OpenRouter Setup

Get your OpenRouter API key to power N8N Insider's AI features.

What is OpenRouter?

OpenRouter is a unified API that gives you access to multiple AI models from various providers (OpenAI, Anthropic, Google, and more) through a single API key. N8N Insider uses OpenRouter to power its AI features.

Step 1: Create an OpenRouter Account

  1. Go to openrouter.ai
  2. Click "Sign In" or "Sign Up"
  3. Create an account using Google, GitHub, or email

Step 2: Add Credits (Optional for Free Tier)

OpenRouter offers some free models, but for the best experience with models like GPT-4 or Claude, you'll need to add credits:

  1. Go to your OpenRouter dashboard
  2. Click "Credits" in the sidebar
  3. Add credits via credit card or crypto

Tip: Start with $5-10 to test. Most AI requests cost fractions of a cent.

Step 3: Generate an API Key

  1. In your OpenRouter dashboard, click "Keys" in the sidebar
  2. Click "Create Key"
  3. Give your key a name (e.g., "N8N Insider")
  4. Copy the generated API key immediately - you won't see it again!

Important!

Copy your API key and store it securely. OpenRouter only shows the full key once. If you lose it, you'll need to create a new one.

Step 4: Add Key to N8N Insider

  1. Click the N8N Insider icon in your Chrome toolbar
  2. Open Settings (gear icon)
  3. Find the "OpenRouter API Key" field
  4. Paste your API key
  5. Click "Save" or "Test Connection"

Connected!

If you see a success message, your API key is working. You can now use N8N Insider's AI features.

Choosing AI Models

N8N Insider supports multiple AI models through OpenRouter. Here are our recommendations:

Claude 3.5 Sonnet (Recommended)

Best overall for code understanding and workflow help. Great balance of speed and quality.

GPT-4o

Excellent for complex reasoning and detailed explanations.

Claude 3 Haiku

Fastest and cheapest. Good for quick questions and simple tasks.

Troubleshooting

"Invalid API Key" error

Make sure you copied the entire key including the "sk-or-" prefix.

"Insufficient credits" error

Add more credits to your OpenRouter account or try a free model.

"Rate limited" error

Wait a moment and try again. You may be making too many requests too quickly.
