How this service works
Call when an agent needs label text via label from a public page or HTML (SSRF-safe). Exact $0.008 USDC. Prefer unpaid POST /v1/sandbox/css-label first.
Output
Returns the matched text content of the CSS-selected label element from the provided URL or HTML string. Typically a short string representing the visible label copy found in the DOM.
Example use cases
Scrape product label from retailer page
“Fetch the price label text from https://example-shop.com/product/42 — it's the element with class 'price-tag', and I need the raw text value displayed there.”
Extract form field label from pasted HTML
“Here's some HTML from a form I'm building: <label for='email' class='field-label'>Your email address</label> — can you pull out just the text content of the label with class 'field-label'?”
Pull header label text from public dashboard
“Go to https://dashboard.example.org/status and extract the text inside the element with id 'status-label' so I can log the current system status message.”

Endpoint

Use this endpoint when an agent needs to extract the visible text content of a specific element identified by a CSS selector from either a live public URL or raw HTML string, and SSRF safety is required. Prefer the free sandbox variant (POST /v1/sandbox/css-label) for testing. Choose this paid endpoint for production workloads or when the sandbox is unavailable.

- HTML input exceeds 200,000 character limit
- URL is shorter than 8 characters or malformed
