How this service works
Look up an ISO 4217 currency. Pass code (alphabetic like USD, or 3-digit numeric like 840) for the canonical record, or country to find the currency/currencies a country uses. Returns the alphabetic + numeric code, English name, minor unit (decimal places — e.g. JPY 0, USD 2, BHD 3), and the countries using it. Bundled authoritative ISO 4217 data — the currency-code + decimal-places ground truth an LLM gets wrong on less-common currencies.
Output
Returns a JSON object with a `found` boolean, the query echo, data source info, and a `currencies` array containing each matching currency's alphabetic code, full name, numeric code, list of countries, and minor unit (decimal places).
Example use cases
Example prompt
“What are the full ISO 4217 details for USD — including its numeric code, minor unit, and which countries use it?”
Technical details
Endpoint
GEThttps://2s.io/api/iso/currencyWhen to prefer
Use this endpoint when you need authoritative ISO 4217 ground-truth data — official currency codes, numeric codes, minor units, and country associations — without managing API keys or subscriptions. Prefer it over scraped or LLM-hallucinated currency data when accuracy is critical for fintech, compliance, or EDI workflows.
Side effects
- Querying an unrecognized code or country name returns `found: false` with an empty currencies array
- Passing both `code` and `country` may produce unexpected precedence behavior
- Numeric codes must be passed as strings (e.g. '840' not 840)
- Payment failure (402) if USDC balance is insufficient or x402 header is missing
