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 5 API contracts indexed on the APIs.io network, including Users API, Webhook API, and 3 more. Tagged areas include Company, Health, Healthcare, Digital Health, and FHIR.
The b.well catalog on APIs.io includes 1 event-driven AsyncAPI specification and 1 Spectral governance ruleset.
b.well’s developer surface includes engineering blog, documentation, API reference, getting-started guide, authentication, support, changelog, and 38 more developer resources.
Kin Score
Markets this provider is in provisional
The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.
| Market | Position | Depth | Registered MCP server | Declares compatibility |
|---|---|---|---|---|
| Certified Health IT (health IT accreditation and certification registers) | standard | 47.2 | - | - |
Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.
