How to Get Your OpenRouter API Key

AIWU now supports OpenRouter API, giving you unified access to over 200 AI models through a single API key and billing account.

What is OpenRouter?

OpenRouter is a unified gateway that provides access to AI models from multiple providers including OpenAI, Anthropic, Google, Meta, and dozens of others. Instead of managing separate API keys and accounts for each provider, you get one key that works with all of them.

Why Use OpenRouter with AIWU?

Simplified Management: One API key instead of juggling multiple keys from different providers.

Cost Efficiency: Pay-as-you-go pricing with competitive rates. Compare models and choose the best price-to-performance ratio for your needs.

Model Flexibility: Switch between models instantly without changing your setup. Try Claude 3.5 Sonnet, GPT-4, Gemini Pro, or open-source models like Llama 3 – all through the same integration.

Reliability: If one provider has downtime, easily fallback to another model without reconfiguring AIWU.

Access to Latest Models: Get immediate access to new models as they’re released, without waiting for AIWU updates.

Getting Started with OpenRouter

Step 1: Create Your Account

Visit openrouter.ai and sign up for a free account. You’ll need to verify your email address to proceed.

Step 2: Generate Your API Key

Once logged in:

1. Navigate to Settings in the top menu
2. Click on Keys in the sidebar
3. Click the Create Key button
4. (Optional) Give your key a descriptive name like “AIWU WordPress”
5. Copy your API key immediately – you won’t be able to see it again

Important: Store your API key securely. Treat it like a password – never share it publicly or commit it to version control.

Step 3: Add Credits to Your Account

OpenRouter uses a prepaid credit system:

1. Go to Settings → Credits
2. Click Add Credits
3. Choose your amount (minimum $5 recommended to start)
4. Complete payment through your preferred method

Your credits will be used based on the models you choose and how much you use them. Different models have different pricing – premium models like GPT-4 cost more per token than open-source alternatives.

Step 4: Connect OpenRouter to AIWU

Now you’re ready to use OpenRouter with AIWU:

1. Open your WordPress admin panel
2. Go to AIWU Settings → API Keys
3. Find the OpenRouter section
4. Paste your API key
5. Save your settings

That’s it! You can now select any OpenRouter model in AIWU’s chatbot, workflow builder, or content generation tools.
