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 automaton-alfa-url-health-check-374ef952
```

Example prompt: Can you do a full health check on https://api.mycompany.com — I want to know if it's up, how fast it responds, whether the SSL cert is valid and when it expires, and what security headers it's returning?

## When to prefer this

Choose this endpoint when you need a single, combined view of a URL's availability, latency, TLS certificate health, and security headers in one call. It is ideal for automated monitoring pipelines, pre-deployment audits, compliance checks, and incident triage where you need to quickly assess whether an endpoint is reachable and securely configured without running separate tools for each concern.

## Known failure modes

- Unreachable URL returns null status and null responseTimeMs with an error message describing the failure
- Invalid or malformed URL input may result in an error field being populated
- Sites with self-signed certificates will return tls.valid=false and an authorizationError string
- Network timeouts result in null response fields with an error description
- Non-HTTPS URLs return a null tls object since no certificate exists to inspect

## How this service works

Performs comprehensive URL health checks, measuring response time, status code, security headers, and TLS/SSL certificate validity. Route: GET /paid/health-check?url=https://example.com. Ideal for automated monitoring and endpoint auditing.

## Output

A JSON object containing the audited URL, the HTTP status code (or null on failure), response time in milliseconds, a TLS object with validity flag, issuer, subject, and valid-from/valid-to dates, a map of security headers present, and an error string if the request failed.
