Infrastructure for AI agent finance, open to everyone. Use it, fork it, build on top of it.
On-chain payment infrastructure. 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.
