How this service works
Call when an agent needs text of //cite via //cite from a public page or HTML (SSRF-safe). Exact $0.005 USDC. Prefer unpaid POST /v1/sandbox/xpath-cite first.
Output
Returns the text content found at the specified XPath location within the fetched page or provided HTML, as a plain string citation extracted safely without SSRF risk.
Example use cases
Cite a news article headline
“Grab the exact headline text from https://reuters.com/world/some-story using XPath //h1[@class='article-header__title'] so I can cite it in my report.”
Extract a terms-of-service clause
“I need the exact wording of section 3 from https://example.com/terms — can you pull it using XPath //section[@id='section-3']/p?”
Scrape a product price from a public page
“Get the price text from https://shop.example.com/product/widget using XPath //span[@class='price'] — I want to know the exact number shown on the page.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/xpath-cite?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to extract a specific, precisely located text fragment from a public webpage or raw HTML using an XPath expression, especially in agentic workflows where SSRF safety is required. Prefer this over generic scrapers when the target element is addressable by XPath and exact citation is important. Use the free sandbox variant (/v1/sandbox/xpath-cite) first to validate your XPath before paying.
Side effects

- HTML exceeds the 200,000 character limit
