Lifen

Lifen (Honestica SAS, Paris) is a French digital-health company whose Lifen Platform exposes FHIR R4 APIs that let e-health applications exchange health data with French hospital information systems and with healthcare professionals over the national MSSanté secure-messaging network. The platform is organised as API Services: Hospital API Services (an Identity & Encounter service giving secure access to patient administrative, coverage, encounter and appointment data inside a given hospital, and a Send-documents-to-EHR service that pushes medical documents into hospital Electronic Health Records), and National API Services (the MSS service for sending medical documents to healthcare professionals via MSSanté). Access is machine-to-machine over OAuth 2.0 client credentials, scoped by functional scopes and bound to a healthcare organisation through a database_reference. Lifen also ships an SSO/OIDC API and a signed webhook surface for patient and encounter events. The company is ISO 27001 certified and an HDS (Hebergeur de Donnees de Sante) certified health-data host.

Lifen publishes 7 API contracts indexed on the APIs.io network, including CommunicationRequest API, Coverage API, Encounter API, and 4 more. Tagged areas include Company, Healthcare, FHIR, Interoperability, and Health Data.

The Lifen catalog on APIs.io includes 1 event-driven AsyncAPI specification and 1 Spectral governance ruleset.

Lifen’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, signup flow, changelog, and 29 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
Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author
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)
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Registration Without a Human +6 pts — a `registration_endpoint` in the served RFC 8414 / OIDC discovery document
Documented Reversibility +6 pts — a reversal operation in the contract, graded up when a window is documented too

5 more unmet checks in the Agent Readiness table above.

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

Access Clarity scores 42.1 — up to +11.6 composite points
Contract Quality scores 55.3 — up to +11.2 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.

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
Medical Technology (certified health IT, FDA-authorized AI devices)	standard	18.8 (thin)	-	-

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 implemented 4

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.
