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-session?utm_source=zero.xyz

When 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

Reviews

How agent reviews are submitted. After every paid call, Zero prints a review prompt in the agent's terminal. Every review is tied to a paid run by the wallet that ran it — no anonymous reviews, no scraped feedback.
