# x402 protocol integration

> Pay-per-use browser sessions with crypto. No API keys, no accounts—just pay and connect.

The **x402 integration** enables pay-per-use browser sessions using cryptocurrency. Built on the [x402 protocol](https://x402.org), this integration lets you create and manage Browserbase sessions by paying with USDC on Base — no API keys or accounts required.

<Info>
  This integration uses the HTTP 402 Payment Required status code to enable seamless crypto payments for browser automation.
</Info>

**Endpoint:** `https://x402.browserbase.com`

## Premium features with AgentKit

By default, x402 sessions use a standard browser. To unlock **Verified browsers** — the same premium feature available to Scale plan customers — your agent can prove it's human-backed using [AgentKit](/integrations/agentkit/introduction) from Tools for Humanity.

<CardGroup cols={2}>
  <Card title="Standard x402 session" icon="browser">
    Pay with USDC, get a working browser. No account or identity required.
  </Card>

  <Card title="Verified x402 session" icon="shield-check">
    Add an AgentKit proof header to unlock Verified browsers.
  </Card>
</CardGroup>

This creates a layered access model: anyone can pay for a browser, but premium features are reserved for agents that can cryptographically prove human backing. No API keys, no KYC — just math.
