Stripe launches Machine Payments Protocol to enable AI agents to transact autonomously
Stripe and Tempo unveiled the Machine Payments Protocol on March 18, 2026, designed specifically for AI agents to execute payments automatically. Unlike three decades of failed micropayment attempts, this open-source protocol eliminates human psychology from transactions, allowing autonomous bots to pay for API calls, datasets, and services without hesitation or cart abandonment. Visa, Coinbase, and other players are developing competing frameworks as the agentic economy takes shape.
