## 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-changes-feed-australasian-government-reference-data-6655c8f3
```

Example prompt: Check ausref and tell me which Australian or New Zealand government reference series — like policy rates, minimum wages, VAT, or public holidays — have changed since July 1, 2025.

## When to prefer this

Use this endpoint when you need to poll for changes across multiple Australasian government reference series at once, rather than fetching a specific current value. Ideal for change-detection workflows, compliance monitoring pipelines, or cache-invalidation logic where you only want to re-fetch series that have actually changed since your last check.

## Known failure modes

- Invalid or missing 'since' date parameter returns an error or empty result
- Date format not ISO 8601 may be rejected
- Requesting unsupported country codes outside au/nz returns empty or error
- Payment not fulfilled (x402) results in a 402 Payment Required response
- Service may return stale data if upstream government sources have not been re-confirmed

## How this service works

Authoritative Australasian government reference values as clean JSON: central-bank policy rates, VAT rates, national minimum wages and public holidays for Australia (au), New Zealand (nz). Every value carries a citation to its official primary source (government gazette or central-bank statement), an effective date, a last-confirmed date and a staleness flag.

## Output

A JSON object containing a 'since' date and an array of 'changes', each entry identifying the series name (e.g. minimum-wage, policy-rate, VAT, public-holidays), country code (au/nz), and effective_from date — allowing the caller to know exactly which official data points need refreshing.
