x402 tools, templates and services

x402 lets an AI agent pay for an API call with a stablecoin over plain HTTP, with no account or API key. Everything here comes from the team that runs eight paid x402 routes in production on api.youraitools.co.

Pick by how much you want to do yourself: the Builder Skills teach your coding agent the full paywall, audit, settlement and listing workflow; the Proxy Template is a Cloudflare Worker you put in front of an existing API; the Setup Service is us doing it for you. Not sure your endpoint works yet? Run the free checker first.

FAQ

Which one should I start with?
If you write code with an agent, start with x402 Builder Skills ($29). If you already have an API and want a paywall in front of it today, use the x402 Proxy Template ($19). If you want it done for you, book the x402 Setup Service.
Do I need a crypto wallet?
You need a wallet address that receives USDC (your payTo address). None of these products ask for your private keys.
Can I check my endpoint for free?
Yes. The free checker at /verify-endpoint sends one unpaid request and reports what your 402 response gets right and wrong.
