Product guide metadata extraction
“I have this HTML snippet with a <dd> element for the term 'widget' — can you pull out the 'id' attribute value from that definition description? Here's the HTML: <!doctype html><html><body><dd id='widget-001' data-type='hardware'>Widget guide</dd></body></html>”

Technical details
Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-bx-web-definition-text-attributes?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to extract a specific HTML attribute value from a definition description element on a static, publicly accessible web page or a provided HTML string, and the page does not require JavaScript rendering or authentication. It is purpose-built for definition list markup (<dd> elements) and is ideal when you know the term you are looking for and the attribute name you want to extract. Prefer this over general-purpose scrapers when your target is specifically HTML attribute data within definition contexts.
Side effects
- No matching <dd> element found for the given term — returns empty or null result
- Attribute not present on the matched element — returns empty string
- URL is inaccessible, paywalled, or requires JavaScript rendering — parsing fails
- HTML exceeds 100,000 character limit — input rejected
- Attribute name does not match allowed pattern (must start with a letter, max 50 chars) — validation error
- Page returns non-HTML content (e.g. JSON, PDF) — parsing fails
