x402 Facilitator Docs
Welcome to the documentation for the Raid Guild x402 Facilitator and its Next.js integration. This site explains how the facilitator works, how to deploy it, and how to integrate it into a client app with a clean, production-safe flow.
If you are brand new to x402, start with the Overview and Quick Start. If you are integrating into an app, jump to Next.js Integration and API Reference.
What this project is
The x402 Facilitator is a hosted service that verifies and settles on-chain payments using the x402 protocol. It sits between your backend and the chain, handling signature checks, balances, and settlement transactions so your app can focus on business logic.
