Mastercard launched Agent Pay for Machines (AP4M) on Wednesday, extending its payments network to autonomous AI agents. The network supports settlement via cards, bank accounts, and stablecoins, with over 30 crypto and fintech launch partners including Coinbase, RippleX, Solana Foundation, Polygon, Aave Labs, and Stellar.
Ripple simultaneously released the XRPL AI Starter Kit, giving developers tools to build AI-agent payment applications on the XRP Ledger using XRP and RLUSD. The launch coincided with Mastercard naming Ripple as a partner in the agentic-commerce network, signaling deepening ties between traditional payments infrastructure and crypto rails.
The initiative opens Mastercard's global card network to programmatic AI spending, potentially accelerating adoption of crypto-based micropayments for autonomous services such as data queries, compute resources, or API calls. No specific pricing or fee structures for the service have been disclosed by Mastercard.
The move places Mastercard alongside Visa in exploring programmable money for machines, though Visa has not announced a comparable agentic-commerce initiative. Regulatory clarity around AI-agent payments remains nascent; the SEC has not issued guidance on whether such transactions fall under securities laws when stablecoins are involved.
Critics argue that AI-agent payments introduce novel risks around authorization, fraud liability, and consumer protection — particularly when an agent autonomously commits funds without human oversight. Mastercard has not detailed how dispute resolution or chargeback mechanics would function in fully autonomous scenarios.
