ChEMBL Target Search by Name or Keyword

chembl/target-search

Searches ChEMBL biological targets (proteins, protein complexes, cell lines, tissues, organisms) by name or keyword, for example kinase, EGFR or serotonin receptor. Returns a compact relevance-ordered page: target ChEMBL id, preferred name, organism, taxonomy id, target type and the species-group flag, up to 25 per page with offset paging.

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

// 2. inspect: price and input schema
omnial_inspect({ tool: "chembl/target-search" })

// 3. learn: read the usage guide at runtime
omnial_learn({ tool: "chembl/target-search" })

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

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