## 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 maxwell-x402-austria-open-data-portal-search-c7eb964e
```

Example prompt: Can you search the Austrian national open data portal for datasets about Klimaschutz (climate protection) and show me the titles, publishing organizations, and links?

## When to prefer this

Choose this endpoint when you need to discover or retrieve metadata for datasets hosted on the official Austrian national open data portal (data.gv.at). It is ideal for agents that need to find Austrian government data by topic or retrieve a known dataset's metadata by ID. Prefer this over generic web search when you need structured, authoritative metadata including publisher, modification date, and file count directly from the portal.

## Known failure modes

- Dataset ID not found returns 404 and is not charged
- Keyword returns zero results if no matching datasets exist on data.gv.at
- Portal unavailability may delay response up to ~1 minute (uncached fetch)
- Invalid or missing query parameters return an error
- Rate limiting or payment failure returns 402

## How this service works

Search the national open data portal of Austria (data.gv.at) 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 a list of matching datasets (up to 10 per call), each including: dataset ID, title, last modified timestamp, official data.gv.at URL, publishing organization name, and resource file count. Also returns the search query echo, total count of matching datasets, fetch timestamp, and portal licence details (CC BY 4.0 default with per-dataset licence on official page).
