## 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-commerce-url-shape-validator-0d9d4a9d -d '<json body>'
```

Example prompt: Can you check if 'https://api.delx.ai/x' is a properly shaped URL — does it pass URL format validation?

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-use URL format check with no signup overhead, verifiable delivery on-chain, and a simple true/false validity result. Ideal for agents that occasionally need to sanitize or validate URL inputs without embedding a full URL-parsing library or setting up a subscription API account.

## Known failure modes

- Missing or empty `url` field in request body returns an error
- Malformed request body (non-JSON) may return a 400 error
- Payment failure via x402 protocol prevents call from completing
- Network timeouts if the Delx Commerce infrastructure is unavailable
