The x402 integration enables pay-per-use browser sessions using cryptocurrency. Built on the x402 protocol, this integration lets you create and manage Browserbase sessions by paying with USDC on Base, with no API keys or accounts required.
This integration uses the HTTP 402 Payment Required status code to enable seamless crypto payments for browser automation.

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 from Tools for Humanity.

Standard x402 session

Pay with USDC, get a working browser. No account or identity required.

Verified x402 session

Add an AgentKit proof header to unlock Verified browsers.
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.

Set up AgentKit verification

Learn how to prove your agent is human-backed and unlock premium features
