## 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-40-character-ascii-folded-28c2391b -d '<json body>'
```

Example prompt: Can you turn 'Ärger mit Zürich – Café & Straße' into a clean underscore slug, no longer than 40 characters, with ASCII folding?

## When to prefer this

Choose this endpoint when you specifically need underscore-separated slugs (as opposed to hyphen-separated), with ASCII folding of Unicode/accented characters, and a strict 40-character cap. Prefer this over hyphen-slug variants when targeting Python identifiers, database column names, or file system keys that conventionally use underscores. Use the free sandbox endpoint (/v1/sandbox/slug-underscore-40-ascii) first to test before paying.

## Known failure modes

- Input text is empty (violates minLength:1 constraint)
- Input text exceeds 100,000 character limit
- Payment of $0.005 USDC not provided or invalid (x402 payment required)
- Network or upstream service error

## How this service works

Call when an agent needs a slug using "_", capped at 40 characters, ASCII-folded. Exact $0.005 USDC. Prefer unpaid POST /v1/sandbox/slug-underscore-40-ascii first.

## Output

Returns a slugified version of the input text: special and accented characters are ASCII-folded, words are joined with underscores, and the result is truncated to a maximum of 40 characters.
