Circle Introduces Agent Stack for USDC-Powered API Payments
Circle has launched Agent Stack, a tool that enables API providers to accept USDC payments from autonomous software agents.
The innovation allows for new revenue streams through pay-per-use pricing, aiming to transform how APIs monetize their services.
Agent Stack combines instant USDC payments with tools like x402, making it easy for API providers to turn their endpoints into agent-ready services.
The Agent Marketplace is already live, featuring agent-friendly APIs across three core categories: data and intelligence, digital infrastructure, and real-world execution.
