Why You Need an API Key

An API (Application Programming Interface) key is your unique identifier for communicating with Google Gemini models. It allows you to use its powerful AI capabilities in CLI tools, your own programs, or any service that supports Gemini. Simply put, it's your personal key to the world of AI.

Step 2: Create a New API Key

Once logged in, you will be taken to the API key management console.

1. Click the button that says "Create API key in new project".
2. The system will instantly generate a new API key for you.

Step 3: Copy and Secure Your Key

You now have your API key!
