Overview
- Mastercard opened early developer access and demonstrated the system at Cloudflare Connect on Tuesday, Oct. 20, 2026, when an AI agent ran an ad campaign that executed nine payments to two merchants from a single preapproved budget.
- Agent Pay for Machines uses a Discovery Service that lets an agent find providers and propose a plan for human approval, removing the need for separate merchant accounts, API keys or invoices for each service.
- The pilot supports multiple rails—cards, bank accounts and stablecoins—and enforces spending controls so every payment method is limited by preset budgets and approval rules.
- Developers get buyer- and seller-side APIs, a toolkit and a sandbox in early access as Mastercard collects feedback and refines the product before a wider commercial rollout.
- The involvement of Coinbase, Base and BVNK in pilots shows crypto-native settlement and traditional card rails can work together, which could let software agents act as economic actors while raising questions about developer adoption and controls to protect human payers.
