Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 x402-agent-tools-web-status-checker-770ffb48
```

Example prompt: Can you check whether https://example.com is actually reachable and tell me what HTTP status it returns, how many redirects it goes through, and where it finally lands?

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call HTTP status probe with no API key setup — ideal for agents that need to spot-check URLs, audit redirect chains, or verify link liveness without a dedicated uptime monitoring subscription. It provides richer output than a simple ping (full redirect chain, TTFB, content type) and works on any public HTTP/HTTPS URL.

## Known failure modes

- Non-public or firewalled URLs may timeout or return connection errors
- Malformed or non-http(s) URLs will fail schema validation
- Very slow sites may hit a timeout threshold before responding
- Sites that block bots may return unexpected status codes (e.g. 403, 429)
- DNS resolution failures for invalid or offline domains

## How this service works

Pay-per-call tools for AI agents. USDC on Base or Solana via x402 v2; no keys, no accounts.

## Output

Returns a JSON object with: ok (boolean), final HTTP status code, full redirect chain (each hop with URL, status, and latency in ms), time-to-first-byte in ms, total round-trip time in ms, final resolved URL, number of redirects, and content-type header value.
