b.well

b.well Connected Health is a Baltimore-based digital health platform that unifies a person's fragmented medical, pharmacy, claims, wearable and lab data into a single FHIR-native longitudinal health record, then exposes that record to partner applications through a developer platform. The company operates a consumer-mediated health data network spanning millions of providers, health plans, HIEs/HINs, TEFCA QHINs and CMS-aligned networks, and licenses it to health systems, payers, employers and retail health brands who embed it in their own apps. Its developer surface is built around four Health SDKs (Web/TypeScript, Android/Kotlin, iOS/Swift and an AI SDK that speaks Model Context Protocol), a federated GraphQL gateway, REST endpoints for user data operations and webhooks, and a FHIR R4 server (the open-source Helix FHIR Server) supporting $everything and International Patient Summary retrieval. Authentication is OAuth 2.0 throughout — token exchange with OIDC for end-user context, client credentials for system-to-system access, and HMAC-SHA512 request signing on the user data operations API.

b.well publishes 2 APIs on the APIs.io network: Users API and Webhook API. Tagged areas include Company, Health, Healthcare, Digital Health, and FHIR.

The b.well catalog on APIs.io includes 1 event-driven AsyncAPI specification.

b.well’s developer surface includes documentation, API reference, getting-started guide, authentication, support, engineering blog, changelog, and 32 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.
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/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. This rating is computed from github.com/api-evangelist/b-well: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →
