## Overview <a href="#overview" id="overview"></a>

This tutorial guides you through integrating **RouterLink**—WORLD3's decentralized AI model routing infrastructure—with **TypingMind**, a professional AI chat interface platform.

### Purpose <a href="#purpose" id="purpose"></a>

RouterLink provides a unified API endpoint that routes requests to multiple AI model providers through a decentralized network. By integrating RouterLink with TypingMind, 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 <a href="#what-you-will-learn" id="what-you-will-learn"></a>

By completing this tutorial, you will:

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

### Prerequisites <a href="#prerequisites" id="prerequisites"></a>

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

## Introduction to TypingMind <a href="#introduction-to-typingmind" id="introduction-to-typingmind"></a>

<figure><img src="/files/IHtRDR3tB6a4UwA10yZ6" alt=""><figcaption></figcaption></figure>

**TypingMind** is a professional, customizable chat interface (UI) that enables users to interact with multiple large language models (LLMs) such as GPT, Claude, and Gemini from a single platform. It offers enhanced features for organizing conversations, managing prompts, uploading documents for context (RAG), and building custom AI agents.

Key features include:

* Multi-provider model support with custom API configurations
* Advanced prompt library and conversation management
* Document upload capabilities for Retrieval-Augmented Generation (RAG)
* Options for personal use, team collaboration, and self-hosting for privacy

### Step 2: Add a Custom Model <a href="#step-2-add-a-custom-model" id="step-2-add-a-custom-model"></a>

1. Click the **Models** icon in the left sidebar, then select **"Add custom model"**.

<figure><img src="/files/5YfloAGrWJ6LhqTVL48O" alt=""><figcaption></figcaption></figure>

For this tutorial, we will configure **OpenAI's GPT-5.2** model via RouterLink.

***

### Step 3: Retrieve Model Configuration from RouterLink <a href="#step-3-retrieve-model-configuration-from-routerlink" id="step-3-retrieve-model-configuration-from-routerlink"></a>

<figure><img src="/files/rwLyA5WvOD2Gev2n6YHE" alt=""><figcaption></figcaption></figure>

1. Visit the RouterLink model page at [OpenAI's GPT 5.2 model](https://world3.ai/routerlink/GPT%20-%205.2) to access the integration details.
2. In the **Integration Guide** section, locate the source code example and copy the **model** identifier.&#x20;

### Step 4: Configure Model Parameters <a href="#step-4-configure-model-parameters" id="step-4-configure-model-parameters"></a>

Enter the following configuration values in the TypingMind custom model form:

<figure><img src="/files/JdM5tvKM13MAJ6M0NnYJ" alt=""><figcaption></figcaption></figure>

#### API Configuration Parameters <a href="#api-configuration-parameters" id="api-configuration-parameters"></a>

| Parameter        | Value                                                   |
| ---------------- | ------------------------------------------------------- |
| **Model ID**     | `world3-router-north-america/openai/gpt-5.2`            |
| **API Endpoint** | `https://router-link.world3.ai/api/v1/chat/completions` |

#### Custom Headers Configuration <a href="#custom-headers-configuration" id="custom-headers-configuration"></a>

Expand the **Advanced** section to configure **Custom Headers**:

| Key               | Value                   |
| ----------------- | ----------------------- |
| **Authorization** | `Bearer <YOUR_API_KEY>` |
| **Content-Type**  | `application/json`      |

{% hint style="info" %}
&#x20;For the Authorization header, replace `<YOUR_API_KEY>` with your actual RouterLink API key. Ensure there is exactly **one space** between `Bearer` and your API key. **Example:** If your API key is `sk-1234abcd`, enter `Bearer sk-1234abcd`
{% endhint %}

If you are using the free daily WORLD3 credits, please set the max tokens to ensure the service works properly (for example, set it to 4096).

| Issue                     | Solution                                                                              |
| ------------------------- | ------------------------------------------------------------------------------------- |
| **Authentication failed** | Verify your API key is correctly formatted with `Bearer` prefix (including the space) |
| **Model not responding**  | Confirm the model ID matches the exact format from the RouterLink documentation       |
| **Connection timeout**    | Check your network connectivity and ensure the API endpoint URL is correct            |
| **Test button fails**     | Verify all custom headers are properly configured (Authorization and Content-Type)    |
