Magic API uses API Keys to identify projects in the system. They are private, so you should not share them or publicly display them.
To generate an API Key, navigate to your project page. At the top you'll find the API Keys section where you can find the Generate button. Clicking on the button will generate a new API Key assigned to this project.
To use the Magic API, attach the API key to every request using the x-api-key header:
x-api-key: <API_KEY>
