Building With x402 Agents, Paid APIs, & Embedded Wallets
summary
Four $5,000 prizes reward projects using Coinbase Developer Platform tools and the session shows exactly how to wire them together: embedded wallet under the hood for user sign‑in, a server wallet for agent custody, and X42 to replace API keys so agents can pay APIs onchain. A live demo charges 1 cent USDC on Base, settles via a facilitator in under a second, and starter code is on GitHub so teams can fork a working scaffold and ship fast.
