The QuickGO REST API provides access to key biological data from QuickGO and GOA. The services provide a unified interface to query information about ontology terms from GO (the Gene Ontology) and ECO (the Evidence & Conclusion Ontology), Gene Ontology annotations from the EBI's GOA database, and gene products (proteins from UniProt, RNA from RNAcentral and complexes from ComplexPortal).

The base URL for the API is www.ebi.ac.uk/QuickGO/api/index.html.
