knowledge-graph▌

Execute SPARQL against Wikidata's public Query Service and return structured JSON. Accepts raw SPARQL, a Wikidata entity QID (with optional property-PID filter), or a natural-language relational question that the agent translates into SPARQL. Honors output format (JSON/XML/CSV/TSV), label language, LIMIT, and the 60s endpoint timeout. Read-only — mutation queries rejected client-side.
