## 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-plus-40-ascii-fbeee6ea -d '<json body>'
```

Example prompt: Turn this title into a URL slug using plus signs, ASCII-folded and capped at 40 characters: 'Héllo Wörld! The Best Café Guide 2024'

## When to prefer this

Choose this endpoint when you need a '+'-delimited slug (rather than hyphen-delimited) with ASCII folding and a strict 40-character cap. Prefer the free sandbox endpoint /v1/sandbox/slug-plus-40-ascii first; use this paid endpoint only when the sandbox is unavailable or rate-limited. Prefer this over generic slug libraries when you need a hosted, stateless, per-call microservice with x402 payment flow.

## Known failure modes

- Empty or missing 'text' field returns a validation error
- Input text exceeding 100,000 characters is rejected
- Payment of exactly $0.005 USDC not provided results in HTTP 402 Payment Required
- Network timeout if the service is temporarily unavailable

## 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-plus-40-ascii first.

## Output

A slugified string derived from the input text, with non-ASCII characters folded to their ASCII equivalents, words joined by '+' characters, and the total length capped at 40 characters. For example, 'Héllo Wörld' becomes 'hello+world'.
