RCSB Protein Data Bank GraphQL API

The RCSB PDB GraphQL API provides flexible, field-selective access to the complete structural biology holdings of the Protein Data Bank. Callers can retrieve richly nested metadata about entries, polymer entities, non-polymer entities (ligands), branched entities, assemblies, interfaces, chemical components, PubMed literature records, and UniProt annotations in a single round trip. The schema mirrors the underlying PDBx/mmCIF data model and is served from a public endpoint requiring no authentication.
