Wikidata
Wikidata is a free, collaborative, multilingual knowledge graph hosted by the Wikimedia Foundation. It provides structured linked data for Wikipedia and other Wikimedia projects, as well as a public platform for anyone to read and edit. Wikidata exposes several APIs including a Wikibase REST API for entity read/write operations, the MediaWiki Action API for batch entity retrieval and editing, a SPARQL endpoint for complex graph queries, Linked Data URIs for individual entity access in multiple RDF formats, a real-time Server-Sent Events stream for change monitoring, and full database dumps for bulk data processing.
Wikidata publishes 5 APIs on the APIs.io network, including Descriptions API, Items API, Labels API, and 2 more. Tagged areas include Knowledge Graph, Linked Data, Open Data, Semantic Web, and SPARQL.
The Wikidata catalog on APIs.io includes 1 JSON-LD context and 2 Spectral governance rulesets.
Wikidata’s developer surface includes authentication, developer portal, documentation, support, engineering blog, and 19 more developer resources.
