Example prompt: Can you instantly check the security headers on my website https://example.com and tell me what's missing or broken, with a score out of 100?

## When to prefer this

Use this endpoint when you need an instant, single-category security header audit without waiting for a full async scan job. It is ideal for quick checks during development, CI/CD pipelines, or generating a focused security section of an SEO report. Prefer the full /scan/full flow if you need scores across all 20 categories simultaneously.

## Known failure modes

- Missing or invalid 'url' query parameter returns an error or empty result
- Target URL is unreachable or returns a non-200 status, leading to incomplete audit
- Malformed URL input causes a parsing error
- Rate limiting or payment failure (402) if the x402 payment header is missing or insufficient
- Some headers may not be detectable if the target uses aggressive caching or CDN edge responses

## How this service works

SEO audit any website — 200 rules across 20 categories: technical health, Core Web Vitals, content quality, AI-GEO signals, accessibility, security headers, structured data, and more. Async job flow: POST /scan/quick or /scan/full → poll GET /status/{job_id} → get JSON result with per-category scores (0–100) and issue lists. Use /brief for an AI action plan, /analyze for free-form SEO questions, or /check/{category} for instant single-category audits.

## Output

Returns a JSON object with a 'category' field set to 'security' (or similar) and a 'result' object containing a numeric score (0–100) and a list of security header issues found on the target URL, such as missing HSTS, CSP, X-Frame-Options, X-Content-Type-Options, or Referrer-Policy headers.
