## 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-keyword-extraction-a991df1f -d '<json body>'
```

Example prompt: Extract the top 5 keywords from this Persian article text: 'دولت ایران در نشست امروز درباره توسعه اقتصادی و برنامه‌های زیرساختی بحث کرد و تصمیماتی در زمینه بودجه گرفت.'

## When to prefer this

Choose this endpoint when you specifically need keyword extraction from Persian/Farsi text, particularly in an Iranian content pipeline. It is purpose-built for Persian NLP and handles RTL script, Persian morphology, and Farsi stop words correctly — unlike general-purpose English keyword extractors. Prefer it over generic NLP APIs when working with Persian-language documents, news articles, social media, or SEO content.

## Known failure modes

- Missing required 'text' field returns a validation error
- Non-Persian or empty text may return an empty keyword list or unexpected results
- Overly short texts may yield no meaningful keywords
- Invalid 'limit' value (non-numeric string) may cause unexpected behavior or be ignored
- Payment failure (insufficient USDC) results in HTTP 402 response
