How this service works
Call when an agent needs cite text via cite from a public page or HTML (SSRF-safe). Exact $0.001 USDC. Prefer unpaid POST /v1/sandbox/css-cite first.
Output
A list of text strings extracted from all <cite> elements found in the provided URL's HTML or the supplied raw HTML. Returns citation text content suitable for downstream citation analysis, reference listing, or content auditing.
Example use cases
Extract citations from research article
“Grab all the cited sources from this article page at https://www.nature.com/articles/s41586-023-06473-y — I want to see every <cite> tag's text.”
Parse citations from pasted HTML
“I have some raw HTML from a webpage — can you extract all the citation text out of it? Here's the HTML: <article><p>According to <cite>Smith et al. 2021</cite> and <cite>Jones 2019</cite>, the results are significant.</p></article>”
Audit citation markup on a news page
“Check the BBC article at https://www.bbc.com/news/technology-65855333 and list everything marked up as a <cite> element on that page.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/css-cite?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to extract <cite> element text from a public webpage or HTML blob in an SSRF-safe way. Prefer the free sandbox variant (POST /v1/sandbox/css-cite) for testing before incurring the $0.001 USDC cost. Choose this over generic HTML scrapers when you need just citation elements without full-page content, and when SSRF safety is a requirement.
Side effects
- URL is not publicly accessible or returns a non-200 status — extraction fails
- SSRF protection blocks private/internal IP ranges — request rejected
- HTML contains no <cite> elements — returns empty list
- HTML exceeds 200,000 character limit — request rejected
- URL string is malformed or under 8 characters — validation error
- Network timeout fetching the target URL — request fails
