## 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 machine-commerce-lab-url-inspector-0785891d
```

Example prompt: Can you inspect the URL https://example.com and tell me what it returns?

## When to prefer this

Use this endpoint when an AI agent needs to fetch and inspect a public HTTP or HTTPS URL programmatically, especially in machine-payable x402 workflows where per-call micropayment is acceptable. It is well-suited for probing unknown endpoints, verifying web responses, or gathering information from a URL without setting up a full HTTP client.

## Known failure modes

- URL is not publicly accessible or returns a non-2xx status
- Invalid or malformed URL provided in the query parameter
- Target server is unreachable or times out
- URL resolves to a private/internal network address (blocked for security)
- Missing required 'url' query parameter returns a validation error

## How this service works

Machine-payable digital services for AI agents and autonomous software.

## Output

The agent receives details about the HTTP response from the inspected URL, including response metadata such as status codes, headers, and body content as returned by the target URL.
