Show HN: X402 Agent Starter Kit: AI agents that pay for their own APIs
peiyaooo Wednesday, February 18, 2026
Hey HN, we built a set of production-ready AI agent templates with x402 micropayments baked in.
The problem: agents that need multiple APIs face signup/KYC/key-management overhead that doesn’t scale. x402 replaces all of that with HTTP-native payments.
Currently supporting USDC on Base, more integrations soon.
The kit includes 5 agent templates (web scraper, image gen, search, translation, code review). Clone, configure a wallet, run. 93 tests passing. Built on Coinbase Developer Platform.
This is the first project from our “1 app per week” studio experiment.

Would love feedback on the architecture and the agent templates. What x402 use cases would you want to see next?
