This is not our API. This repository is an independent, third-party profile of a company's publicly available API surface, maintained by API Evangelist. API Evangelist does not operate, host, resell, or support this company's APIs, and is not affiliated with or endorsed by the company unless stated on the profile.
Where the information came from. Everything here is assembled from material a member of the public can reach with a browser and no credentials — the company's own website, developer portal and documentation, the specifications it publishes for public use (OpenAPI, AsyncAPI, JSON Schema,
apis.json,llms.txtand similar), its public repositories, and its public status, pricing and changelog pages. Nothing here is obtained by breaching a system, defeating an access control, or using credentials of any kind.The rating is an independent assessment. The Kin Score and Agent Readiness rating are independently calculated scores of a company's public API artifacts, produced by API Evangelist against a published rubric. They are not certifications, endorsements, security assessments, or audits, and they score published artifacts — not the quality, safety, or security of the software.
Corrections, re-scores, and removal are free. No partnership, contract, or purchase is required, and you do not need to justify the request.
- Something wrong? Open an issue on this repository, or email info@apievangelist.com.
- Published something new? Ask for a re-score and we will re-run the rating.
- Want the listing taken down? Say so and we will honor it. The profile is reduced to your company name, a factual description, and a link to your own site, and the company is recorded as unrated — never scored zero for having asked.
Response times. Acknowledgement within one business day; removal or restriction within two business days; corrections and re-scores within five business days.
On a security or compliance team? Email info@apievangelist.com with security in the subject line and you will get a person, not a form. We will tell you exactly which public URLs this profile was built from so your team can see the same surface we did, and we will take the listing down on request while you work through it.
Full detail: Where this data comes from
Semble is a London-headquartered cloud clinical and practice-management platform for United Kingdom private and independent healthcare providers. 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 — available to Semble clinics at no extra cost — for reading and writing patients, bookings, availability, consultations, clinical pathways, prescriptions, labs, invoices, tasks, forms, questionnaires, and webhooks.

- API style: GraphQL (single endpoint) —
https://open.semble.io/graphql - Authentication: API-key / token via the
x-tokenheader (role-scoped token, 12-hour lifetime); asignIn(email, password)mutation can also mint a token. Not SMART-on-FHIR. - Rate limit: 240 requests per minute (documented).
- FHIR / HL7: No FHIR CapabilityStatement,
/metadata, or/.well-known/smart-configurationis served — the API is GraphQL-native, not FHIR. - Downloadable spec: None published — the developer portal is a Docusaurus site rendering the GraphQL schema;
docs.semble.io/openapi.jsonreturns the SPA shell, and schema introspection is gated behind an authenticated token. - Availability: Documented and self-serve to Semble clinics (Settings → API Access), gated by Semble package and role.
The Semble public GraphQL API is modeled here by product domain (all sharing the single https://open.semble.io/graphql endpoint):
Patients, demographics, phone numbers, relationships, labels, memberships, access groups, allergy records, free-text records, patient documents, and patient communications.
