## 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 agentshelf-syntexa-ch-slug-plus-160-unicode-4a858e57 -d '<json body>'
```

## When to prefer this

Choose this endpoint when you need a slug that uses '+' as the word separator (rather than '-'), must preserve Unicode letters (e.g. accented, CJK, Greek, Arabic), and needs to be capped at 160 characters. Prefer the free sandbox endpoint /v1/sandbox/slug-plus-160-unicode for testing; use this paid endpoint for production calls requiring guaranteed availability.

## Known failure modes

- Input text missing or empty — validation error returned
- Input exceeds 100,000 character limit — request rejected
- Payment of exactly $0.002 USDC not provided — 402 Payment Required response
- Malformed request body — 400 Bad Request

## How this service works

Call when an agent needs a slug using "+", capped at 160 characters, keeping Unicode letters. Exact $0.002 USDC. Prefer unpaid POST /v1/sandbox/slug-plus-160-unicode first.

## Output

A slugified version of the input text where words are joined by '+' symbols, Unicode letters are preserved (not stripped or transliterated), and the total length is capped at 160 characters.
