        "note": "Format numbers for any locale using the platform's full ICU data. /v1/format?value=1234567.89&style=currency&currency=EUR&locale=de-DE returns the locale-correct string (e.g. 1.234.567,89 €). Styles: decimal, currency (ISO 4217, with currencyDisplay symbol/code/name), percent and unit (e.g. unit=kilometer-per-hour). Options: locale (BCP 47), minimum/maximumFractionDigits, useGrouping, notation (standard, scientific, engineering, compact — e.g. 1.2M), signDisplay. /v1/parts returns the formatToParts breakdown (integer, group, decimal, fraction, currency symbol, …) for building custom-styled displays. Everything is computed locally with no network calls. Ideal for internationalised UIs, invoices and receipts, dashboards, reports and anywhere numbers or money must read correctly per region. A locale number/currency formatter — distinct from foreign-exchange rates (currency), number-to-words (numberwords) and the base converter (baseconvert). No key, no cache.",
