How this service works
Aside blocks — Distinct value extraction: Distinct value 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 distinct value extraction result.
Output
Returns a bounded set of distinct (deduplicated) attribute values extracted from <aside> HTML elements matching the given term and attribute filter, parsed statically from the provided URL or raw HTML without JavaScript rendering.
Example use cases
Audit sidebar content types on a docs site
“Go to https://docs.myproduct.com/getting-started and extract all the unique 'data-kind' attribute values from the aside blocks that mention 'guide', excluding anything already seen like 'overview'.”
Scrape unique aside IDs from a product page
“Parse this HTML I'm pasting and give me all the distinct 'id' values from aside elements that contain the word 'product' — skip duplicates and ignore any you've already seen like 'promo-aside'.”
Inventory callout block classes across a landing page
“Fetch https://landing.example.com/features and extract every unique 'class' attribute value from the aside tags that reference 'callout', ignoring ones we already processed like 'callout-basic'.”
Technical details
Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-bx-web-asides-unique?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to collect unique attribute values specifically from HTML <aside> elements (sidebars, callouts, supplementary content blocks) with deduplication built in, and you have a static HTML page or a URL that doesn't require JavaScript to render. Prefer this over generic HTML scrapers when your task is specifically scoped to aside blocks and you want only distinct values relative to a prior seen list.
Side effects
- URL is behind a login wall or requires JavaScript rendering — static parser returns empty results
- No aside elements found matching the term or attribute filter — returns empty list
- URL is unreachable or returns a non-200 status — fetch failure error
- HTML input exceeds 100,000 character limit — request rejected
- attribute parameter doesn't match pattern ^[a-zA-Z][a-zA-Z0-9:_-]{0,49}$ — validation error
- previous_texts array exceeds 200 items — request rejected
