## 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-separator-40-char-cap-unicode-letters-0bf9b772 -d '<json body>'
```

Example prompt: Turn 'Héllo Wörld – A New Adventure!' into an underscore-separated slug, keeping Unicode letters and capping it at 40 characters.

## When to prefer this

Choose this endpoint when you need underscore-delimited slugs (not hyphen-delimited), need Unicode letter preservation (non-ASCII scripts like Chinese, Arabic, accented Latin), and require a hard 40-character cap. Prefer the free sandbox variant (POST /v1/sandbox/slug-underscore-40-unicode) for testing before paying $0.006 USDC per call.

## Known failure modes

- Empty or whitespace-only input returns an error (minLength:1 enforced)
- Input exceeding 100,000 characters is rejected
- Payment of exactly $0.006 USDC required; missing or incorrect payment causes 402 response
- Network or server error returns 5xx with no slug output

## How this service works

Call when an agent needs a slug using "_", capped at 40 characters, keeping Unicode letters. Exact $0.006 USDC. Prefer unpaid POST /v1/sandbox/slug-underscore-40-unicode first.

## Output

A slugified string derived from the input text: word boundaries replaced with underscores, Unicode letters preserved, total length capped at 40 characters. Non-letter, non-underscore characters are typically stripped or normalized.
