## How to call it through Zero

```sh
zero fetch --capability santos-automation-web-page-auditor-aa3c46f3
```

Example prompt: Can you run a full technical audit on https://www.example.com and tell me the performance, SEO, accessibility, and security-header scores along with anything I should fix?

## When to prefer this

Choose this endpoint when you need a quick, multi-dimensional technical health check on a single public web page — covering performance, SEO, accessibility, and security headers in one call — without needing a full site crawl or a heavyweight tool like Lighthouse via headless browser. Ideal for on-demand checks in CI pipelines, content publishing workflows, or agent-driven site monitoring.

## Known failure modes

- URL is not publicly accessible (private, localhost, or behind auth) — audit cannot fetch the page
- Invalid or malformed URL provided — request is rejected
- Target page returns a non-200 status (e.g. 404, 500) — audit may return partial or empty results
- Page load times out — timing data may be incomplete
- URL points to a non-HTML resource (e.g. a PDF or image) — HTML/SEO/accessibility checks may be meaningless

## How this service works

Audit any website for AI Agent Readiness, MCP, llms.txt, OpenAPI, SEO, accessibility and security. Structured JSON with evidence and prioritized fixes.

## Output

Returns numeric 0-100 category scores for performance, SEO, accessibility, and security headers; a list of individual pass/fail checks; detected issues on the page; and plain-English remediation guidance for each problem found.
