## 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 open-data-catalog-search-aa7a757a -d '<json body>'
```

Example prompt: Search GovData for open datasets about air quality in Germany and show me the titles, publishers, and download links for up to 10 results.

## When to prefer this

Choose this endpoint when you need to discover and reference German or Bavarian government open datasets by keyword without needing to download the actual data files. Ideal for agents that need to surface metadata, publisher info, licenses, and download links from GovData or open.bydata catalogs. No API key required, making it easy to integrate. Not suitable if you need to fetch, parse, or analyze the actual dataset file contents.

## Known failure modes

- Query too short (under 2 characters) or too long (over 80 characters) returns validation error
- Invalid source enum value (not 'govdata' or 'openbydata') returns error
- No matching datasets found returns empty result set
- Upstream catalog API unavailable returns service error
- Query returns irrelevant results if search terms are too generic

## How this service works

Find public dataset catalog entries in GovData (Germany) or open.bydata (Bavaria): titles, short descriptions, publisher, source/identity links, source modification date, per-resource license references and access/download links. One catalog GET, up to 10 datasets; never downloads the actual source files. No API key needed.

## Output

Returns up to 10 catalog entries per call, each including: dataset title, short description, publisher name, source/identity URL, last modification date, per-resource license references, and access or download links. Does not download or return the actual dataset file contents.
