Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-bx-web-asides-attributes?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to extract a specific HTML attribute (like id, class, data-*, aria-*) from aside/sidebar elements on a static webpage or known HTML snippet, and you want to filter results by a keyword term. It is ideal for lightweight, no-JavaScript static HTML parsing tasks scoped to aside blocks. Prefer this over a general scraper when your target is specifically aside elements and you want a bounded, cost-efficient single-attribute result.
Side effects

- URL exceeds 2,048 character limit
- Attribute name does not match required pattern (must start with a letter, alphanumeric/colon/underscore/hyphen, max 50 chars)

- Term field is empty or missing (minLength: 1)
