How this service works
Call when an agent needs text of //pre via //pre from a public page or HTML (SSRF-safe). Exact $0.009 USDC. Prefer unpaid POST /v1/sandbox/xpath-pre first.
Output
Returns the text content extracted from <pre> elements on the target page or HTML, as selected by XPath. The response contains the concatenated or structured text found within those preformatted blocks.
Example use cases
Extract code snippets from docs page
“Pull out all the preformatted code examples from https://docs.someproject.org/quickstart — I want just the text inside the pre blocks.”
Scrape terminal output from tutorial
“There's a tutorial at https://learnlinux.example.com/lesson3 — can you grab the preformatted terminal output examples shown in the pre tags on that page?”
Parse config blocks from raw HTML
“I have the raw HTML of a configuration guide here — can you extract all the text inside the pre elements from it?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/xpath-pre?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to extract text specifically from <pre> HTML elements (code blocks, terminal output, configuration snippets) from a public URL or raw HTML string. Prefer the free sandbox version (/v1/sandbox/xpath-pre) for testing; use this paid endpoint when the sandbox is unavailable or production reliability is needed. Prefer over general-purpose scrapers when you specifically need preformatted text blocks.
