Stripe Launches Crypto Payment System for AI Agents on Base Blockchain

Stripe Brings Payments to the Age of AI Agents

Stripe has launched a new payment system designed specifically for artificial intelligence agents, allowing them to autonomously pay for digital services using cryptocurrency. Announced on the tenth of February twenty twenty-six by Stripe product manager Jeff Weinstein, the feature is currently available in preview.

How x402 Works

The system is built on x402, an open protocol developed by Coinbase that revives the long-dormant HTTP 402 Payment Required status code. When an AI agent attempts to access a paid service, the server responds with a 402 status containing payment details. The agent then sends a signed payment using USD Coin stablecoins on Base, Coinbase's Ethereum layer-two network, and access is automatically granted.

Developers can charge AI agents for API usage, data access, processing power, and MCP calls using Stripe's familiar Payment Intent API. Stripe generates a unique deposit address per transaction, and businesses can track payments in real time through the dashboard, webhooks, or the API. Once confirmed, funds settle into the merchant's standard Stripe balance, with tax reporting, refunds, and compliance handled automatically.

Building the Agent Economy

The launch reflects Stripe's expanding focus on what it calls the agent economy, where software programmes operate independently and manage their own finances. Rather than relying on monthly subscriptions or prepaid credits, services can be priced dynamically per action, per second, or per query.

Base's low fees and fast settlement times make the system well-suited for frequent, low-value transactions. Stripe has also released an open-source command-line tool called purl, along with sample code in Python and Node.js, to help developers test machine payments.

Broader Blockchain Strategy

The integration follows Stripe's wider push into blockchain infrastructure, including its incubation of Tempo, a layer-one blockchain focused on global stablecoin payments. Tempo raised five hundred million dollars at a five billion dollar valuation in October twenty twenty-five and recently opened its public testnet with partners including Mastercard, UBS, and Klarna. Stripe has indicated that more protocols, currencies, and blockchain networks will be supported in the future.
