## 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-changes-feed-asian-government-reference-data-33e87cf4
```

Example prompt: What Asian government reference data has changed since July 1, 2026? I want to know about any updates to policy rates, VAT, minimum wages, or public holidays across India, Japan, South Korea, Philippines, and Singapore.

## When to prefer this

Choose this endpoint when you need an incremental changelog of what has changed in Asian government reference data since a known checkpoint date — ideal for polling workflows, compliance monitoring, and automated alerts. Prefer it over the full snapshot endpoint when you only want to detect new or updated values rather than re-fetching all current values. Best suited for agents that run on a schedule and need to react only to changes.

## Known failure modes

- Invalid or future 'since' date returns empty changes array or 400 error
- Unsupported country code (non-Asian or outside covered set) returns no results
- Network timeout or service unavailability returns 5xx error
- Stale data flag set if official source has not been re-confirmed recently
- Payment failure (insufficient USDC balance) results in 402 error and no data returned

## How this service works

Authoritative Asian government reference values as clean JSON: central-bank policy rates, VAT rates, national minimum wages and public holidays for India (in), Japan (jp), South Korea (kr), Philippines (ph), Singapore (sg). 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 a 'changes' array. Each change entry specifies the data series (e.g. minimum-wage, policy-rate, VAT), the affected country code, and the effective date of the change. Entries are sourced from official primary sources (government gazettes, central-bank statements) and include staleness flags and last-confirmed dates.
