Mastercard has launched a new payments infrastructure called Agent Pay for Machines (AP4M), designed to allow autonomous artificial intelligence agents to execute high-frequency, low-value transactions without human involvement. The system enables continuous, real-time payments across cards, bank accounts, and stablecoins.
The network introduces credentialing for AI agents alongside programmable permission settings, allowing organizations to define spending limits and authorization rules automatically. Mastercard said the platform is built to bypass inefficiencies in legacy payment rails, which struggle to handle the scale and speed of microtransactions.
Built for machine-to-machine commerce
The rollout comes as machine-driven activity accelerates, with global Internet of Things connections projected to reach 21.9 billion by 2026. These systems are expected to generate massive volumes of data and require payment infrastructure capable of supporting constant, small-value transfers, sometimes worth fractions of a cent.
AP4M is designed to meet that demand with an “always-on” model, contrasting with traditional payments initiated manually for discrete purchases. The system integrates blockchain-based settlement with conventional financial channels, allowing transactions to move seamlessly across different payment methods.
Backed by major crypto and tech partners
At launch, Mastercard collaborated with more than 30 technology firms to test applications and establish industry standards. Early partners include Aave Labs, Alchemy, Anchorage Digital, BVNK, Polygon, Ripple, Solana, Checkout.com, and Cloudflare.
The involvement of major blockchain networks signals growing alignment between traditional financial infrastructure and on-chain ecosystems, particularly as machine-driven transactions emerge as a new source of activity.
Expansion of stablecoin settlement
Mastercard has also expanded its global crypto payments framework, enabling settlement through stablecoins such as USDC, PYUSD, and RLUSD. The company has developed a partner network that connects blockchain settlement layers with traditional payment systems, particularly for cross-border transfers and business payments.
The move reinforces stablecoins’ role as a settlement mechanism beyond trading, positioning them as a core component of automated, programmatic commerce.
Broader push into digital assets and AI payments
The AP4M launch is part of a broader strategy to integrate blockchain and AI into mainstream financial services. In March, Mastercard agreed to acquire stablecoin infrastructure firm BVNK for up to $1.8 billion and secured a New York BitLicense, expanding its regulated digital asset operations.
According to the company, the new infrastructure aims to support emerging AI-driven business models that rely on continuous, machine-to-machine transactions. For market participants, the development highlights a shift toward enterprise-scale blockchain integration, with attention now turning to which networks capture meaningful transaction volume from this new category of activity.
