How this service works
Definition descriptions — Joined text extraction: Joined text extraction for Definition descriptions. 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 joined text extraction result.
Output
A single bounded joined text string concatenating all matching definition description (dd) element text nodes found on the page or in the supplied HTML, filtered by the specified term and optional attribute/attribute-value selector. Returns one result per call.
Example use cases
Glossary term extraction from docs site
“Pull all the definition description text for the term 'authentication' from https://docs.myplatform.com/glossary — filter to dd elements where the class attribute is 'definition', and skip any text we already have like 'Basic auth description'.”
Product spec parsing from e-commerce HTML
“Here's the raw HTML of a product listing page — extract all the joined dd element text related to the term 'dimensions', looking for elements where the data-kind attribute equals 'spec'. Return the combined text from all matching definition descriptions.”
Automated definition harvesting for knowledge base
“Scrape the definition descriptions for the term 'warranty' from https://shop.example.com/products/widget — specifically grab dd elements where the name attribute is 'warranty-details', and exclude anything from this list of texts we already captured last week: 'Standard 1-year coverage', 'Extended plan available'.”
Technical details
Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-bx-web-definition-text-text?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to extract text specifically from HTML definition description (dd) elements on a static, publicly accessible web page or from directly supplied HTML markup. It is well-suited for glossaries, product specification tables, and structured definition lists. Prefer this over generic text extractors when you need targeted dd-element parsing with term and attribute filtering, and when the page does not require JavaScript rendering or authentication.
Side effects
- URL unreachable or returns non-200 status — extraction fails with no result
- Page requires JavaScript rendering — static parser returns empty or incomplete results
- No dd elements matching the term or attribute filter found — returns empty joined text
- HTML input exceeds 100,000 character limit — request rejected
- Attribute name does not match pattern requirements — validation error
- URL exceeds 2048 character maximum — request rejected
- Login-protected or paywalled content — parser cannot access content behind authentication
