Agent Hub Web Page Structured Data Extractor

Choose this endpoint when you need to extract structured, typed data from a live web page rather than raw HTML or plain text. It is particularly valuable when the page is JavaScript-rendered (React, Vue, etc.) since it uses a headless browser, and when you want LLM-assisted field mapping rather than writing CSS selectors manually. Prefer it over a CSS-selector scraper when you don't know the exact DOM structure in advance, or when a plain-English description of the fields is more practical than a hand-crafted selector list.

• URL is inaccessible, behind a login wall, or returns non-200 — extraction may fail or return empty fields
• Page uses heavy anti-bot measures (Cloudflare, CAPTCHA) — headless browser may be blocked
• Schema or prompt is ambiguous — LLM may misinterpret field intent and return incorrect values
• Dynamic content loaded after initial render may not be captured depending on render timing
• Malformed JSON schema input causes a parsing error and the call fails
• Rate limiting or network timeout on the target page leads to empty or partial results
