## Overview

This tutorial guides you through integrating **RouterLink**—WORLD3's decentralized AI model routing infrastructure—with **ChatboxAI**, a versatile AI client application available across multiple platforms.

### Purpose

RouterLink provides a unified API endpoint that routes requests to multiple AI model providers through a decentralized network. By integrating RouterLink with ChatboxAI, you gain access to a diverse range of large language models (LLMs) without managing multiple API keys or provider-specific configurations.

### What You Will Learn

By completing this tutorial, you will:

* **Configure ChatboxAI** to connect with RouterLink's API endpoint
* **Authenticate** using your RouterLink API credentials
* **Add and manage AI models** available through the RouterLink network
* **Execute inference requests** through ChatboxAI's conversational interface

### Prerequisites

Before proceeding, ensure you have:

* A RouterLink API key (obtain one from the [Quick Start Guide](https://docs.world3.ai/world3/how-to-guides/routerlink/quick-start-guide))
* A web browser with internet access
* Basic familiarity with API configuration concepts

***

### Step 3: Retrieve Model Configuration from RouterLink

For this tutorial, we will configure **Claude Opus 4.5** model via RouterLink.

1. Visit the RouterLink model page at [Claude Opus 4.5](https://world3.ai/routerlink/Claude%20Opus%204.5) to access the integration details.
2. Select **"OpenAI"** as the integration format.
3. The following configuration details will be displayed:
