# agent402.tools Site Status Snapshot

> agent402.tools Site Status Snapshot is a paid API for AI agents from agent402.tools, paid per call via x402, $0.008/call, status unknown (last checked 2026-09-14).

Runs a bundled 5-check health workflow on any public URL: DNS resolution, HTTP reachability, security headers, TLS certificate expiry, and robots.txt policy — all in one call.

## Facts

- Endpoint: POST https://agent402.tools/api/skill/status-snapshot
- Price: $0.008/call
- Payment: x402
- Status: unknown

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 agent402-tools-site-status-snapshot-65b7745f -d '<json body>'
```

Example prompt: Can you do a full health snapshot on https://mycompany.com right now — check if DNS resolves, the site is reachable, the TLS cert isn't expiring, security headers are set, and what the robots policy says?

## When to prefer this

Use this endpoint when you need a comprehensive, multi-dimensional health check of a single public URL in one call, rather than running separate tools for DNS, HTTP, TLS, headers, and robots.txt. Ideal for uptime monitoring workflows, pre-crawl validation, or security audits where you want a bundled snapshot with minimal latency overhead.

## Known failure modes

- Invalid or non-public URL returns a validation error
- DNS resolution failure is reported as part of the result rather than an API error
- Timeout on HTTP reachability check if the target server is very slow
- Malformed URL input (missing protocol or typo) causes request rejection
- TLS check may fail if the certificate is self-signed or uses an unusual CA

## How this service works

Bundled execution of the Site status snapshot workflow - The 'is this site healthy, addressable, and crawlable - right now?' workflow. DNS resolution → HTTP reachability → security headers → TLS certificate expiry → robots policy. Five tools, one structured status payload an operator (or an uptime bot, or a pre-flight check before an extract/crawl) can act on. One x402 payment runs 5 underlying tools (dns-lookup, http-check, http-headers, tls-cert, robots-check); partial-success per step.

## Output

A structured report covering five checks: DNS resolution result, HTTP reachability and status, security headers present/missing, TLS certificate expiry date and validity, and the site's robots.txt crawl policy — all returned in a single response.
