How this service works
Search the European Union's open data portal (data.europa.eu) by keyword, or fetch one dataset by id: title, publishing organization, last modified date where the portal gives one, number of files and the official link, under the portal's licence terms (a dataset's own licence is on its official page). Uncached: 404, not charged, fetched within about a minute.
Output
Returns a JSON object with ok status, the search query or dataset ID used, a list of up to 10 matching datasets (each with id, title, organization, last modified date, source URL, and resource/file count), total count of matching datasets across the portal, the data source attribution, country (European Union), licence details, and the timestamp when the data was fetched.
Example use cases
Researching EU climate datasets
“Can you search data.europa.eu for datasets about air quality monitoring? I want to know what's available, who published each one, and when they were last updated.”
Fetching a specific EU dataset by ID
“Look up the EU open data dataset with ID '100082-kanton-basel-stadt' and give me the title, the organization behind it, how many files it has, and the link to the official page.”
Discovering EU transport open data
“Search the European Union's open data portal for datasets related to railway infrastructure — show me what comes up, including the publishing body and last modified date for each.”
Technical details
Endpoint
GEThttps://api.maxwellinternational.ai/v1/gov/eu/open-data?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to discover or retrieve metadata for datasets published on the EU's official open data portal (data.europa.eu). Prefer it over generic web search when you need structured metadata (organization, file count, modification date, licence) rather than free-text results. Choose the Germany GovData or Poland dane.gov.pl siblings for those specific national portals instead.
Side effects
- 404 returned if dataset ID does not exist (not charged)
- No results returned if keyword matches nothing on the portal
- Stale or missing modification dates if the portal does not provide them
- Rate limiting or payment failure via x402 protocol
- Slow response (~1 minute) for uncached or first-time queries
