How this service works
Searches the official EU open data portal and returns datasets with what decides whether they are usable: the licence, classified by whether commercial reuse is allowed and what attribution or share-alike it demands. A dataset under a non-commercial licence is marked as unusable for a paid product rather than listd as if equivalent. Each result also carries its publisher, country, last modification date, the distribution formats available and how many there are, and direct links.
Output
A list of datasets from the EU open data portal, each with: title, licence type with commercial reuse classification, attribution and share-alike requirements, publisher name, country, last modification date, available distribution formats and their count, and direct links to the dataset and its distributions.
Example use cases
Vetting datasets for a paid product
“I'm building a commercial analytics dashboard. Search the EU open data portal for datasets about road traffic accidents across Europe and flag which ones allow commercial reuse — I don't want to get into licence trouble.”
Researching EU agriculture data
“Find me EU open datasets on agricultural land use or crop yields, and tell me who published them, when they were last updated, and what file formats are available for download.”
Checking licence compliance for a report
“I need to cite EU open data on urban population density in my client report. Search the EU data portal and tell me what attribution is required for each dataset and whether any of them have share-alike conditions I need to worry about.”
Technical details
Endpoint
POSThttps://research.halowerk.com/v1/dataset-discovery?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to discover datasets from the official EU open data portal specifically, and when licence usability (especially commercial reuse) is a critical factor in selecting data. Prefer this over generic web search when you need structured metadata including publisher, country, formats, and legally actionable licence classification rather than raw search snippets.
Side effects
- No datasets found for the query — returns empty results list
- EU open data portal is unavailable — upstream timeout or error
- Ambiguous query returns irrelevant datasets — agent should refine keywords
- Licence metadata missing for some datasets — fields may be null or unknown
- Rate limit or payment failure — x402 payment not processed
