Api Endpoint

Open dataset finder + licence

Find open research datasets with a plain licence verdict per dataset: public domain, attribution, share-alike, no-derivatives, non-commercial. Find open datasets you are allowed to use. Pass ?q=electricity prices and get research datasets from Zenodo (700k+), each with a plain licence verdict read from the depositor's structured licence: public domain, attribution (credit needed), share-alike (derived data must carry the same licence), no-derivatives, non-commercial or not stated.
