## 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 quickbuild-web-audit-api-e937e306
```

Example prompt: Can you run a web audit on https://mysite.com and give me a JSON summary of all security header issues and other problems, grouped by severity?

## When to prefer this

Choose this endpoint when you need a fast, per-URL web audit covering security headers, broken links, and sitemap issues without setting up your own crawler. It is ideal for one-off site checks, pre-launch QA, or automated pipelines where you need structured severity-bucketed output in JSON, HTML, or CSV. Prefer this over general-purpose scrapers when the goal is specifically web quality and security analysis rather than raw content extraction.

## Known failure modes

- Private or reserved IP addresses rejected with an error
- Invalid or malformed URL returns a validation error
- Unreachable URLs (network timeout or DNS failure) produce an error response
- Non-HTTP/HTTPS URLs are refused
- Rate limiting or per-call payment failure blocks the request

## How this service works

Landing pages ($15), Google Sheets/Apps Script automation ($10), scrapers, scripts & Telegram bots (from $15), broken-link + sitemap audit reports ($10). See a working demo first, pay after.

## Output

A JSON (or HTML/CSV) object containing a list of issues, each with an area (e.g. 'security-headers'), a message (e.g. 'HSTS missing'), and a severity level (critical, high, medium, low, info), plus a summary object with counts per severity tier.
