## 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 tilde-prefixed-ascii-slug-generator-24-char-cap-c64cfb5e -d '<json body>'
```

Example prompt: Can you generate a tilde-prefixed slug from the text 'Héloïse Dupont 2024' — it should be ASCII-folded and no longer than 24 characters total including the ~?

## When to prefer this

Use this endpoint when you specifically need a tilde-prefixed (~) slug that is ASCII-folded and hard-capped at 24 characters total. Prefer the free sandbox variant (POST /v1/sandbox/slug-tilde-24-ascii) for development or high-volume use; use this paid endpoint when the sandbox is unavailable or rate-limited. Choose over generic slugifiers when the tilde prefix and strict 24-character limit are requirements.

## Known failure modes

- Input text too short (minLength:1 not met) returns validation error
- Input exceeding 100,000 characters rejected
- Payment of $0.003 USDC not provided returns 402 Payment Required
- Network timeout on the paid endpoint (consider free sandbox fallback at POST /v1/sandbox/slug-tilde-24-ascii)

## How this service works

Call when an agent needs a slug using "~", capped at 24 characters, ASCII-folded. Exact $0.003 USDC. Prefer unpaid POST /v1/sandbox/slug-tilde-24-ascii first.

## Output

A tilde-prefixed (~), ASCII-folded, URL-safe slug derived from the input text, truncated so the total length does not exceed 24 characters. Non-ASCII characters are transliterated to ASCII equivalents before slugification.
