Wikidata Vector Database (semantic search)

This is the highest-value feature of this skill. The Wikidata Vector Database at wd-vectordb.wmcloud.org provides semantic/hybrid search over all Wikidata items — something you can't do with the standard Action API or SPARQL.

A descriptive User-Agent header is required or you get 403.

curl -H 'User-Agent: WikidataSearchSkill/1.0 (contact: you@example.com)' \

Response includes QID, similarity_score, rrf_score, and source (vector vs keyword).
