SPARQL Query Runner
Pricing
from $0.35 / 1,000 bindings
Point at ANY public SPARQL endpoint (Wikidata, DBpedia, UniProt, government & museum Linked-Open-Data) and run a query over the W3C SPARQL 1.1 Protocol. SELECT flattens to dynamic columns per binding, ASK to a boolean, CONSTRUCT/DESCRIBE to triples. One actor, any knowledge graph. Pay per binding.
You can access the SPARQL Query Runner programmatically from your own applications by using the Apify API. You can also choose the language preference from below. To use the Apify API, you’ll need an Apify account and your API token, found in API & Integrations in Apify Console.
