What it does
The Wikidata Query Service answers SPARQL queries over Wikidata, the structured database behind Wikipedia with more than 100 million items: for example all cities with more than a million inhabitants, or all paintings by a given artist with their museums. Results are JSON, XML or CSV. Free, no key needed; data is CC0. Send a User-Agent and keep queries efficient.
