How this service works
Call when an agent needs text of elements with role via //*[@role] from a public page or HTML (SSRF-safe). Exact $0.005 USDC. Prefer unpaid POST /v1/sandbox/xpath-role first.
Output
Returns the text content of all HTML elements matching `//*[@role]` — i.e. every element in the document that has a `role` attribute — extracted from either the given public URL or the supplied raw HTML. Results typically include element texts, their role values, and positional context.
Example use cases
Audit ARIA roles on a live site
“Go to https://mycompany.com and extract all the text content from every element that has a role attribute — I want to audit our ARIA accessibility markup.”
Extract navigation and landmark text from HTML
“I have this HTML snippet and I need you to find every element with a role attribute and return their text content — here's the HTML: <nav role='navigation'>...</nav><main role='main'>...</main>”
Scrape structured semantic regions from a public page
“Fetch https://news.ycombinator.com and give me the text inside all elements that carry an explicit role attribute so I can see how they've structured their semantic regions.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/xpath-role?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to extract text from ARIA role-attributed elements from a live public URL or raw HTML and are willing to pay $0.005 USDC per call. Prefer the free sandbox endpoint POST /v1/sandbox/xpath-role for testing. Choose this over general-purpose scrapers when you specifically need `//*[@role]` XPath targeting with SSRF safety guarantees.
Side effects
- URL is not publicly accessible or returns non-200 status
- SSRF-blocked URL (private IP ranges, localhost) rejected for security
- HTML input exceeds 200,000 character limit
- No elements with a role attribute found — empty result set
- Malformed HTML that cannot be parsed
- URL string shorter than 8 characters or longer than 2048 characters
- Payment of exactly $0.005 USDC not provided or fails
