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 — no API keys or accounts required.
This integration uses the HTTP 402 Payment Required status code to enable seamless crypto payments for browser automation.
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 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
