x402 Starter Kit lets you generate fully configured x402 APIs in minutes. You pick one of three facilitator options—Coinbase, a local node, or your own custom setup—and the kit handles the setup details. It includes a client-side testing service so you can validate your endpoints without writing extra test code. Everything runs in Docker, making deployment on EigenCompute a one-step process. The starter kit is open source on GitHub, so you can fork it, tweak the prompt that defines your API, and submit pull requests. In practice, you type one prompt and the kit scaffolds routes, middleware, and docs. It’s aimed at “vibe coders” who want rapid prototyping without boilerplate headaches.
