## 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 one-engine-text-normalize-slug-3f3a5988 -d '<json body>'
```

Example prompt: Can you slugify this title for me: 'The Best Café & Brunch Spots in São Paulo — 2024 Edition'? I need it formatted as a clean URL slug.

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call slug generation utility without spinning up your own text processing pipeline. It is ideal for autonomous agents that occasionally need to slugify strings as part of a larger workflow and want a reliable, serverless microservice billed per use via USDC on Base.

## Known failure modes

- Text exceeds 50000 character limit — request rejected
- Empty text input — may return empty slug or error
- Unexpected input types (non-string) — schema validation failure
- Payment failure via x402 — 402 response before processing

## How this service works

Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.

## Output

Returns a normalized, URL-safe slug derived from the input text, with special characters removed or transliterated, spaces converted to hyphens, and the result lowercased and sanitized for use in URLs or file paths.
