Circle Agent Stack lets your AI agent hold and transact USDC and other tokens across blockchains, discover and pay for x402 services, and operate within built-in compliance guardrails. Use with Claude Code, Cursor, Codex, OpenClaw, or any custom AI agent.

What you can do

  • Build with an agent-native interface: Use Circle CLI and Circle Skills to give your agent access to Circle Wallets, CCTP, and Gateway from a single command interface.
  • Give your AI agent wallets: Use Agent Wallets to hold and spend USDC and other tokens with customizable spending controls and built-in compliance guardrails.
  • Discover and pay for services on demand: Search x402-compatible APIs and pay per request, without subscriptions or API keys.
  • Operate onchain across blockchains: Trade tokens, bridge USDC, and execute onchain strategies across supported blockchains.
