umls_search — Search clinical terms/codes → UMLS concepts (CUIs). Maps free text or a source code to UMLS concept unique identifiers spanning SNOMED CT, ICD-10, RxNorm, LOINC, MeSH, etc. Example: umls_search({ query: "myocardial infarction", _apiKey: "your-key" })umls_concept — Concept detail for a CUI. Returns the preferred name, semantic types, atom count, and relation count for a UMLS Concept Unique Identifier. Example: umls_concept({ cui: "C0027051", _apiKey: "your-key" })umls_atoms — Source codes (ICD/SNOMED/RxNorm/LOINC) for a concept. Lists the source-asserted atoms of a CUI — the actual codes and names each vocabulary uses for that concept (the crosswalk table). Example: umls_atoms({ cui: "C0027051", _apiKey: "your-key" })umls_crosswalk — Crosswalk a code from one vocabulary to others. Given a code in a source vocabulary (e.g. an ICD-10-CM code), returns the concepts that share the same UMLS CUI in other vocabularies (SNOMED CT, RxNorm, LOINC, etc.). Example: umls_crosswalk({ source: "ICD10CM", code: "I21.9", _apiKey: "your-key" })Code samples (curl / TypeScript / one-click client install), schemas, and the live playground are on the pack page:
