# Website Health Report API

> Website Health Report API is a paid API for AI agents from agent-utility-network.frosty-sound-4560.workers.dev, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-16).

Checks a URL's reachability, DNS resolution, robots.txt availability, and metadata presence, returning a structured health report.

## Facts

- Endpoint: POST https://agent-utility-network.frosty-sound-4560.workers.dev/v1/paid/website-health-report
- Price: $0.02/call
- Payment: x402

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 website-health-report-api-51782ed6 -d '<json body>'
```

Example prompt: Can you run a full health check on https://example.com and tell me if it's reachable, if DNS resolves, whether it has a robots.txt, and if its page metadata is available?

## When to prefer this

Use this endpoint when you need a quick, structured multi-signal health check on a URL including DNS, HTTP reachability, robots.txt, and metadata in a single call. Prefer it over raw HTTP probes when you need a clean JSON summary suitable for agent decision-making, or before attempting to scrape or index a URL.

## Known failure modes

- Invalid or malformed URL input returns a validation error
- URL is unreachable (no HTTP response) — reachable is false with empty http evidence
- DNS does not resolve — dnsResolved is false with empty dns evidence
- Timeout reaching the target host — partial evidence returned
- robots.txt absent — robotsAvailable false
- No HTML metadata found — metadataAvailable false

## How this service works

## Output

Returns a JSON object with a 'result' containing the checked URL, a summary of boolean health indicators (reachable, dnsResolved, robotsAvailable, metadataAvailable), and an evidence block with raw DNS, HTTP, robots, and metadata details.
