How this service works
Call when an agent needs definition term text via dt from a public page or HTML (SSRF-safe). Exact $0.003 USDC. Prefer unpaid POST /v1/sandbox/css-dt first.
Output
Returns the text content found within HTML dt (definition term) elements from either a fetched public URL or provided raw HTML, delivered as extracted text strings.
Example use cases
Glossary term extraction from docs site
“Pull all the definition terms from this HTML documentation page at https://docs.example.com/reference so I can build a glossary index from the dt elements.”
Definition list parsing from raw HTML
“Here's the raw HTML of a product spec page — can you extract all the dt element texts from it so I know what properties are being defined?”
Structured data scraping from public wiki
“Go to https://en.example.org/wiki/Terminology and extract all the definition terms (the dt tags) so I can map them out in a table.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/css-dt?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to extract definition term (dt) text from HTML definition lists, either from a live public URL or raw HTML content, with built-in SSRF protection. Prefer this over generic HTML parsers when you specifically need dt elements and want a lightweight, paid-per-call microservice. Use the free sandbox endpoint POST /v1/sandbox/css-dt first if available.
Side effects
- URL is inaccessible or returns non-200 status
- SSRF check blocks private/internal IP addresses or localhost URLs
- HTML contains no dt elements, returning empty result
- HTML input exceeds 200,000 character limit
- URL exceeds 2,048 character length limit
- Malformed HTML may cause incomplete dt extraction
- Network timeout when fetching remote URL
