# Agent stack

> Empower your AI agents to autonomously operate wallets, transact onchain, and pay for API services through Circle's agent-native tooling.

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](https://claude.com/claude-code), [Cursor](https://cursor.com/),
[Codex](https://openai.com/codex), [OpenClaw](https://openclaw.ai/), or any
custom AI agent.

## What you can do

* **Build with an agent-native interface**: Use
  [Circle CLI](/agent-stack/circle-cli) and [Circle Skills](/ai/skills) to give
  your agent access to [Circle Wallets](/wallets), [CCTP](/cctp), and
  [Gateway](/gateway) from a single command interface.
* **Give your AI agent wallets**: Use
  [Agent wallets](/agent-stack/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](https://agents.circle.com/services) and pay per
  request, without subscriptions or API keys.
* **Operate onchain across blockchains**: Trade tokens, bridge USDC, and execute
  onchain strategies across
  [supported blockchains](/agent-stack/agent-wallets/supported-blockchains).
