The line between autonomous software and economic actor just got thinner. Coinbase confirmed this week that corporate customers on its platform can now accept payments directly from AI agents, a move that turns machine-to-machine transactions from a concept into a commercial feature. The capability, rolling out to business users, relies on the x402 protocol, an open standard developed and incubated by the exchange. The original report from CoinDesk details how the feature lets companies receive payment for services rendered to AI systems without a human in the loop.
