NAME

browser-session — loads a url in a real headless browser with javascript executed, then returns the rendered html and page title, or a base64 screenshot

SYNOPSIS

POST https://x402.agentutility.ai/browser-session
     Content-Type: application/json
     X-PAYMENT:    <signed-transferWithAuthorization>

     { ... }

↳ first call → 402 Payment Required. Sign USDCtransferWithAuthorization, retry with theX-PAYMENT header.

DESCRIPTION

Loads a 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, full-page screenshot API, or to scrape JS-heavy sites and get the post-JavaScript DOM.

INPUT — request schema

property	type	description	req?
url	string	Absolute http(s) URL to render.	required
screenshot	boolean	Return a base64 PNG screenshot instead of HTML. Default false.	optional
full_page	boolean	When screenshot=true, capture the full scrollable page. Default false.	optional
wait_ms	number	Extra milliseconds to wait after load for late JS (0-10000). Default 0.	optional

EXAMPLES — two ways to call

EXAMPLE 1 · curl

curl -X POST https://x402.agentutility.ai/browser-session \
  -H 'Content-Type: application/json' \
  -d '{ }'

first response = 402 Payment Required with payment requirements; sign + retry with X-PAYMENT.

EXAMPLE 2 · mcp

# Install the MCP package for this endpoint's cluster
npx -y @agentutility/mcp-<cluster>

# Required: EVM private key with USDC on Base
export X402_PRIVATE_KEY=0x...

# Then call the browser-session tool from your MCP-aware agent.

MCP server handles payment automatically — your coding agent just calls the tool by name.
