How this service works
Loads a public URL in a real headless browser with JavaScript executed, then returns the rendered HTML and page title, or a base64 screenshot. For pages a plain HTTP fetch can't read because the content is built client-side. Use it as a headless browser render API, JavaScript page renderer, dynamic page renderer, screenshot API, or to scrape JS-heavy sites and get the post-JavaScript DOM.
Output
Returns either the fully rendered HTML string and page title after JavaScript execution, or a base64-encoded screenshot of the page — whichever mode is requested. The HTML reflects the post-JS DOM state, making content from client-side rendered frameworks (React, Vue, Angular) accessible.
Example use cases
Extract content from SPA product page
“Scrape the product listing at https://store.example.com/products using a real headless browser — it's a React app and I need the fully rendered HTML so I can pull out the product names and prices.”
Full-page screenshot for visual audit
“Take a full-page screenshot of https://myapp.io/landing and return it as a base64 image so I can see what the page looks like right now.”
Monitor JS-rendered dashboard content
“Fetch the rendered HTML from https://dashboard.example.com/analytics after JavaScript has run — I need the actual data that gets loaded dynamically, not the blank shell that curl returns.”
Technical details
Endpoint
POSThttps://x402.agentutility.ai/browser-sessionWhen to prefer
Use this endpoint when a plain HTTP GET is insufficient because the target page is client-side rendered (React, Vue, Angular, etc.) and the content is injected after JavaScript execution. Prefer it over static fetch tools when you need the real post-JS DOM or a visual screenshot. It is the right choice for scraping SPAs, JS-gated dashboards, or any page where curl returns a blank shell.
Side effects
- URL is unreachable or returns non-2xx — browser session fails or returns empty content
- Page has aggressive bot detection (Cloudflare, CAPTCHA) — rendered HTML may be blocked or incomplete
- Very long page load times may cause timeouts
- JavaScript errors on the target page may produce a partial or broken DOM
- Invalid URL format — request rejected before rendering
