Circle Agent Stack helps reduce those barriers

| AI agents can write code, browse the web, and automate complex workflows. But when they need to pay for an API or premium service, autonomous workflows break down. They stop and wait for a human to sign up, enter a payment card, and approve the transaction. |
| Circle Agent Stack helps reduce those barriers. |
| Built on USDC, Circle Agent Stack gives agents the infrastructure they need to hold funds, discover services, and pay autonomously. |
| With Agent Wallets, developers define spending limits while agents transact independently. Agent Marketplace lets agents discover and pay for services in real time, without checkout flows or API keys. Nanopayments powered by Circle Gateway make transactions as small as $0.000001 practical, enabling pay-per-call and pay-per-token pricing. |
| Agents are evolving from assistants into economic actors. Purpose-built infrastructure lets them transact without breaking autonomous workflows, so they can keep working. |
