Feature summary (what you would like to be able to do and where):

I would like to use the LDF API endpoint of WDQS in WBStack.

Use case(s) (list the steps that you performed to discover that problem, and describe the actual underlying problem which you want to solve. Do not describe only a solution):

I would expect /query/ldf to be available just like /query/sparql and like both are available in Wikidata.

Benefits (why should this be implemented?):

This would enable data access more performant than Sparql and compatible with Wikidata's existing https://query.wikidata.org/bigdata/ldf
