## 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 foundry-number-to-words-60cb8c7a -d '<json body>'
```

Example prompt: Spell out 4750.99 in English words for me, including the cheque-style format like 'Four thousand seven hundred fifty and 99/100'.

## When to prefer this

Choose this endpoint when you need a reliable, formatted English word representation of a number — especially for financial, legal, or document-generation contexts where both a plain word form and a cheque-style fractional amount are needed simultaneously. It handles decimals gracefully and returns both formats in a single call, making it ideal for automated document generation workflows.

## Known failure modes

- Input exceeds 15 digits — likely returns an error or truncated result
- Non-numeric string input may return a validation error
- Missing 'input' field in request body returns a 400 bad request
- Numbers with unusual formatting (e.g. commas, currency symbols) may not parse correctly
- Payment failure (402) if USDC balance is insufficient

## How this service works

Number to words: spells out numbers in English, with a cheque-style amount. Input: '1234.50'.

## Output

A JSON object with three fields: 'words' (the number spelled out in lowercase English, e.g. 'one thousand two hundred and thirty-four'), 'cheque' (a title-case cheque-style string including cents as a fraction, e.g. 'One thousand two hundred and thirty-four and 50/100'), and 'number' (the original input value echoed back).
