Example prompt: Can you run a full SEO audit on https://www.example.com — I want to see how the title, meta description, H1s, image alt tags, canonical, robots.txt, sitemap, Open Graph, and schema.org markup all look?

## When to prefer this

Use this endpoint when you need a broad, multi-factor on-page SEO health check for a single URL in one call, covering technical SEO signals (robots.txt, canonical, sitemap), metadata quality (title, meta description, H1), social metadata (Open Graph), structured data (schema.org), accessibility signals (alt tags), and link profile — all in a single request rather than running separate specialized tools.

## Known failure modes

- URL is unreachable or returns a non-200 status — audit may fail or return partial results
- URL is missing the required query parameter — returns a validation error
- The target page blocks crawlers via robots.txt or headers — some checks may be incomplete
- Malformed or non-HTTP URL provided — returns an input error
