Browserbase Enables Native Agentic Browser Sessions with x402 and USDC

By: Kevin Leffew

Tl;dr: Browserbase launched an x402 endpoint allowing AI agents to buy and launch browser sessions with USDC on Base, no config needed.

Today we’re excited to share that Browserbase has launched an x402 endpoint, enabling AI agents to natively purchase  their hosted browser sessions. Through the x402 Bazaar and Payments MCP, agents can discover Browserbase, view pricing, and pay per session using USDC on Base – eliminating the need for API keys, billing portals, or manual onboarding.

This is a big unlock for the emerging agentic stack: agents can finally browse, click, fill forms, and interact with the web using a real browser, paid for automatically, as part of their workflow.

What is Browserbase?

Browserbase provides developers with serverless, programmable browsers that run in secure cloud environments. It gives agents and automation systems full control over a real Chromium browser: navigation, DOM access, screenshot capture, replay, cookies, storage, and more.

AI developers use Browserbase to power:

• web scraping that needs JavaScript execution

• automated workflows that interact with legacy web apps

• QA pipelines that require a real browser for user simulation

• e-commerce and checkout automation

• “internet-native” agents that need to see and interact with the actual web

The x402 Endpoint Unlock

1. Autonomous Web Navigation

Agents can browse, click, extract DOM data, and capture screenshots in real browsers. This is useful for research, shopping, and live data retrieval workflows.

2. Automated QA & Regression Testing

Agents can run test suites in isolated browser environments, capturing screenshots, DOM snapshots, console logs, and network traces, for CI pipelines.

3. E-commerce Automation

Agents can complete multi-step e-commerce flows, including adding items to carts, filling forms, applying promo codes, and comparing prices. Payments for sessions are handled automatically via x402.

4. Legacy Integration for Systems With No API

For older web apps without APIs, agents can interact directly with the UI. x402 simplifies the process: “Call endpoint → run browser → pay USDC → get results.”

Browserbase, Powered by Coinbase Business

Browserbase uses Coinbase Business as its settlement layer for x402 payments. Each session payment in USDC is instantly deposited into their Coinbase account, offering:

• automatic rewards on idle balances

• institutional-grade custody

• real-time revenue tracking

• no reconciliation work or fraud risk

• no credit cards to manage

This lets Browserbase emphasize its focus on delivering reliable and robust browser infrastructure.

Get Started

Developers and agent builders can start experimenting today:

• Demo: https://www.x402scan.com/server/d6e9dbe6-b4be-40ee-bd9d-a160b3011ae2

With Browserbase and x402, agents can directly pay to access and use the web itself.  Navigation, interaction, and execution all become metered, autonomous actions - with no accounts, API keys, or human setup.

If you’re building agents, automation systems, or AI-native products that need real browser interaction, now is the perfect time to explore.
