How this service works
Call when an agent needs text of //address via //address from a public page or HTML (SSRF-safe). Exact $0.001 USDC. Prefer unpaid POST /v1/sandbox/xpath-address first.
Output

Example use cases
Extract product price from e-commerce page
“Pull the text at XPath //span[@class='price'] from https://shop.example.com/item/123 so I can track the current listed price.”
Scrape article headline from news site
“Get the text at //article//h1 from the HTML I'm pasting here — I want just the headline of this news article.”
Extract table cell from public data page
“From https://data.gov.example/table, extract the text at XPath //table[@id='stats']//tr[2]/td[3] — I need that specific cell value.”

Use this endpoint when you need to extract text at a precise XPath location from a public webpage or a known HTML string. It is SSRF-safe and purpose-built for XPath-based extraction without requiring a full browser or LLM. Prefer the free /v1/sandbox/xpath-address endpoint for testing before committing to paid calls.
