## 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 country-and-currency-codes-iso-4217-currency-lookup-8545d571
```

Example prompt: What currency does Japan use, and what's its ISO 4217 code, numeric code, and number of minor units?

## When to prefer this

Use this endpoint when you need to resolve a country to its official ISO 4217 currency (code, numeric, minor units) or find all countries using a specific currency. Prefer this over a generic country-lookup endpoint when the primary output needed is currency metadata. Ideal for financial applications, e-commerce checkout, data enrichment pipelines, and internationalization workflows.

## Known failure modes

- Unrecognized country name or code returns an empty or error result
- Ambiguous query without mode specified may resolve incorrectly (use mode=country or mode=currency to disambiguate)
- Non-ISO currency names may not match
- Territories or special regions may not be included
- Rate limit or payment failure returns HTTP 402

## How this service works

Currency of a country (code, number, minor units) or every country using a currency, by ISO 4217.

## Output

Returns a currency object containing the ISO 4217 code, name, numeric code, and minor units, plus a list of countries using that currency (each with name, alpha-2 code, and a primary flag). Also includes source attribution, an 'asOf' timestamp, direction of the lookup, and optional disclaimer/summary fields.
