Example prompt: Can you run an on-page SEO score check on my product landing page? Here's the HTML — check things like title tags, meta descriptions, heading structure, and other on-page factors and tell me what's wrong.

## When to prefer this

Choose this endpoint when you need deterministic, reproducible on-page SEO analysis of a specific page's HTML — especially when you want factual structural checks (title, headings, meta tags, internal links) rather than probabilistic domain authority or backlink scores. Ideal for CI/CD SEO gates, pre-publish audits, or comparing on-page quality across pages without relying on third-party crawl data. Prefer alternatives if you need open-web authority signals, backlink analysis, or site-wide crawl coverage.

## Known failure modes

- HTML exceeds 512,000 character limit — request will be rejected
- Missing both url and html fields — endpoint requires at least one input
- Malformed or non-HTML content supplied — checks may return incomplete or error results
- Network timeout if HTML is very large and near the size limit
- Invalid URL format if url field is provided — may return validation error

## Output

Returns a structured on-page SEO score and detailed check results for the supplied HTML, covering elements such as title tags, meta descriptions, heading hierarchy, canonical tags, image alt text, and internal link signals — without making claims about domain authority or backlink metrics.
