NHS England

NHS England (which absorbed NHS Digital in 2023) is the national body that runs England's public health and social care API platform at digital.nhs.uk and api.service.nhs.uk. It publishes a large catalogue of internet-facing APIs - most of them HL7 FHIR R4 built to the FHIR UK Core profile - covering the national spine services: the Personal Demographics Service (PDS), GP Connect, the e-Referral Service (e-RS), the Electronic Prescription Service (EPS), the Organisation Data Service (ODS), Booking and Referral Standard (BaRS), immunisation history, the NHS App, NHS Notify, and the Directory of Healthcare Services. Access is governed centrally: applications onboard through the NHS API platform and authenticate with OAuth 2.0 bearer tokens - application-restricted (signed-JWT client credentials / API key) or user-restricted via NHS login (OIDC) and NHS CIS2 - with production access gated behind registration, assurance, and connection agreements. Home market is the United Kingdom (England). Positioning: a single national health system operating public, standards-based (FHIR UK Core) interoperability APIs rather than a commercial API vendor.

agent native

Real signal across most facets with visible, nameable gaps — the contract exists but is thin, or the portal is good while governance and commercial terms are absent.

Kin Score

API Evangelist profiles NHS England the way a machine reads it — 16 machine-readable artifacts across 10 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 — NHS England scores 45.2/100 (developing), with a separate agent-readiness read of 78/100 (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 NHS England

Each block below is one kind of artifact we hold for NHS England. 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 10

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.

National electronic database of NHS patient demographic details - name, address, date of birth, related people, registered GP, nominated pharmacy and NHS number - exposed as an ...

GP Connect Access Record - Structured - FHIR API

Lets authorised health and social care staff retrieve a patient's GP practice record as structured HL7 FHIR resources (medications, allergies, problems, immunisations, and more)...

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.

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 3

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.

Agentic Access 1

An x-agentic-access contract marks which operations are safe for an agent to run on its own and which need a human in the loop. It is the difference between an API an agent can use and one it can use safely.
