Complex Portal Search: Find Curated Protein Complexes by Gene or Name

complexportal/complex-search

Searches EMBL-EBI Complex Portal for curated macromolecular complexes by gene, protein or complex name and returns up to 20 per page: complex accession (CPX-...), name, organism, function text, predicted flag, and the first 20 interactors (identifier, name, type). `totalNumberOfResults` gives all matches.

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

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

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

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

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