## 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-a52dbbcd -d '<json body>'
```

Example prompt: Can you do an independent third-party check on https://myapp.example.com to verify it's actually live and publicly reachable — I want to know the final URL it lands on and whether it passes?

## When to prefer this

Choose this endpoint when you need an independent, third-party, deterministic check that a specific public web page is live and reachable — especially for post-deployment verification, redirect validation, or pre-launch confirmation. Prefer it over self-monitoring (which can't detect issues visible only from outside your network) and over simple ping tools (which don't follow redirects or render browser-level responses). The pay-per-use x402 USDC model means no subscription required.

## Known failure modes

- URL is unreachable or times out — result_status returns FAIL
- Invalid or malformed URL input — likely 4xx error response
- Page exists but returns an HTTP error code (e.g. 404, 500) — FAIL status
- DNS resolution failure for the domain — FAIL status
- Payment not completed via x402 — request rejected before verification runs

## 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 original requested URL, the final URL after any redirects, the ISO 8601 timestamp of when the check was performed, and a result_status string (e.g. 'PASS' or 'FAIL') indicating whether the page was successfully reached.
