Find open research datasets with a plain licence verdict per dataset
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.
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
