Step-by-Step Guide to Set Up and Use OpenRouter AI

Step 1: Create an Account

• Visit OpenRouter.ai and sign up for an account.
• Verify your email and log in to the dashboard.

Step 2: Obtain an API Key

• Navigate to the API Keys section in your dashboard.
• Click "Create New Key" and enter a descriptive name.
• Generate the key and store it securely.

Step 3: Install Dependencies

For JavaScript/TypeScript projects, install the OpenRouter SDK:

bash

npm install @openrouter/ai-sdk-provider
        

For Python projects, install the OpenAI package:

bash

pip install openai
        

Step 4: Configure Your Environment

Create a .env file to store your API key:

javascript

OPENROUTER_API_KEY=your_api_key_here
        

Update your configuration files to use the OpenRouter API endpoint:

javascript

const openrouter = createOpenRouter({ apiKey: process.env.OPENROUTER_API_KEY });
        

Step 5: Make API Calls

Use the OpenRouter API to interact with models:

javascript

const response = await fetch('https://openrouter.ai/api/v1/chat/completions', {
  method: 'POST',
  headers: {
    'Authorization': `Bearer ${process.env.OPENROUTER_API_KEY}`,
    'HTTP-Referer': 'https://your-site.com',
  },
  body: JSON.stringify({
    model: 'anthropic/claude-2',
    messages: [{ role: 'user', content: 'Hello!' }],
  }),
});
        

Real-World Use Cases

1. AI-Powered Writing Assistant: Build a tool that generates, edits, and adapts content using multiple AI models. For example, use GPT-4 for creative writing and Claude for technical editing.
2. Multi-Model Chatbots: Create chatbots that switch between models based on context or user preferences. For instance, use Claude for casual conversations and GPT-4 for complex queries.
3. AI Model Comparison: Compare the performance of different models for specific tasks, such as evaluating GPT-4 and Claude on summarization tasks.
4. Customized AI Applications: Develop specialized applications for fields like finance, law, or medicine. For example, use PaLM for legal document analysis and GPT-4 for financial forecasting.
