# Introduction

Welcome to the Neura API documentation. These pages describe how to authenticate with the Coinbase X402 facilitator, configure your environment, and integrate every route that Neura exposes. Each chapter expands on concepts introduced in the [Coinbase X402 welcome guide](https://docs.cdp.coinbase.com/x402/welcome) and applies them directly to Neura's paid data surfaces.
