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.
Example use cases
Rounding invoice amounts for KWD
“I'm generating an invoice in Kuwaiti dinars — can you look up KWD and round the amount 12.3456 to the correct number of minor units for that currency?”
Identifying currency for a numeric code
“I have the ISO 4217 numeric code 978 and need to know the currency name, which countries use it, and how many decimal places it has.”
Checking which countries use a currency
“Which countries officially use the currency with the code SEK, and what are its minor units and numeric ISO 4217 code?”
Technical details
Endpoint
GEThttps://country-codes-iso.x402tookit.com/currency-info?utm_source=zero.xyzWhen to prefer
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.
Side effects

- 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
