How this service works
Aside blocks — HTML fragment extraction: HTML fragment extraction for Aside blocks. One public HTTPS page or supplied HTML; static parsing, no JavaScript rendering, login or access bypass. Specialised preset in a shared 50-profile, 20-operation engine. 0.01 USDC includes one bounded html fragment extraction result.
Output

Example use cases
Sidebar widget extraction from article
“Go to https://docs.example.com/setup and extract the aside block whose id is 'prerequisites' — I need the HTML fragment from that sidebar block, searching for the term 'install'.”
Pull callout box from product page
“From this HTML I'm pasting, find the aside element with data-kind set to 'warning' and extract its content — use 'data-kind' as the attribute and 'warning' as the value, searching for the term 'caution'.”
Deduplicate aside content across crawled pages
“I've already seen these aside texts from earlier pages. Now check https://blog.example.com/post-42 and extract any aside block with attribute 'class' and value 'tip-box' using search term 'tip' — skip any content I've already seen.”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-bx-web-asides-html?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to extract <aside> HTML fragments from static web pages or raw HTML strings by matching on a specific element attribute. It is ideal for pulling sidebar content, callout boxes, supplementary notes, or related-links blocks from article or documentation pages without needing full-page rendering. Prefer this over general-purpose scrapers when you specifically target aside elements and want lightweight, low-cost per-call extraction with deduplication support.
Side effects
- No aside element found matching the given attribute and value — returns empty or null result
- URL is inaccessible, returns a network or HTTP error
- HTML exceeds 100,000 character limit — input truncated or rejected
- JavaScript-rendered content not accessible — only static HTML is parsed
- Invalid attribute name pattern causes validation error
- Term not found within any aside element — no match returned
