How this service works
Definition descriptions — Text length statistics: Text length statistics 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 text length statistics result.
Output
Returns bounded text length statistics (such as min, max, mean, or character counts) for definition description elements matching the specified term, attribute, and attribute value on the given page or HTML. Optionally compares results against a set of previously supplied texts.
Example use cases
Glossary content length audit
“Go to https://docs.mycompany.com/glossary and calculate text length statistics for all definition descriptions where the data-kind attribute equals 'technical', using 'API' as the search term — I want to see how our current descriptions compare to these older ones: ['An interface for software', 'A communication protocol'].”
Product guide description QA
“Parse this HTML and give me length statistics for the definition descriptions with id 'product' where the term is 'guide': <!doctype html><html><body><dd id="product" data-kind="guide">A comprehensive walkthrough for new users.</dd></body></html>”
Before-and-after content revision check
“Fetch https://store.example.com/help/definitions and compute text length statistics for definition descriptions where the class attribute is 'item-desc' and the term is 'item', then compare against my previous versions: ['Short old description', 'Another older one', 'Third legacy text'].”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-bx-web-definition-text-lengths?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need statistical analysis of text lengths specifically for HTML definition description (dd) elements on a public page or supplied HTML snippet, especially when filtering by attribute and comparing against historical text baselines. It is purpose-built for this niche task rather than a general text extraction tool.
Side effects
- URL is unreachable or returns non-200 response — parsing fails with an error
- HTML too large (over 100,000 characters) — request rejected
- No matching definition description elements found — empty or zero-count statistics returned
- JavaScript-rendered content not visible — static parser cannot access dynamically loaded dd elements
- Invalid attribute name format — schema validation error
