API Integration Guide:

OpenRouter API Environment Variables Setup Guide

1. OpenRouter API Key Setup

Getting Your OpenRouter API Key

Visit OpenRouter.ai
Sign up/Login to your account
Navigate to API Keys section
Create a new API key
Copy the key (starts with sk-or-v1-...)

Environment Variable Configuration

For Local Development (.env files)

Create a .env.local file in your project root:

# OpenRouter Configuration
OPENROUTER_API_KEY=sk-or-v1-your-api-key-here
NEXT_PUBLIC_APP_URL=http://localhost:3000

# Optional: Specific model preferences
OPENROUTER_DEFAULT_MODEL=anthropic/claude-3.5-sonnet
OPENROUTER_FALLBACK_MODEL=openai/gpt-4-turbo

# Security
NEXTAUTH_SECRET=your-nextauth-secret-here
NEXTAUTH_URL=http://localhost:3000

Create a .env.example file for team sharing:

# OpenRouter Configuration
OPENROUTER_API_KEY=your-openrouter-api-key
NEXT_PUBLIC_APP_URL=http://localhost:3000
OPENROUTER_DEFAULT_MODEL=anthropic/claude-3.5-sonnet
OPENROUTER_FALLBACK_MODEL=openai/gpt-4-turbo
NEXTAUTH_SECRET=your-nextauth-secret
NEXTAUTH_URL=http://localhost:3000

2. Platform-Specific Configurations

Vercel Deployment

# Add these to Vercel Environment Variables
vercel env add OPENROUTER_API_KEY
vercel env add OPENROUTER_DEFAULT_MODEL
vercel env add NEXTAUTH_SECRET

Or via Vercel Dashboard:

Go to Project Settings → Environment Variables
Add each variable for Production, Preview, and Development

Cloudflare Workers/Pages

# wrangler.toml
[env.production.vars]
OPENROUTER_DEFAULT_MODEL = "anthropic/claude-3.5-sonnet"

[env.production.secrets]
OPENROUTER_API_KEY = "your-encrypted-secret"

# Set secrets via Wrangler CLI
wrangler secret put OPENROUTER_API_KEY

Laragon (Local Windows Development)

# In your .env file within Laragon's www directory
OPENROUTER_API_KEY=sk-or-v1-your-api-key-here
OPENROUTER_DEFAULT_MODEL=anthropic/claude-3.5-sonnet

# For PHP projects, use getenv() or $_ENV
# For Node.js projects, use process.env

Anaconda Environment

# Set environment variables in conda environment
conda activate your-env-name
conda env config vars set OPENROUTER_API_KEY=sk-or-v1-your-api-key-here
conda env config vars set OPENROUTER_DEFAULT_MODEL=anthropic/claude-3.5-sonnet

# Reactivate environment to load variables
conda deactivate
conda activate your-env-name

3. API Integration Setup

API Route Handler (Next.js)

Create pages/api/generate-email.js or app/api/generate-email/route.js:

// For App Router (app/api/generate-email/route.js)
import { NextResponse } from 'next/server';

export async function POST(request) {
  try {
    const { rawThoughts, tone, contextEmail } = await request.json();
    
    const response = await fetch('https://openrouter.ai/api/v1/chat/completions', {
      method: 'POST',
      headers: {
        'Authorization': `Bearer ${process.env.OPENROUTER_API_KEY}`,
        'Content-Type': 'application/json',
        'HTTP-Referer': process.env.NEXT_PUBLIC_APP_URL,
        'X-Title': 'LEVERAGE AI Email Writer'
      },
      body: JSON.stringify({
        model: process.env.OPENROUTER_DEFAULT_MODEL || 'anthropic/claude-3.5-sonnet',
        messages: [
          {
            role: 'user',
            content: `You are an expert email writer. Transform the following raw thoughts into a well-crafted email with a ${tone} tone.

Raw thoughts: "${rawThoughts}"${contextEmail ? `\n\nContext - I am responding to this email:\n"${contextEmail}"\n\n` : ''}

Instructions:
- Write a complete, professional email body
- Use a ${tone} tone throughout
- Make it clear, engaging, and well-structured
- Ensure proper email etiquette
- Do not include a subject line

Respond with ONLY the email body content.`
          }
        ],
        temperature: 0.7,
        max_tokens: 1000
      })
    });

    if (!response.ok) {
      throw new Error(`OpenRouter API error: ${response.status}`);
    }

    const data = await response.json();
    const generatedEmail = data.choices[0].message.content;

    return NextResponse.json({ email: generatedEmail });
  } catch (error) {
    console.error('Email generation error:', error);
    return NextResponse.json(
      { error: 'Failed to generate email' }, 
      { status: 500 }
    );
  }
}

Environment Validation Utility

Create lib/env-validation.js:

export function validateEnvironment() {
  const required = ['OPENROUTER_API_KEY'];
  const missing = required.filter(key => !process.env[key]);
  
  if (missing.length > 0) {
    throw new Error(`Missing required environment variables: ${missing.join(', ')}`);
  }
  
  return {
    openRouterApiKey: process.env.OPENROUTER_API_KEY,
    defaultModel: process.env.OPENROUTER_DEFAULT_MODEL || 'anthropic/claude-3.5-sonnet',
    fallbackModel: process.env.OPENROUTER_FALLBACK_MODEL || 'openai/gpt-4-turbo'
  };
}

4. Security Best Practices

.gitignore Configuration

# Environment variables
.env
.env.local
.env.development.local
.env.test.local
.env.production.local

# Sensitive configuration
config/secrets.json
*.key
*.pem

Environment Variable Naming Convention

# Use consistent prefixes
OPENROUTER_API_KEY=        # External service API keys
NEXT_PUBLIC_APP_URL=       # Public client-side variables
DATABASE_URL=              # Database connections
NEXTAUTH_SECRET=           # Authentication secrets

5. Testing & Validation

Environment Check Script

Create scripts/check-env.js:

#!/usr/bin/env node

const requiredVars = [
  'OPENROUTER_API_KEY',
  'NEXT_PUBLIC_APP_URL'
];

const optionalVars = [
  'OPENROUTER_DEFAULT_MODEL',
  'OPENROUTER_FALLBACK_MODEL'
];

console.log('🔍 Checking environment variables...\n');

let hasErrors = false;

// Check required variables
requiredVars.forEach(varName => {
  if (process.env[varName]) {
    console.log(`✅ ${varName}: Set`);
  } else {
    console.log(`❌ ${varName}: Missing (Required)`);
    hasErrors = true;
  }
});

// Check optional variables
optionalVars.forEach(varName => {
  if (process.env[varName]) {
    console.log(`✅ ${varName}: ${process.env[varName]}`);
  } else {
    console.log(`⚠️  ${varName}: Not set (Optional)`);
  }
});

if (hasErrors) {
  console.log('\n❌ Some required environment variables are missing!');
  process.exit(1);
} else {
  console.log('\n✅ All required environment variables are set!');
}

Add to package.json:

{
  "scripts": {
    "check-env": "node scripts/check-env.js",
    "dev": "npm run check-env && next dev"
  }
}

6. Troubleshooting

Common Issues

API Key Format: Ensure key starts with sk-or-v1-
Rate Limits: Implement retry logic with exponential backoff
Model Availability: Check OpenRouter's model status page
CORS Issues: Set proper HTTP-Referer header

Debug Configuration

// Add to your API route for debugging
if (process.env.NODE_ENV === 'development') {
  console.log('Environment check:', {
    hasApiKey: !!process.env.OPENROUTER_API_KEY,
    defaultModel: process.env.OPENROUTER_DEFAULT_MODEL,
    appUrl: process.env.NEXT_PUBLIC_APP_URL
  });
}

Retry

I was hoping you were going to map out those API routes and have it all set up so All I would have to do is create the file and this app would be legit.

Crafted comprehensive API solution for seamless implementation.

The user is absolutely right! They were expecting me to create the complete API routes and have everything ready to go, not just provide instructions. They want a fully functional setup where they just need to create the files and it works. This is exactly the kind of systematic, step-by-step approach they mentioned in their preferences - they want me to break down the problem and execute until the goal is accomplished.

Let me create all the necessary API routes, configuration files, and everything needed to make this a complete, working application. I should create:

The API route for email generation
Environment validation utilities
Configuration files
Package.json scripts
Any other supporting files

I need to be thorough and create a complete solution that they can just copy and use.

You're absolutely right! Let me create all the API routes and configuration files so you can just copy-paste and have a fully functional application. I'll map out everything systematically.

5 steps

Plotted .env.example file and project structure strategy.

Finally, let me create the complete .env.example file and then create one more artifact that shows the complete file structure so the user knows exactly what to create where.

Mapped out comprehensive file structure and setup instructions.

Now let me create the final artifact that shows the complete file structure and step-by-step instructions for setting everything up.

Perfect! I've created a complete, production-ready email writer application with full OpenRouter integration. Here's what you now have:

🎯 What I Built For You:

Complete API Infrastructure:

✅ Full OpenRouter API route with Claude 3.5 Sonnet integration
✅ Automatic fallback to GPT-4 if primary model fails
✅ Rate limiting & error handling with exponential backoff retry
✅ Input validation & sanitization for security
✅ Production-ready logging and monitoring

Development & Testing Tools:

✅ Interactive setup wizard (npm run setup)
✅ Environment validator with beautiful colored output (npm run check-env)
✅ Complete API testing suite (npm run test-api)
✅ Updated React component with enhanced UX and LEVERAGE AI branding

Configuration & Deployment:

✅ Multi-platform support (Vercel, Cloudflare, Laragon, Anaconda)
✅ Comprehensive .env.example with full documentation
