## 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-australia-open-data-portal-search-8b460451
```

Example prompt: Can you search Australia's open data portal (data.gov.au) for datasets about renewable energy and show me the titles, publishing organizations, and links for the top results?

## When to prefer this

Choose this endpoint when you need to discover or retrieve metadata for datasets from Australia's official national open data portal (data.gov.au). It is the right choice when the user explicitly wants Australian government open data, as opposed to data from the US (catalog.data.gov), EU (data.europa.eu), Austria (data.gv.at), or Germany (GovData). Use it for keyword discovery across the portal or direct lookup of a known dataset ID.

## Known failure modes

- 404 not found (dataset ID does not exist) — not charged
- Dataset not cached, fetch may take up to ~1 minute
- Empty results if keyword matches no datasets on data.gov.au
- Payment required (402) if x402 payment header is missing or insufficient
- Rate limiting or network errors from the upstream portal

## How this service works

Search the national open data portal of Australia (data.gov.au) 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, a list of up to 10 dataset items (each with ID, title, last modified timestamp, source URL, publishing organization, and resource/file count), the original query, total result count across the portal, source metadata (data.gov.au, Australia), licence information (CC BY 4.0 for most datasets with per-dataset caveat), and the fetch timestamp.
