AI Agents Drive 14M x402 Transfers Amid Growing Machine-to-Machine Payments

AI agents have initiated 14 million transfers through the x402 protocol over the past 30 days, marking a significant milestone in machine-to-machine payments. The protocol piggybacks on the HTTP 402 'Payment Required' status code and has turned it into a live payment rail.

The majority of these transactions are happening on Base, Coinbase's Layer-2 chain, which is also serving as the primary settlement asset with USDC stablecoins. This setup eliminates volatility issues that would make budgeting impossible for AI agents using assets like ETH or Bitcoin.

x402 has processed a total of 75 million transactions and $24 million in volume over the last 30 days, with an average payment of $0.32. The protocol is not just processing human-initiated transactions; it's handling payments made by AI agents for API calls, compute resources, data feeds, and content.

Visa, Mastercard, and Google are among the heavyweight backers of the x402 Foundation, which was established to govern the protocol. These companies see the potential for AI agent commerce to become a significant transaction category that cannot be served on traditional payment rails.
