How this service works
Call when an agent needs text of elements that have a lang attribute via //*[@lang] from a public page or HTML (SSRF-safe). Exact $0.006 USDC. Prefer unpaid POST /v1/sandbox/xpath-lang first.
Output
Returns the text content of every HTML element matched by the XPath expression //*[@lang] — i.e., any element carrying a lang attribute — from the provided URL or HTML input. Output is a list or structured collection of text strings corresponding to those matched elements.
Example use cases
Detect multilingual sections on a page
“Go to https://www.un.org/en/about-us and pull out all the text content from elements that have a lang attribute — I want to see what language-tagged regions exist on the page.”
Audit internationalization in raw HTML
“I have this HTML snippet and I need you to find every element that carries a lang attribute and return its text — can you run the lang XPath extraction on it?”
Research competitor multilingual content
“Check https://www.apple.com and extract all the text from any element that has a lang attribute set — I'm trying to understand how they structure their multilingual content.”

Endpoint
POSThttps://agentshelf.syntexa.ch/v1/xpath-lang?utm_source=zero.xyzWhen to prefer
Prefer this endpoint when you specifically need to extract text from elements bearing a lang attribute, such as auditing multilingual or internationalized content on a page. Use over generic scraping tools when the XPath //*[@lang] selector is exactly what you need. Consider the free sandbox POST /v1/sandbox/xpath-lang first before spending $0.006 USDC.
Side effects

- HTML payload exceeds 200,000 character limit
- URL string shorter than 8 characters or longer than 2,048 characters
- Malformed or unparseable HTML causing XPath evaluation failure
- Network timeout when fetching the target URL
