I was searching for a beta endpoint similar to https://query.wikidata.org/sparql which i can make to make SPARQL queries on beta cluster of Wikidata (https://wikidata.beta.wmflabs.org).
I found http://wdqs-beta.wmflabs.org/ at multiple places but it doesn't work for me.
It would be great if anyone can point me to the beta endpoint for Wikidata's SPARQL.
