An API key is a simple encrypted string that you can use when calling Google Cloud APIs. A typical use of an API key is to pass the key into a REST API call as a query parameter.
API keys are useful for accessing public data anonymously, and are used to associate API requests with the consumer Google Cloud project for quota and billing.
API Keys provides you a programmatic interface to create and manage API keys for your project. It provides you more control over API keys than the API key-related tasks that you can do in the Cloud Console.
