Mastercard’s Agent Pay for Machines targets autonomous AI-agent transactions across public blockchains, with more than 30 backers including OKX, Ripple, Coinbase and the Solana Foundation, and support for cards and stablecoins.
Mastercard has launched Agent Pay for Machines, or AP4M, a payments framework for autonomous transactions between AI agents, including high-frequency micropayments worth less than a cent. The company said more than 30 firms are backing the effort, with named participants across disclosures including OKX, Ripple, Coinbase, the Solana Foundation, Stripe, Ant International and Cloudflare. Mastercard said the system records human-granted permissions for AI agents on public blockchains, with Polygon, Solana and Base selected initially, and supports multiple settlement methods including bank cards and stablecoins. OKX said it will connect through its Agentic Wallet and Agent Payments Protocol.
