## 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-tilde-slug-generator-160-char-ascii-folded-777b3c5b -d '<json body>'
```

Example prompt: Turn this title into a tilde-separated ASCII slug capped at 160 characters: 'Héllo Wörld! My Amazing Blog Post About Crêpes & Café Culture'

## When to prefer this

Choose this endpoint when you specifically need a tilde (~) separator in your slug (as opposed to hyphens or underscores), require ASCII-folding of accented/non-ASCII characters, and need a 160-character cap enforced server-side. It is ideal for CMS systems or URL schemes that use tildes as delimiters. Use the free sandbox endpoint (POST /v1/sandbox/slug-tilde-160-ascii) first for testing before committing to the $0.001 USDC paid version.

## Known failure modes

- Empty or missing text input returns a validation error
- Text exceeding 100,000 characters is rejected by schema
- Payment failure (insufficient USDC balance) results in 402 response
- Network timeout if the service is temporarily unavailable
- Non-string input type causes schema validation error

## How this service works

Call when an agent needs a slug using "~", capped at 160 characters, ASCII-folded. Exact $0.001 USDC. Prefer unpaid POST /v1/sandbox/slug-tilde-160-ascii first.

## Output

A slugified string derived from the input text, with non-ASCII characters folded to their ASCII equivalents, words separated by tildes (~), and the result truncated to a maximum of 160 characters.
