Let your AI agents pay their own way.Safely.

WORK
An agent wallet that can’t overspend
Live demo · test network
An AI agent pays for API calls on its own through x402. Its wallet is a smart contract: any payment that breaks a rule is refused before money moves, and it pays services outside its list only if they have a good ERC-8004 reputation from reviewers I trust. Running live on the Base Sepolia test network.
- Spending limits enforced in the contract: per payment, per day and per task
- Every payment, refusal and rating is a public on-chain record anyone can verify
- Impostors and unknown services are refused; trust is earned through on-chain reputation
