Example prompt: Can you extract all aside block excerpts containing the term 'pricing' from https://example.com/product-page — look in the aside element with id 'sidebar'?

## When to prefer this

Choose this endpoint when you need to extract contextual text excerpts specifically from HTML aside elements (sidebars, callouts, notes) that contain a particular term, using only static HTML parsing. Ideal for documentation sites, content portals, and structured webpages where asides carry supplementary context. Not suitable for pages requiring JavaScript rendering or authentication.

## Known failure modes

- URL is behind a login or paywall — only public pages are supported
- JavaScript-rendered aside content will not be captured since rendering is not performed
- Term not found in any aside blocks — returns empty result
- Invalid or unreachable URL returns an error
- HTML input exceeds 100,000 character limit
- Attribute pattern does not match the regex constraint causing validation failure
