A walkthrough of Circle Agent Stack — the chain- and protocol-agnostic infrastructure for the agentic economy. See how to give your agent a wallet, fund it with USDC, discover services in Agent Marketplace, and settle gasless payments through Circle Gateway. Get started at agents.circle.com.
#### **Introducing Circle Agent Stack: financial infrastructure for the agentic economy.**
As agents begin paying for APIs, data, compute, and services in real time, developers need infrastructure designed for programmable, machine-speed transactions.
**Agent Stack brings together:**
- ✅ Agent Wallets for controlled access to USDC
- ✅ Agent Marketplace for discovering agentic services
- ✅ Circle CLI for repeatable financial actions
Together with Nanopayments powered by Circle Gateway and Circle Skills, Agent Stack helps agents hold funds, discover services, and transact programmatically with USDC.
