JS Page Renderer

Choose this endpoint when a plain HTTP fetch returns an empty or skeleton HTML shell because the target page is a single-page application (SPA) built with React, Angular, Vue, or similar frameworks. It is the right choice when you need JavaScript to actually execute before content is visible, or when the final URL after client-side redirects matters. For static HTML pages that return full content on a plain GET request, a simpler fetch endpoint would be faster and cheaper.

• URL is not publicly accessible or requires authentication — returns empty or error response
• Page takes too long to render (timeout) — may return partial or no content
• URL is malformed or missing — validation error on required query parameter
• Page actively blocks headless browsers (bot detection) — may return minimal or incorrect content
• Non-HTTP/HTTPS URLs or private network addresses — rejected as invalid input
