How this service works
Call when an agent needs text of //dd via //dd from a public page or HTML (SSRF-safe). Exact $0.009 USDC. Prefer unpaid POST /v1/sandbox/xpath-dd first.
Output
Returns the text content matched by the XPath expression, either fetched from the given public URL (SSRF-safe) or evaluated against the provided raw HTML. The response contains the extracted text nodes or attribute values selected by the XPath query.
Example use cases
Price monitoring from product page
“Grab the price text from https://shop.example.com/product/42 using the XPath //span[@class='price'] — I want to track whether it changes.”
Extract article body from news site
“Pull out the main article text from https://news.example.com/story/123 using the XPath //div[@id='article-body']//p and give me all the matched paragraph text.”
Scrape table data from public HTML
“I have this HTML snippet of a government stats table — can you run the XPath //table[@id='stats']//tr/td[2] on it and return all the values in that second column?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/xpath-dd?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to extract a specific piece of text or data from a webpage or HTML document using a precise XPath selector, especially when you already know the document structure. It is preferable over full-page scraping when only a targeted node is needed. If you have raw HTML locally, pass it directly; if you need the page fetched, pass the URL and rely on its SSRF-safe fetching. Use the free sandbox variant /v1/sandbox/xpath-dd first for development.
Side effects
- Invalid or malformed XPath expression returns a parsing error
- URL points to a private/internal IP address and is rejected by SSRF protection
- URL is unreachable or returns a non-200 status, causing a fetch failure
- HTML content exceeds 200,000 character limit, resulting in rejection
- XPath matches no nodes, returning an empty result
- Malformed HTML may cause unpredictable XPath evaluation results
