Payment rails for autonomous AI agents on Base. An ERC-8004 identity registry with on-chain reputation, plus x402 USDC micropayments gating API access through the HTTP 402 flow.

Built the full stack: Solidity contracts, TypeScript backend and frontend. The payment gateway verifies on-chain settlement before releasing the API response.
