## 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 text-utilities-slugify-keyword-extraction-93566c55 -d '<json body>'
```

Example prompt: Turn this article title into a URL-safe slug: 'Hello World: X402 Payments for AI Agents in 2025'.

## When to prefer this

Choose this endpoint when you need a deterministic, stateless text utility that is guaranteed not to retain data — ideal for privacy-sensitive content. It is well-suited for automated pipelines that generate URL slugs or extract keywords at scale, billed per call with no subscription overhead. Prefer it over general-purpose LLMs for slug/keyword tasks where reproducibility and low cost per call matter more than semantic sophistication.

## Known failure modes

- Text exceeds 20,000 character limit — request rejected with an error
- Empty or whitespace-only input — may return an empty slug or empty keyword list
- Non-text binary data submitted — unexpected output or error
- Payment not provided or invalid x402 payment — 402 Payment Required response
- Network timeout on very large inputs near the character limit

## How this service works

Small text utilities for agents and developers, paid per call: turn any text into a URL-safe slug, or extract the most frequent keywords (English and French stopwords removed). Up to 20,000 characters per call, deterministic, no data kept.

## Output

A JSON object containing the computed result: for slugify requests, a 'slug' field with the URL-safe lowercase hyphenated version of the input text; for keyword extraction, a list of the most frequent meaningful words after stopword removal in English and French.
