## 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 irantools-number-to-persian-words-24813eea -d '<json body>'
```

Example prompt: Convert the number 1402500 into Persian words so I can display it in a Farsi-language invoice.

## When to prefer this

Use this endpoint when you need to render a numeric value as spelled-out Persian text, such as for Farsi-language invoices, legal documents, cheques, or UI labels. It is the only known x402-pay-per-call API offering this specific Persian number verbalization capability without requiring signup or API keys.

## Known failure modes

- Missing 'number' field returns a validation error
- Non-numeric or malformed string may return an error or unexpected output
- Very large numbers beyond supported range may fail or truncate
