What You Can Do

You can search Wikidata using four complementary methods: keyword search via the Action API for label-based lookups, semantic/hybrid search through the Vector Database for fuzzy concept matching, direct entity retrieval via Special:EntityData for instant JSON data, and SPARQL queries through WDQS for complex graph relationships and reporting. Each method is optimized for different use cases—from quick entity lookups to multi-table data analysis across millions of linked facts.

Features

Keyword search by label, alias, and description using Wikidata Action API (wbsearchentities)
Semantic and hybrid vector search via Wikidata Vector Database for fuzzy concept discovery
Direct entity JSON retrieval through Special:EntityData endpoint for real-time current data
SPARQL query support via Wikidata Query Service (WDQS) for complex graph relations and bulk reporting
Retrieve full entity metadata including claims, aliases, descriptions, and external identifiers
Pagination and filtering options (language, entity type, result limits) for refined results
Access both Q-entities (items) and P-entities (properties) in a single unified workflow
