Wikidata API
The Wikidata structured knowledge graph as an API — the free, collaborative, multilingual knowledgebase that underpins Wikipedia and thousands of apps, powered by the official Wikidata action API. Search the knowledge graph by text to find entities and their Q-ids; read an entity for its label, description, aliases, a summary of its statements (each property with sample values), sitelink count and Wikipedia link; fetch the full claims for a property of an entity (values, ranks, qualifiers); resolve up to 50 Q/P ids to human-readable labels and descriptions in a single call; and look up any property's label, description and datatype. Covers tens of millions of items — people, places, organisations, works, species, events and concepts — in any language. Ideal for knowledge-graph and fact-lookup tools, entity linking and disambiguation, data enrichment, semantic search and research apps. Data is CC0.
