Buoy Health

Buoy Health is a Boston-based digital health company whose clinically-trained AI symptom checker and triage engine is offered to health systems, payers and employers as an embeddable API. The Buoy Symptom Checker API v2.0 exposes a conversational triage interview as REST resources — interviews, complaints, queries, intents, questions and results — so an integrator can create a de-identified anonymous interview from basic demographics, accept a chief complaint, walk an adaptively generated question sequence, and read back a differential diagnosis with a recommended level of care and customizable care-handoff destinations. The API is OAuth 2.0 protected against an Auth0-backed authorization server with separate sandbox and production environments, is documented on ReadMe with a published OpenAPI 3.0.1 definition and an llms.txt, and Buoy is HITRUST CSF certified.

Buoy Health publishes 6 APIs on the APIs.io network, including Complaints API, Intents API, Interviews API, and 3 more. Tagged areas include Symptom Checker, medical-triage, Digital Health, Healthcare, and Clinical AI.

Buoy Health’s developer surface includes documentation, API reference, support, engineering blog, authentication, sandbox, and 22 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/buoy-health: open an issue to ask a question, or submit a pull request to add artifacts.
