# Quick Start Guide

## Overview

[**RouterLink**](https://world3.ai/new-agent/router-link) **is a one-stop large-scale model access network provided by WORLD3.** 

Developers only need one API key to call all mainstream AI models through a unified WORLD3 endpoint, including:

* OpenAI Channel (GPT series)
* Anthropic Channel (Claude series)
* GCP Vertex (Gemini series)
* World3 Router Asia Pacific
* World3 Router North America
* And more models to be integrated later.

RouterLink automatically implements:

* Unified Interface Format
* Automatic routing to the target provider
* Multi-model invocation and transparent billing
* Token-level Credits Tracking
* Secure API Key Management

**On the client side, your application only needs to communicate with RouterLink, instead of managing integrations with multiple vendor APIs.**

## API Key Management

### 1. Generate API Key

**Step1:** Go to the New WORLD3 → RouterLink page.

**Step2: Click "Generate API Key" or the "Generate" link** below to generate an API Key.

**Step3:** After clicking, the following pop-up window will appear. When the API key is revealed, it is displayed only once, so please copy it immediately and store it securely. If the key is lost, it must be regenerated, so careful handling and management are strongly recommended.

**Step4:** You can view detailed API Key information in the table below.

### 2. Regenerate and Delete API Key

This system stores only one active API key. When an API key is regenerated or deleted, the previous key is permanently invalidated and cannot be recovered. Please proceed with caution.

**Step1:** **Click the "Regenerate API Key" button** on the page to regenerate the API Key, or **click the "Delete" button** below to delete the API Key.

**Step2: Click the "Confirm" button** to **regenerate or delete** the operation. If you need to generate it again later, simply execute Steps 1-3 in the **Generate API Key** process.

1. This section will introduce how to integrate RouterLink into different development environments.
2. RouterLink provides a unified API gateway that enables developers to access and switch between multiple Large Language Models (LLMs) using a single API key. It supports **both OpenAI-compatible APIs and native provider APIs** (such as Anthropic Messages API), offering flexible integration options for different use cases.
   1. **OpenAI-compatible API** is recommended for editors, plugins, and chat clients.
   2. **Native provider APIs** are available for advanced usage and full feature access.
3. The examples below demonstrate several common integration scenarios.
4. For more details, please see [the Integration Guide.](https://docs.world3.ai/world3/how-to-guides/routerlink/tutorials)
