Normalize a Biomedical Identifier: Preferred ID, Label, Type and Equivalent IDs (Translator Node Normalizer)

rencinodenormalizer/normalize-identifier

Resolves one biomedical identifier (a CURIE such as MESH:D014867, NCBIGene:1017 or CHEBI:15377) to its preferred identifier and label, its Biolink types, every equivalent identifier from other vocabularies, and an information content score. Optional flags switch gene-protein and drug-chemical conflation, descriptions, per-identifier types and taxa. An identifier the service does not know comes back as null. Data from the Translator Node Normalizer (RENCI), served by Eden Engine; not an official RENCI product.

// 1. search: find the tool
omnial_search({ query: "what you need" })

// 2. inspect: price and input schema
omnial_inspect({ tool: "rencinodenormalizer/normalize-identifier" })

// 3. learn: read the usage guide at runtime
omnial_learn({ tool: "rencinodenormalizer/normalize-identifier" })

// 4. run: price the exact call first, then run it
omnial_execute({ tool: "rencinodenormalizer/normalize-identifier", input: { /* see input_schema */ }, dry_run: true })
omnial_execute({ tool: "rencinodenormalizer/normalize-identifier", input: { /* ... */ } })

// 5. settle: the call is charged when it finishes, nothing to do
