There is no “free account” for API. The use of the service costs money by the amount of data used. There is only possibility of a free trial credit, which expires three months after you first created your OpenAI account. Now you'll need to purchase a credit balance in order to make calls.

OpenAI provides some mechanisms for limiting API key permissions, such as restricting access to specific IP addresses or setting usage limits. These settings can help you control how and where your API key is used, adding an extra layer of security to prevent misuse.

AI is crucial in enhancing Google Maps by analyzing vast amounts of data to provide users with accurate and relevant information. By leveraging AI technology, Google Maps can predict traffic patterns, suggest alternate routes, and even provide personalized recommendations based on user preferences.

AI-driven navigation apps continuously collect data from various sources, including GPS signals, smartphones, and traffic sensors. This data is processed in real-time by sophisticated AI algorithms to create accurate traffic flow maps.
