Circle offers Agent Stack suite to enable autonomous AI agents as economic actors.
“• “Agent Stack” is our integrated suite of developer services and financial infrastructure products designed to enable autonomous artificial intelligence agents to function as independent economic actors. Agent Stack consists of four components: (i) Agent Wallets, policy-controlled programmable wallets that allow AI agents to hold, send, and receive USDC within defined permission and spending control parameters; (ii) Circle CLI (Command Line Interface), a programmatic interface through which developers and AI agents can access and build on our broader platform suite, including wallets, payments, and policy management; (iii) Agent Marketplace, a discovery and transaction layer through which AI agents can identify, engage, and pay for services provided by other agents or third-party providers, enabling machine-to-machine commerce; and (iv) Nanopayments, powered by Circle Gateway, a high-frequency micropayment protocol capable of processing USDC transfers in fractional amounts as small as $0.000001 without gas fees, designed to support the low-latency, high-volume transaction patterns characteristic of agentic workflows.”
