Infrastructure for AI agent finance, open to everyone. Use it, fork it, build on top of it.
Payment infrastructure for AI agents. Agents get their own wallets, spend within policies you define, and pay automatically using the x402 protocol — no human in the loop. Policy-enforced spending, USDC settlement on Base, and full audit trail. x402-compatible out of the box.
Free developer environment for building and testing AI agent payments. Runs on Base Sepolia with testnet USDC. Includes a mock x402-compatible API server and three runnable scripts: basic payment flow, full 402 challenge/response cycle, and policy enforcement. No credit card. No real money.
