## 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 td-agent-utility-verify-page-browser-screenshot-http-check-28c29ddb -d '<json body>'
```

Example prompt: Can you verify that https://myapp.example.com is publicly reachable and the page actually loads correctly in a browser — I just deployed it and want to confirm it's live?

## When to prefer this

Choose this endpoint when you need an independent, external browser-level verification that a URL is publicly reachable — especially after deployment, publishing, or configuration changes. It is ideal when you need to confirm the final URL after redirects and want a deterministic PASS/FAIL result rather than a simple HTTP ping. Prefer this over raw HTTP HEAD checks when rendering and redirect resolution matter.

## Known failure modes

- URL is unreachable or times out — result_status returns FAIL
- Page requires authentication and returns 401/403 — may result in FAIL
- DNS resolution failure for the domain — FAIL with no final_url
- Redirect loop detected — FAIL
- Invalid or malformed URL provided — request rejected
- Payment not fulfilled via x402 — request not processed

## How this service works

Independent public URL, HTTP, DNS, TLS, browser screenshot and deployment verification for AI agents. Pay per completed job with x402 V2 USDC on Base.

## Output

A JSON object containing the result_status (PASS or FAIL), the requested_url, the final_url after any redirects, and the checked_at timestamp indicating when the check was performed.
