## 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 delx-slug-validate-d33ffb72 -d '<json body>'
```

Example prompt: Can you validate the slug 'my-product-launch-2024' and make sure it's safe and under 50 characters?

## When to prefer this

Choose this endpoint when you need a fast, stateless, deterministic preflight check on a slug's format before storing, publishing, or routing it — particularly when you want machine-readable JSON output and a sub-cent cost per call. Prefer it over custom regex logic when you want a standardized, auditable validation result without side effects.

## Known failure modes

- Slug contains uppercase letters — returns non-conformant with pattern violation detail
- Slug contains underscores or special characters — flagged as invalid
- Slug exceeds max_len — returns length violation
- Empty slug input — returns validation error
- max_len set to zero or negative — may return error or undefined behavior

## How this service works

Validate a URL/product slug against a safe lowercase hyphen pattern — first-party local utility for agent preflight and proven micro-utils expansion. Returns deterministic machine-readable JSON for $0.001 USDC via x402 on Base. Execution is first-party, local-only, stateless, and memory-only with no paid upstream, no input retention, no web search, no live RPC, and no mediagen. Results are advisory; the caller owns authorization, budgets, and production controls. Sibling of Delx routes that alr…

## Output

Returns deterministic machine-readable JSON indicating whether the provided slug conforms to a safe lowercase hyphen pattern, including conformance status, any pattern violations detected, and whether the slug exceeds the optional max_len constraint.
