How this service works
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.
Output
A list of up to 20 research datasets from Zenodo, each with its title, a plain-language licence verdict (public domain, attribution, share-alike, no-derivatives, non-commercial, or not stated), and metadata needed to locate and cite the dataset.
Example use cases
Commercial ML training data search
“Find me 10 research datasets about satellite imagery that I'm allowed to use commercially — show me the licence verdict for each so I know which ones I can actually train my model on.”
Academic citation-required data sourcing
“Search for open datasets on global CO2 emissions, show me any licence including ones that require attribution, and sort by best match — I just need to credit the source.”
Share-alike data policy check
“I need datasets on urban population density — can you find up to 15 of them and tell me which ones have share-alike or no-derivatives licences so I know which ones I have to be careful redistributing?”
Technical details
Endpoint
GEThttps://apexfaucet.xyz/api/x402/dataset-finder?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to discover open research datasets from Zenodo and require upfront licence clarity before use — especially when commercial use, redistribution, or derivative work constraints matter. Prefer this over generic web search when you need machine-readable licence verdicts rather than having to interpret licence text yourself.
Side effects
- Missing or too-short query string (q under 2 characters) returns validation error
- size parameter outside 1-20 range rejected
- No matching datasets found for highly niche query returns empty list
- Licence verdict may be 'not stated' if depositor did not provide structured licence metadata
- Payment failure (x402) if USDC balance insufficient
