## 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-text-normalizer-2a796985 -d '<json body>'
```

Example prompt: Can you normalize this Persian text for me so it has consistent characters and encoding: 'می‌خواهم به ايران بروم'?

## When to prefer this

Choose this endpoint when you need to standardize Persian/Farsi text that may contain mixed Arabic and Persian Unicode code points, inconsistent character encodings, or typography issues before NLP processing, search indexing, or database storage. It is especially useful for text scraped from Iranian websites where character inconsistencies are common. Prefer this over generic Unicode normalization (NFC/NFD) when the text is specifically Persian and requires Iranian typography conventions.

## Known failure modes

- Empty or missing 'text' field returns a 400 validation error
- Non-string input type causes schema validation failure
- Extremely long text strings may time out or be rejected
- Payment failure via x402 protocol returns 402 Payment Required before processing
