How this service works

Output
Returns the text content of definition description (dd) elements extracted from the provided URL or HTML, with SSRF protection ensuring only safe public pages are accessed.
Example use cases
Glossary term descriptions from webpage
“Go to https://developer.mozilla.org/en-US/docs/Web/HTML/Element/dl and pull out all the definition description (dd) text from the page for me.”
Parse dd elements from raw HTML
“I have this HTML snippet with a definition list — can you extract just the dd element text from it? Here's the HTML: <dl><dt>Term</dt><dd>This is the description</dd></dl>”
Scrape product spec descriptions
“Fetch https://example.com/product-specs and give me all the definition description (dd) values listed on that page — I want to pull the spec details.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/css-dd?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to extract definition description (dd) element content from a public web page or raw HTML string. It is SSRF-safe, making it appropriate for processing URLs supplied by users or external sources. Prefer the free POST /v1/sandbox/css-dd endpoint for testing; use this paid endpoint for production usage. Choose this over general-purpose HTML parsers when you specifically need dd element content from definition lists.
Side effects
- URL is unreachable or returns non-200 status — extraction fails with an error
- HTML input exceeds 200,000 character limit — rejected with validation error
- URL points to an internal/private network resource — blocked by SSRF protection
- No dd elements found in the page or HTML — returns empty result
- Malformed HTML that cannot be parsed — may return empty or partial result
- URL shorter than 8 characters or longer than 2048 characters — rejected by schema validation
