Technical details
Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-bx-web-articles-attributes?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to extract a specific HTML attribute from article elements on a public, statically-served webpage or a known HTML snippet, without needing JavaScript rendering, login bypass, or full-page crawling. It is ideal for structured metadata extraction (IDs, data-* attributes, class names) from article tags specifically, at low cost per call.
Side effects
- URL is behind a login or paywall — static parser cannot bypass authentication
- Page requires JavaScript rendering — content invisible to static parser
- Attribute name pattern does not match regex (must start with a letter, alphanumeric/colon/underscore/hyphen, max 50 chars)
- No article element matching the given term is found on the page
- URL is unreachable or returns a non-200 HTTP status
- HTML payload exceeds 100,000 character limit
- URL exceeds 2,048 character limit
