Hello Anton,

As requested, we added this endpoint to our WDQS allowlist. Please test a query and respond here with your sample query and its expected output if it is not working.

Thanks for your time,

Brian

A sample query worked:

SELECT ?triplesCount
WHERE {
  SERVICE <https://id.ndl.go.jp/auth/ndla/sparql> {
    SELECT (COUNT(*) AS ?triplesCount)
    WHERE {
      ?s ?p ?o .
    }
  }
}
