UniProt SPARQL Query: Proteins, Taxonomy and Citations (UniProt)

uniprot/sparql-query

Runs a SPARQL 1.1 SELECT or ASK query against UniProt's SPARQL endpoint (sparql.uniprot.org, the RDF triple store, not the UniProt REST API), covering protein entries, sequences, annotations, cross-references to other databases, taxonomy and citations, and returns the SPARQL-JSON result: the variable names in `head.vars` and one object per row in `results.bindings`. CONSTRUCT and DESCRIBE queries are not supported. Always include a LIMIT: broad or unbounded queries over the full dataset can run past the time allowed and fail, and a large result set makes a large response.

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

// 2. inspect: price and input schema
omnial_inspect({ tool: "uniprot/sparql-query" })

// 3. learn: read the usage guide at runtime
omnial_learn({ tool: "uniprot/sparql-query" })

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

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