The first facilitator-agnostic middleware for x402. Open-source infrastructure for the autonomous AI economy.
Status: Pre-alpha. v0.1.3 live on npm.
Interouter sits between Next.js SSR runtimes, blockchain networks, and AI inference systems. A single deterministic API that orchestrates 402 Payment Required (x402 standard) flows while handling runtime compatibility across diverging facilitator implementations (Coinbase CDP, foundation reference, self-hosted).
It is the runtime layer that makes the x402 standard actually work in production.
Built on the x402 standard — under the Linux Foundation, supported by Coinbase, Google, AWS, Stripe, Visa, and Cloudflare.
This is a TypeScript monorepo.
