## 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 cloudpulsepoint-site-health-check-combined-3971a18e -d '<json body>'
```

Example prompt: Before we start crawling https://example.com, run a full site health check — HTTP reachability, SSL certificate, DNS, and domain expiry — all in one shot and tell me if anything looks off.

## When to prefer this

Choose this endpoint when you need HTTP, SSL, DNS, and domain-expiry data together in a single round-trip — it is cheaper and faster than calling four separate check endpoints. Ideal as a pre-flight gate before crawling, deploying to, or establishing a dependency on any public website.

## Known failure modes

- HTTP 400 if the URL resolves to a private, loopback, link-local, or cloud-metadata address (SSRF protection)
- HTTP 400 for malformed or unparseable URL input
- Timeout if the target site is extremely slow to respond
- Partial results if one check (e.g. WHOIS) times out independently
- Payment failure if USDC balance is insufficient for the $0.05 charge

## How this service works

Run HTTP + SSL + DNS + domain-expiry in one call and return a combined health snapshot. The single pre-flight check to run before crawling, deploying to, or depending on a site — cheaper and one round-trip instead of four.

## Output

A combined JSON health snapshot covering: HTTP reachability status code and response time, SSL certificate validity and days until expiry, DNS resolution result for the host, and domain registration expiry date with days remaining — all returned in a single response.
