x402 Payments on Base Pass 138 Million as Agent Spending Expands

Cumulative payments through x402 on Base topped 138 million by the third quarter of 2026, as developers funded AI agents to pay for online services, computing power and data. The count rose from about 1,500 in mid-2025. More than 87% of transactions were under 10 cents, an amount at which card processing fees can exceed a service’s price. The x402 protocol lets software agents pay for online services with crypto without requiring a person to approve each purchase.
