## When to prefer this

Choose this endpoint when you need fast, lightweight static extraction of a page title HTML fragment from a public URL or raw HTML string, without JavaScript rendering. It is ideal for SEO audits, metadata collection, or content monitoring on publicly accessible static pages. Prefer it over full browser-based scraping tools when the page title is rendered server-side and no authentication is needed.

## Known failure modes

- URL is unreachable or returns a non-200 status — extraction fails with no result
- Page requires JavaScript rendering to display content — static parser returns empty or incomplete fragment
- Attribute or attribute_value does not match any element in the HTML — returns empty result
- Supplied HTML exceeds 100,000 character limit — request rejected
- URL exceeds 2,048 character limit — request rejected
- Login-protected or access-restricted pages cannot be accessed — no bypass is attempted
