## 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 ausref-compare-oceania-government-reference-data-cross-country-94dd4ac6
```

Example prompt: Compare the corporate tax rate across Australia, New Zealand, Fiji, and Papua New Guinea — I need the current values with their official government sources and effective dates.

## When to prefer this

Use this endpoint when you need to compare a single government reference series (VAT, policy rate, minimum wage, CPI, corporate tax, etc.) across multiple Australasian/Pacific nations in a single call with official citations and dates. Prefer this over the per-country single-series endpoints when you need cross-country comparison rather than a single country's value, and over the full snapshot endpoint when you only need one specific series rather than all series for all countries.

## Known failure modes

- Invalid or unsupported series ID — returns error indicating valid series from /catalog
- Invalid ISO 3166-1 alpha-2 country code in the countries parameter
- More than 10 countries requested — returns validation error
- Country not covered by Ausref (non-Australasian country code) — returns not-found or empty result for that entry
- Payment not provided or insufficient — 402 Payment Required
- Stale data — last_confirmed date may lag if official government sources have not been recently scraped

## How this service works

Compare one government reference series (VAT, policy rate, minimum wage, CPI, corporate tax...) across up to 10 Australasian countries in one call, each row cited to its official source with effective and last-confirmed dates

## Output

A JSON array of rows, one per requested country, each containing the series value, country code, official source URL, effective date, and last-confirmed date for the requested reference series
