## 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 asiaref-compare-multi-country-asian-government-reference-series-6b57ae7f
```

Example prompt: Compare VAT rates across Japan, South Korea, Singapore, Thailand, and Indonesia — I need each country's current rate cited to its official government source with effective dates.

## When to prefer this

Use this endpoint when you need to compare a single reference metric (VAT, corporate tax, policy rate, minimum wage, CPI) across multiple Asian countries in one call with official source citations. Prefer this over the single-country endpoint when doing cross-country analysis, market benchmarking, or building dashboards. It is distinctly suited for compliance research, investment analysis, and regulatory comparisons across Asia where provenance and official sourcing matter.

## Known failure modes

- Invalid series ID — series not in catalog returns an error; use GET /catalog to discover valid series identifiers
- Invalid country code — non-ISO or unsupported Asian country code returns a 400 error
- Too many countries — more than 10 comma-separated country codes will be rejected
- Country not covered — requested country may not have data for a given series, returning a null or absent row
- Stale data — last_confirmed date indicates data may not reflect very recent policy changes

## How this service works

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

## Output

A structured JSON array with one row per requested country, each containing the numeric or text value for the requested series, the official source URL, the date the value became effective, and the date it was last confirmed — enabling side-by-side comparison with full provenance.
