## 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-info-5937c6a6
```

Example prompt: What are the ISO 4217 details for the Swiss franc — its currency code, numeric code, minor units, and which countries use it? Also, round the amount 1.005 to the correct number of decimal places for that currency.

## When to prefer this

Use this endpoint when you need authoritative ISO 4217 metadata — minor units, numeric codes, issuers, or country coverage — for a specific currency identified by code, number, or name. It is especially useful when you also need to correctly round a monetary amount to the currency's defined precision (e.g. for invoice generation, payment processing, or display formatting). Prefer it over generic country-to-currency lookups when the currency identifier is already known.

## Known failure modes

- Unknown currency code, number, or name returns a non-match result with reasons field populated
- Malformed or missing 'q' parameter returns a validation error
- Ambiguous name may return a partial or best-guess match with matchedOn field indicating how it was resolved
- Amount field with non-numeric value may return an error or be ignored
- Service degradation flagged in the 'degraded' boolean field

## How this service works

ISO 4217 currency details by code, number or name: minor units, issuers, countries; optional exact rounding of an amount.

## Output

Returns a currency object with the ISO 4217 code, name, numeric code, minor unit count, issuing authorities, and a list of countries (with alpha-2 codes) that use the currency. If an amount is provided, also returns a rounding object showing the input, the rounded value, the minor unit used, and the rounding method applied. Metadata includes source attribution, a summary verdict, and any degraded-data warnings.
