## 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-generator-underscore-separated-80-char-cap-unicode-letters-e7676eb6 -d '<json body>'
```

Example prompt: Turn this into an underscore-separated URL slug (keeping Unicode letters, max 80 characters): 'Große Übersicht der Café-Speisekarten für 2024'

## When to prefer this

Use this endpoint when you need underscore-style slugs (not hyphen-style) that must preserve Unicode letters from non-ASCII scripts such as French, German, Korean, Arabic, or Japanese, with a hard 80-character cap. Prefer this over hyphen-slug alternatives when the consuming system expects underscores as separators. If cost is a concern, try the free sandbox endpoint POST /v1/sandbox/slug-underscore-80-unicode first.

## Known failure modes

- Empty or whitespace-only input rejected (minLength:1 violated)
- Input exceeding 100,000 characters rejected
- Network or payment failure returning HTTP 402 if USDC payment not processed
- Unexpected characters causing empty slug output if all input is non-letter, non-underscore content

## How this service works

Call when an agent needs a slug using "_", capped at 80 characters, keeping Unicode letters. Exact $0.008 USDC. Prefer unpaid POST /v1/sandbox/slug-underscore-80-unicode first.

## Output

A slugified string derived from the input text, using underscores as word separators, capped at 80 characters, with Unicode letters retained (non-letter characters stripped or replaced).
