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.

Solid contracts, transparent operations, and an easy start — typically complete on four or five facets with one clear soft spot.

Kin Score

API Evangelist profiles Lifen the way a machine reads it — 13 machine-readable artifacts across 7 APIs, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.

Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Lifen scores 60.3/100 (strong), with a separate agent-readiness read of 67/100 (agent native). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.

Kin Score

This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

How we profile Lifen

Each block below is one kind of artifact we hold for Lifen. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.

APIs 7

Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.

Individual APIs this provider publishes, each with its own machine-readable definition.

Lifen CommunicationRequest API

The CommunicationRequest API from Lifen — 3 operation(s) for communicationrequest.

Lifen Coverage API

The Coverage API from Lifen — 1 operation(s) for coverage.

Lifen Encounter API

The Encounter API from Lifen — 2 operation(s) for encounter.

Lifen Organization API

The Organization API from Lifen — 1 operation(s) for organization.

Lifen Patient API

The Patient API from Lifen — 2 operation(s) for patient.

Lifen Practitioner API

The Practitioner API from Lifen — 1 operation(s) for practitioner.

Lifen Token API

The Token API from Lifen — 1 operation(s) for token.

MCP Servers 1

Model Context Protocol servers expose these APIs directly to AI agents. We profile them because agent-native access is the fastest-growing way this provider's capabilities actually get used.

Rate Limits 1

Rate limits are the difference between a demo that works and a production integration that doesn't fall over. Publishing them is an operational-transparency signal — and a hard requirement for any agent that plans its own throughput.

Documented rate limits and quota policies.

Event Specifications 1

Not every API is request/response. AsyncAPI describes the event-driven and streaming side — the webhooks and channels — so the asynchronous half of the interface is documented the same way the synchronous half is.

AsyncAPI definitions for this provider's event-driven and streaming APIs.

Security Posture 2

Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.

Scopes 1

OAuth scopes are the vocabulary of least-privilege access. Profiling them shows exactly what an integration — or an agent acting on a user's behalf — is allowed to do.
