StuffThatWorks

StuffThatWorks is a community-driven health research platform where patients with chronic conditions share their real-world experiences to figure out, together, which treatments work best. Members complete structured surveys about their diagnoses, symptoms, and treatment outcomes, and the platform applies collective-intelligence and machine-learning models to turn thousands of patient reports into comparative, condition-by-condition treatment rankings across hundreds of chronic illnesses such as fibromyalgia, IBS, migraine, PCOS, and endometriosis. Founded in 2018 and headquartered in Tel Aviv, StuffThatWorks is backed by Bessemer Venture Partners. The consumer product is delivered as a web and mobile (PWA / Capacitor) application; probing the public domain surfaced no public developer API, SDK, OpenAPI, or developer portal at this time — only the SPA's private backend under /api/.

StuffThatWorks is profiled on the APIs.io network. Tagged areas include Company, Healthcare, Health, Patient Community, and Chronic Conditions.

StuffThatWorks’ developer surface includes engineering blog, support, and 4 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
Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author
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)
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)
Stable Error Semantics +8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0

11 more unmet checks in the Agent Readiness table above.

Kin Score — facets with the most composite points still available (weight × headroom):

Contract Quality scores 0.0 — up to +25.0 composite points
Access Clarity scores 0.0 — up to +20.0 composite points
Developer Ergonomics scores 2.4 — up to +19.5 composite points

Each check links to what satisfies it. Publish the artifact, or tell us where it already lives, and the score moves on the next scoring run.

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 the provider profile at artifacts.apis.io/stuffthatworks/apis.yml: open an issue on github.com/api-evangelist/stuffthatworks to ask a question or point us at an artifact you publish.
