document authored by the company.

## Status of the API surface

Happy Health publishes **no public developer portal, API reference, SDK package or
machine-readable specification**. The company markets an integration surface to clinical-trial
sponsors, provider groups and researchers, but every route to it is a demo or sales
conversation. Verified 2026-08-22:

- `https://www.happysleep.com/tech` — "Cloud integration and SDK available" and "Follows SMART
  on FHIR interoperability standards so users can transmit, share, and download their health
  data." No reference, no spec, no SDK link.
- `https://happyring.fiftyseven.co/clinical-trials.html` — "easy integration into eClinical
  Platforms and EHR"; the only call to action is "Request a Demo".
- `docs.happysleep.com`, `developer.happysleep.com`, `portal.happysleep.com` — these are **not**
  developer sites. `*.happysleep.com` is a wildcard catch-all: every unknown subdomain 302s to
  `https://happysleep.com/select-billing-method`, the consumer checkout funnel.
- `api.happysleep.com` — an S3/CloudFront origin returning 403 AccessDenied on every path.
- `app.happysleep.com` — a Vercel-hosted single-page app currently showing "A better Happy
  Health is coming soon"; it answers 200 with the same HTML shell for every path.
- No `/openapi.json`, `/openapi.yaml`, `/swagger.json`, `/api-docs`, `/graphql`, `/llms.txt`,
  `/.well-known/agent-card.json` or `/.well-known/agent.json` on any host.
- `github.com/happy-health` is the company's real GitHub organisation (20 public repositories),
  but every one of them is a fork of a third-party library — Kronos, SQLite.swift, flatbuffers,
  swift-protobuf, memfault-firmware-sdk, GCDWebServer — used in the iOS app and ring firmware.
  There is no first-party client library, no CLI and no published spec.
