Frequently Asked Questions

No hard limits are set on our Wikidata SPARQL endpoint! Please note, however, that your queries may still fail due "Out of Memory" errors: remember to optimize your SPARQL, or use the Extract tool for large datasets.

You can use the online web interface (which is pretty close to the Wikidata Query Service you already love!) or direct query the SPARQL endpoint. In both cases, your queries are measured and billed by execution time.

Of course! From the online web interface you can save your result set and obtain a shareable link accessible by everyone, even if not authenticated in Semantic Builders. Click here for more informations.

You have a prepaid credit, which is consumed for each performed query (by the actual execution time, at millisecond granularity), for each saved query (every hour, at kilobyte granularity) and for each extraction task (fixed cost, plus the storage - billed as saved queries). You can opt to receive a mail notification when you credit drops below a certain threshold.

You are no longer able to perform queries, both on the web interface and the SPARQL endpoint, and to call the pay-per-call APIs.
