## How to call it through Zero

```sh
zero fetch --capability mat-web-data-toolkit-website-audit-6beebdbd
```

Example prompt: Can you audit https://example.com for me — I want to see its TLS certificate status, any missing security headers, SEO metadata like the page title and description, and how fast it responds?

## When to prefer this

Choose this endpoint when you need a comprehensive, structured JSON audit of a single public webpage covering TLS, HTTP security posture, SEO signals, redirect behavior, and server metadata all in one call — especially for pre-launch checks, competitive research, or monitoring a specific URL's health indicators.

## Known failure modes

- Invalid or malformed URL returns an error response
- Private or localhost URLs may be blocked or return no data
- Sites that require authentication will return a 401/403 with limited metadata
- Very slow or timing-out origins may cause incomplete responses
- URLs with non-HTML content types may yield sparse SEO fields

## How this service works

Fetches a public web page and returns its title, meta description, outbound links and readable plain text as JSON.

## Output

A JSON object containing: HTTP status code, final URL after redirects, full redirect chain, server identifier, content type, response time in ms, SEO fields (title, meta description, h1 count, canonical, og:title, og:image, viewport, html lang, robots), TLS certificate details (issuer, subject, validity dates, days remaining, authorization status), and a breakdown of present and missing security headers (HSTS, CSP, X-Frame-Options, etc.).
