AI Agents Drive Millions Of Microtransactions On Base

Artificial intelligence agents have made more than 138 million payments via the x402 protocol on Base, according to a Chainalysis study published on October 14. However, this figure measures the number of transactions, not 138 million dollars: more than 87% of the analyzed operations are worth less than ten cents. The x402 protocol allows an autonomous software to pay directly for an online service without requiring human validation for each expense. Initially developed by Coinbase, it relies notably on stablecoins to settle amounts too small for traditional card networks. The key figures of the study allow measuring the rise of this still experimental economy : These operations are notably used to purchase data, query a programming interface, access an AI model, or have code reviewed.
