Fasten Health is a healthcare data interoperability company offering a unified medical record platform that gives patients and developers access to clinical data across the U.S. healthcare system. Fasten began as an open-source project — Fasten OnPrem, a self-hosted personal/family electronic medical record manager that ingests FHIR Bundles and is distributed under GPL-3.0 with 2.7k+ GitHub stars. The team then productized the connectivity layer as Fasten Connect, a commercial REST + FHIR API and Stitch client SDK suite that lets developers retrieve clinical records from 50,000+ healthcare systems and 60,000+ organizations including Epic, Cerner, MyChart, Kaiser Permanente, HCA, Ascension, Humana, and Medicare. Founded by engineers who lived through the fragmentation of health data firsthand and based in New York City, Fasten ships GPL/MIT/Apache 2.0 open source repos alongside the hosted Fasten Connect platform.
Fasten Health publishes 11 API contracts indexed on the APIs.io network, including Bridge API, and 10 more. Tagged areas include Healthcare, FHIR, Personal Health Record, Electronic Medical Record, and Health Data Interoperability.
The Fasten Health catalog on APIs.io includes 1 event-driven AsyncAPI specification and 1 Spectral governance ruleset.
Fasten Health’s developer surface includes authentication, documentation, GitHub presence, engineering blog, changelog, signup flow, pricing, and 51 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/.

Agent readiness — checks not met, largest first (exact, from this profile):
MCP Server+12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship Ask about this →
Delegated User Identity+6 pts — a served discovery document listing authorization_code in grant_types_supported (served), else an oauth2 authorizationCode flow or openIdConnect declared in an OpenAPI (documented) Ask about this →
Protected Resource Metadata+5 pts — a served /.well-known/oauth-protected-resource carrying `resource` (documented), and naming its authorization_servers (verified) Ask about this →
4 more unmet checks in the Agent Readiness table above.
Kin Score — facets with the most composite points still available (weight × headroom):
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.
Not sure how this applies to your stack? Ask about any one item. Kin Lane reads every question, looks at your profile and your situation, and replies with what a fix would take — scoped to that one area, priced up front, yours whether you ship it or not. Ask a question →
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.
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.
Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.

condition-specific dashboards and diagnostic test tracking, with planned vaccination-recommendation, conversational medical-history,
and wearable-integration features. Distributed under GPL-3.0 with 2.7k+ stars; the official container image is hosted
at ghcr.io/fastenhealth/fasten-onprem. STATUS - the repository was ARCHIVED (read-only) on GitHub as verified on 2026-08-14;
last push 2026-02-13 and last tagged release v1.1.3 on 2024-10-01. The self-hosted product line is no longer under active
development; Fasten's active work is the commercial Fasten Connect platform.
