  description: Wikidata provides multiple APIs for accessing its structured knowledge graph. The Wikibase REST API (OpenAPI-based) provides entity read/write operations. The MediaWiki Action API provides entity retrieval, editing, and search via the wbgetentities, wbsearchentities, and wbeditentity actions. The SPARQL endpoint at query.wikidata.org supports SPARQL 1.1 queries.
