## 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-persian-digits-converter-7b052be0 -d '<json body>'
```

Example prompt: Convert all the digits in this text to Persian numerals: 'Invoice 1402/06/31, total: 12500 rials' — and make sure the direction is set to RTL.

## When to prefer this

Use this endpoint when you need to localize numeric content for Persian/Farsi-language applications, documents, or displays and require Unicode-correct ۰–۹ digit substitution. Prefer this over manual regex replacement when you also need RTL direction handling or when working within an Iranian-localization pipeline alongside other IranTools endpoints.

## Known failure modes

- Missing required 'text' field returns a validation error
- Very large text payloads may be rejected or time out
- Invalid 'direction' enum value may be ignored or cause an error
- Already-Persian digits in the input are passed through without double-conversion
- Network or payment (x402) failures return HTTP 402 or 5xx errors
