To QLever

Rewrite a Wikidata Query Service query so it runs on QLever. Paste a query.wikidata.org link or the query itself.

The documentation on Meta-Wiki explains which parts of a query get rewritten, and the known limitations.

Advanced options
Used where a query asks for labels in [AUTO_LANGUAGE].

One-click bookmarklet

Drag this to your bookmarks bar. Then, while viewing a query on query.wikidata.org, click it to jump straight to QLever:

→ QLever

It just opens https://to-qlever.toolforge.org/to-qlever?url=… with the current editor URL — nothing is injected into the WDQS page.

API

GET https://to-qlever.toolforge.org/api/convert?url=<wdqs-url> → JSON { qleverUrl, query, warnings } (CORS enabled). Accepts url, query, or q, plus lang, map=0, subqueries=0 and languages=0. The /to-qlever endpoint 302-redirects; add preview=1 to see the converted query instead.
