## 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 number-words-cheque-amount-in-words-ff01d7e4
```

Example prompt: Write out 2,450.75 US dollars in words for a cheque in English — use 'dollar' and 'cent' as the currency names, show cents as a fraction like 75/100, and use sentence case.

## When to prefer this

Choose this endpoint when you need to render a monetary amount as written words specifically formatted for cheque/check writing, with multilingual support (EN/ES/FR/DE) and options for fraction-style cents (56/100), custom currency names, plural forms, and letter casing — as opposed to general number-to-words conversion or currency rate lookup.

## Known failure modes

- Missing required 'amount' or 'majorName' parameters returns an error
- Amount exceeds 12 integer digits returns a validation error
- Invalid language code or enum value returns a bad request error
- Decimal places inconsistent with minorDigits setting may produce unexpected output
- Omitting minorName when amount has cents may produce incomplete output

## How this service works

Write a money amount in words for a cheque (EN/ES/FR/DE): you give the currency names, no rates; words or 56/100 cents.

## Output

A plain-text string of the monetary amount written out in the requested language and style, e.g. 'One thousand two hundred thirty-four and 56/100 dollars' or 'Mille deux cent trente-quatre euros et cinquante-six centimes', ready to be printed on a cheque.
