How this service works

Extract structured data from any web page with full JavaScript rendering. Handles SPAs, dynamic content, and pages that require JS to load.

Output

Returns structured data as specified by the natural language extraction instruction, pulled from the fully JavaScript-rendered version of the target URL. Fields are extracted and returned in a structured format matching the requested entities.

Example use cases

Example prompt

“Go to https://example.com/products/laptop-x and extract the product name, price, availability, and technical specifications — the page uses JavaScript to load its content.”

Technical details

Endpoint

POSThttps://api.strale.io/x402/web-extract?utm_source=zero.xyz

When to prefer

Choose this endpoint when the target web page uses JavaScript frameworks (React, Vue, Angular) or dynamic loading that means a plain HTTP fetch would return empty or skeleton HTML. Ideal for SPAs, infinite scroll pages, or any page where content only appears after JS execution. If the page is static HTML, a simpler HTTP-based scraper may be faster and cheaper.

Side effects

URL is unreachable or returns a non-200 status — extraction fails with an error
Page requires authentication or login — returns empty or partial data
JavaScript rendering timeout — page may load but dynamic content not fully populated
Malformed URL input — returns validation error
Extraction instruction too vague — may return incomplete or mismatched fields
Anti-bot measures block the renderer — returns empty or error response
