## 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-slug-generator-40-char-ascii-folded-2cca8d8d -d '<json body>'
```

Example prompt: Turn the title 'Héllo Wörld: An Introduction to Ünïcödé' into a tilde-slug, capped at 40 characters with ASCII folding.

## When to prefer this

Choose this endpoint when you specifically need tilde (~) as the word separator in slugs (rather than hyphens or underscores), require ASCII folding of Unicode/accented characters, and need the result capped at exactly 40 characters. It is a deterministic, no-LLM, no-network utility — ideal for reproducible identifier generation in pipelines. Use the free sandbox endpoint /v1/sandbox/slug-tilde-40-ascii first for testing before incurring the $0.005 USDC charge.

## Known failure modes

- Empty or missing text input returns a validation error
- Input exceeding maxLength of 100000 characters is rejected
- Payment of $0.005 USDC not provided or invalid triggers a 402 response
- 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-tilde-40-ascii first.

## Output

Returns a slug string derived from the input text, with non-ASCII characters folded to their ASCII equivalents, words joined by tilde (~) characters, and the entire result truncated to a maximum of 40 characters.
