## 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-certified-single-series-government-reference-data-australasia-70b475c9
```

Example prompt: What is the current GST rate for New Zealand? I need the official cited figure with the source URL and when it was last confirmed.

## When to prefer this

Use this endpoint when you need a single, specific government reference data point (one series, one country) for an Australasian or Pacific nation with an official source citation and freshness date attached. Prefer this over a country brief endpoint when you only need one data series to avoid paying for a full country package. Ideal for compliance workflows, financial models, or regulatory fact-checking where provenance and citation are required.

## Known failure modes

- Country not covered by ausref (service refuses with an error indicating unsupported country)
- Series not available for the requested country (partial coverage by country)
- Stale data flag set if value has not been recently confirmed from official source
- Payment failure if USDC/x402 payment not provided or insufficient
- Invalid country or series path parameter returns 4xx error
- Rate limit exceeded on free tier (50 calls/day)

## How this service works

Australasian government reference data for 8 countries as cited JSON: central-bank policy rates, VAT/GST and VAT registration thresholds, CPI, corporate, personal and withholding tax, social contributions, minimum wages, statutory interest, official FX rates, filing deadlines and public holidays (coverage varies by country). Every value carries its official source URL and last-confirmed date. Single facts $0.003; country brief (every series for one country) $0.01; cross-country compare (one series, up to 10 countries) $0.02; tax-ID and VAT-number checks $0.003; computed answers (VAT, income tax, working days, minimum-wage check) $0.01-$0.02. Pay per call in USDC on Base via x402 or MPP, no signup, or by card with credit packs or monthly plans on one key valid across all 7 regional services. Free tier: GET /catalog, plus a free email key with 50 answer calls a day, commercial use allowed. Finished answers, one cited dossier per call (supported countries vary per job; others are refused free): cost this hire (wage-floor verdict, contributions, employer cost) $0.50; charge this sale (which VAT applies, net/VAT/gross) $0.50; charge this sale certified (plus a signed VAT-rate extract) $0.75; invoice due date and statutory late interest $0.40; country evidence pack (brief plus signed extracts) $0.25; hire compare $0.75 for 2 countries, $1.00 for 3-5; next filings (VAT, PAYE, corporate-tax due dates rolled for holidays) $0.35.

Free trial: 3 computed-answer calls per day per IP on POST /v1/answers/* with header X-Free-Trial: 1 (without it, the normal x402 402; once used up, the 402 carries free_trial_resets_at). MCP answer tools use the trial automatically when no api_key is passed. Every series of the evaluation country is free. Card credit (same per-call price as x402): /pricing.

## Output

A JSON object containing the specific government reference value for the requested country and series, along with the official source URL, the last-confirmed date, and a stale indicator showing whether the data may be outdated. The response is structured as a single cited dossier for the given country/series combination.
