Claude Code + OpenRouter: The Setup Guide That Actually Explains Things

Introduction

The rise of AI language models like Claude Code has led to numerous discussions among developers about integrating these tools into their workflows. One such integration is the combination of Claude Code with OpenRouter, a router configuration tool. This article aims to provide a comprehensive setup guide that not only walks you through setting up these tools but also explains each step in detail, making it easier for beginners to understand and use them effectively.

Setting Up Claude Code

Installing Claude Code

To get started, download the Claude Code app from its official website or repository. Ensure you have Node.js installed on your system as Claude Code is a JavaScript-based application. Follow these steps to install:

bash

npm install -g @claude.ai/cli

After installation, verify that Claude Code was set up correctly by running:

bash

claude version

Ensure the output shows the correct version of Claude Code.

Configuring API Access

Once Claude Code is installed, you need to configure it to access your OpenRouter setup. First, generate an API token from your OpenRouter account settings or using the command line tool. Here’s how:

bash

# Generate an API token for CLI configuration
openrouter api tokens create --name custom-token

# Retrieve the generated token
TOKEN=$(openrouter api tokens show --name custom-token | grep -Po '(?<="token":")[^"]*')

In Claude Code, set up your API credentials by navigating to its settings and entering these details.

Setting Up OpenRouter Integration with Claude Code

Configuring OpenRouter Access in Claude

To integrate OpenRouter with Claude Code, you will need to create a custom configuration. This involves creating an instance of the @claude.ai/openrouter plugin within your project’s setup file. Here is how it can be done:

typescript

import { createClient } from '@claude.ai/openrouter';

const openRouterClient = createClient({
  apiToken: process.env.OPENROUTER_API_TOKEN,
});

export default openRouterClient;

Replace process.env.OPENROUTER_API_TOKEN with the actual API token you have configured earlier. This allows Claude Code to access and interact with your OpenRouter setup seamlessly.

Testing Your Integration

After setting up both components, it’s essential to test their integration to ensure everything works as expected. You can do this by creating a simple router configuration via the CLI or through Claude Code itself:

bash

# Example of configuring a route using OpenRouter's API
openrouter routes create --name testRoute --dest 80

# Alternatively, setting up in Claude:
// Assuming you have created a `openRouterClient` instance earlier.
await openRouterClient.routes.create({
  name: 'testRoute',
  destination: {
    port: 80,
  },
});

console.log('Route configured successfully');

Additional Considerations

While the setup process is straightforward, there are additional considerations for optimal performance and security:

Security: Ensure that your API tokens used for integration are kept secure.

Performance: For large-scale setups or high-throughput operations, consider scaling configurations dynamically using OpenRouter’s features.

By following these steps and ensuring each component integrates correctly, you can leverage Claude Code alongside OpenRouter to streamline network management tasks significantly.
