## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability saylor-innovations-data-desk-european-open-data-search-f7f85b28
```

Example prompt: Search the European open data portal for datasets about air quality — I need the titles, publishers, countries, and download formats available.

## When to prefer this

Use this endpoint when you need to discover publicly available government and institutional datasets from European Union member states and EU institutions. It is ideal when the user wants to find raw open data sources on a topic (e.g. environment, transport, energy) rather than the data itself. Prefer this over general web search when you specifically need structured metadata about EU open datasets including publisher, country, file format, and official landing pages.

## Known failure modes

- Missing required 'q' query parameter returns a 400 error
- Query with no matches returns an empty datasets array with total_matches of 0 or null
- Overly broad or vague keywords may return hundreds of loosely related datasets
- The upstream data.europa.eu portal being unavailable causes a timeout or 502 error
- Non-English keywords may yield fewer results if the portal indexes primarily in English

## How this service works

Search the European open data portal (data.europa.eu) - dataset title, publisher, country, formats, keywords, modified date and landing page by topic

## Output

A JSON object containing the interpreted query string, the data source (data.europa.eu), an array of matching dataset objects (each with title, publisher, country, available formats, keywords, last modified date, and landing page URL), the number of results returned, and the total number of matches found in the portal.
