MongoDB Atlas is the global cloud database service provided by MongoDB for hosting and managing your MongoDB databases. It offers a fully-managed platform that is designed to provide easy-to-deploy, secure, and scalable MongoDB deployments in a matter of minutes. The MongoDB Atlas Data API provides an HTTP-based interface to interact with your MongoDB databases hosted on Atlas. Instead of traditional drivers or the MongoDB shell, you can use standard HTTP methods (GET, POST, PUT, DELETE) to perform CRUD (Create, Read, Update, Delete) operations on your data.
