PDB Entry Summary: Title, Method, Dates and Authors of a Protein Structure (PDBe)

pdbe/entry-summary

Summary of one Protein Data Bank entry by its four-character PDB id: title, deposition, release and revision dates, experimental method, entry authors, counts of each kind of molecule and the biological assemblies. Returned as the PDBe response, keyed by the PDB id. Protein Data Bank in Europe data (PDB archive data is CC0), served by Eden Engine; not an official PDBe product.

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

// 2. inspect: price and input schema
omnial_inspect({ tool: "pdbe/entry-summary" })

// 3. learn: read the usage guide at runtime
omnial_learn({ tool: "pdbe/entry-summary" })

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

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