Developer-first
Production API keys, release change feeds and source provenance—without operating your own terminology-import estate.
UK healthcare terminology, made operational
Reference data your software can trust.
Search, validate, map and track UK healthcare terminology with release-level provenance, secure workspaces and APIs built for product teams.
Versioned releases · Audit trail · Scoped API keys · Licence-aware access
Safe by design
Organisation-level access, payment entitlements, key revocation and immutable acceptance/audit records.
Human lookup
A focused browser interface for one-off code, mapping and history checks alongside the API.
Source roadmap
Built around the releases that matter.
dm+d, supplementary dm+d, SNOMED CT UK Clinical and Drug extensions, and historic UK cross-maps are held behind a licence review gate. We publish a source only when the applicable customer-use rights are confirmed.
