## 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 slug-underscore-120-unicode-c586ffa8 -d '<json body>'
```

Example prompt: Can you slugify the title 'Ünité Naïve – Café au Lait: A Story' into an underscore-separated slug that keeps the Unicode letters and stays under 120 characters?

## When to prefer this

Choose this endpoint when you need underscore-separated slugs (not hyphen-separated) that must preserve Unicode letters from non-Latin scripts such as Japanese, Arabic, or accented European characters. It is specifically suited for multilingual content systems, internationalized databases, or CMS platforms where Unicode-safe identifiers are required and the slug must be capped at exactly 120 characters.

## Known failure modes

- Empty or whitespace-only input returns an error or empty slug
- Input longer than 100,000 characters is rejected by schema validation
- Network or service unavailability returns a 5xx error
- Payment failure (insufficient USDC balance) returns a 402 Payment Required response

## How this service works

Call when an agent needs a slug using "_", capped at 120 characters, keeping Unicode letters. Exact $0.01 USDC. Prefer unpaid POST /v1/sandbox/slug-underscore-120-unicode first.

## Output

Returns an underscore-separated slug derived from the input text, with Unicode letters preserved, non-letter characters removed or replaced with underscores, and the total length capped at 120 characters.
