Browser render

Render a page in a real headless Chromium browser (JavaScript executed), then extract the main content as clean markdown. Use this for SPAs and JS-heavy sites where plain fetching returns an empty shell.

Input

Field	Type	Description
url *	string	Public http(s) URL to render

Example output

{
  "url": "https://example.com/spa-page",
  "title": "Page title",
  "wordCount": 500,
  "markdown": "…",
  "rendered": true
}

Try it — see the 402 challenge (free)

curl -i -X POST https://agent402.tools/api/render \
  -H "Content-Type: application/json" \
  -d '{"url":"https://example.com/spa-page"}'

The response is HTTP 402 Payment Required with exact payment requirements. Any x402 v2 client pays automatically and retries:

Paid call (JavaScript agent)

import { wrapFetchWithPayment } from "@x402/fetch";
import { x402Client } from "@x402/core/client";
import { registerExactEvmScheme } from "@x402/evm/exact/client";
import { privateKeyToAccount } from "viem/accounts";

const client = new x402Client();
registerExactEvmScheme(client, { signer: privateKeyToAccount(KEY) });
const payFetch = wrapFetchWithPayment(fetch, client);

const res = await payFetch("https://agent402.tools/api/render", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({
    "url": "https://example.com/spa-page"
  }),
});
