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.
API Evangelist profiles Lifen the way a machine reads it — 27 machine-readable artifacts across 2 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 56.4/100 (strong), with a separate agent-readiness read of 39/100 (agent ready). 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. Every facet and dimension name is a link: it opens that measurement's page on APIs.io, where the rating runs across the whole catalog — the exact checks that feed it, how every profiled provider distributes on it, and who is at the top of it.

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.

Postman Collections 7
A runnable collection turns the contract into something a developer can execute in seconds. We profile them because the fastest way to trust an API is to make a real call against it.
Ready-to-run Postman collections for exercising this provider's APIs.

Open Collections 8
Open, tool-agnostic collections carry the same runnable value as Postman without locking you to one client — the portable, forkable form of the same exercise.
Open, tool-agnostic API collections (OpenAPI-derived and Bruno).

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.

RATE LIMITSEvent 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.

ASYNCAPISecurity 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.
Authentication, domain security, vulnerability disclosure, and trust-center signals.
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.

This is an independent, third-party profile of Lifen, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
