How this service works
Call when an agent needs text of //dt via //dt from a public page or HTML (SSRF-safe). Exact $0.008 USDC. Prefer unpaid POST /v1/sandbox/xpath-dt first.
Output
Returns the text content of all //dt (definition term) elements found in the page fetched from the provided URL or in the supplied HTML, delivered as structured text output. The extraction is SSRF-safe when fetching remote URLs.
Example use cases
Glossary term extraction from docs
“Can you pull all the definition terms from https://docs.example.com/reference/glossary — I want every //dt element's text so I can build a list of all defined terms on that page.”
Scraping spec metadata fields
“I have some raw HTML from a W3C spec page — can you extract all the //dt elements from it? Here's the HTML: <dl><dt>Author</dt><dd>Jane</dd><dt>Version</dt><dd>1.0</dd></dl>”
Monitoring definition keys on a product page
“Go to https://schema.org/Product and extract all the //dt text nodes — I want to see every property name listed in their definition list.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/xpath-dt?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to extract text specifically from HTML definition term (dt) elements via XPath from a public URL or raw HTML. Prefer the free /v1/sandbox/xpath-dt endpoint first for testing; use this paid endpoint ($0.008 USDC) for production workloads. Choose this over general-purpose scrapers when you specifically need //dt XPath targeting with SSRF safety guarantees.
Side effects
- URL is unreachable or returns non-200 status — extraction fails with an error
- No //dt elements found in the page — returns empty result
- HTML string exceeds 200,000 character limit — request rejected
- URL string shorter than 8 or longer than 2048 characters — validation error
- SSRF-blocked URL (private IP ranges, internal hosts) — rejected for security
- Malformed HTML may result in incomplete or unexpected extraction
