## 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-with-tilde-separator-unicode-safe-40-character-cap-551512c0 -d '<json body>'
```

Example prompt: Turn 'Héllo Wörld: My Amazing Blog Post Title' into a tilde-separated slug that keeps Unicode letters and stops at 40 characters.

## When to prefer this

Choose this endpoint when you need tilde ('~') as the word separator in your slugs (rather than hyphens or underscores), must preserve Unicode letters (e.g. accented or non-Latin characters), and need the result capped at exactly 40 characters. Prefer the free sandbox variant at POST /v1/sandbox/slug-tilde-40-unicode before using this paid endpoint.

## Known failure modes

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

## 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-tilde-40-unicode first.

## Output

Returns a slug string derived from the input text, with words joined by '~' instead of hyphens, Unicode letters preserved (non-letter characters stripped), and the total length capped at 40 characters.
