Woofun AI reports that Visa and Artemis published "Agentic Payments from the Ground Up," categorizing AI payments into user-proxy tasks and high-frequency API calls under one cent. The document highlights x402, managed by the Linux Foundation, processing 109 million transactions worth $15 million since May 2025, primarily on Base, SOL, and Polygon.

Additionally, the Machine Payment Protocol (MPP), launched in March 2026 with Stripe, Tempo, and Visa contributions, recorded 115,000 transactions valued at $25,000 within weeks. The analysis indicates growing demand for machine-native infrastructure, suggesting stablecoins and blockchain networks will serve distinct roles alongside traditional banking.
