## 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 globalrules-country-currency-lookup-64871d72
```

Example prompt: What currency does Singapore use? Look it up from GlobalRules using the SG country code.

## When to prefer this

Choose this endpoint when you need a single, specific country fact — in this case currency — without pulling a full country dataset. It is ideal for lightweight agent workflows that need to enrich a transaction, form, or travel query with one verified data point per country. At $0.01 USDC per call it is cost-effective for occasional lookups. Prefer alternatives if you need bulk data across many countries simultaneously or if you need real-time exchange rates (this provides currency identity, not rates).

## Known failure modes

- Unsupported or invalid country code returns a 404 or error response
- Country code provided in wrong format (e.g. 3-letter instead of ISO alpha-2) may not resolve
- Payment failure (x402 protocol) if USDC balance is insufficient — returns 402 Payment Required
- Rate limiting or server unavailability on the Render-hosted service may cause timeouts
- Data may be outdated if the verified source has changed since last update

## How this service works

One specific fact for one country: VAT/GST rate, public holidays by country, visa requirements for travelers, tipping customs, power plug type, minimum wage, corporate tax, digital nomad visa, customs duty-free allowance and more. 162 countries, 56 fields, verified sources. Example: /api/v1/country/JP/vat

## Output

Returns a JSON object containing the country identifier, the currency field value (typically currency name and/or ISO code), and a last-updated timestamp indicating when the data was verified.
