Semble
Semble is a London-headquartered (7 Bell Yard, London, WC2A 2JR) cloud clinical and practice-management platform for United Kingdom private and independent healthcare providers, from solo clinicians to corporate and enterprise clinics. Its modular EHR unifies patient records, appointment scheduling and online booking, video consultations, e-prescribing, pathology/lab ordering, clinical documentation, invoicing and payments (Semble Pay) and patient communications. Semble exposes a single open, secure public GraphQL API at https://open.semble.io/graphql, available to Semble clinics at no extra cost, letting developers read and write patients, bookings, availability, consultations, clinical pathways, prescriptions, labs, invoices, tasks, forms, questionnaires and webhooks. Authentication is API-key / token based (an x-token header carrying a role-scoped token that expires after 12 hours) rather than SMART-on-FHIR; the API is GraphQL-native and does not publish an HL7 FHIR CapabilityStatement or a downloadable OpenAPI. Semble emphasises GDPR compliance and UK healthcare security standards, with data encrypted in transit and at rest.
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.
API Evangelist profiles Semble the way a machine reads it — 11 machine-readable artifacts across 6 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 — Semble scores 49.4/100 (developing), with a separate agent-readiness read of 35/100 (agent aware). 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 Semble
Each block below is one kind of artifact we hold for Semble. 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 6
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.

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.

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.

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.
