REST APIs typically return data in various formats, including XML, making it suitable for applications that require structured data communication. This means that a Flash developer can retrieve or send XML-formatted data seamlessly using REST API calls, facilitating effective communication and data processing in applications.

Mongo is a NoSQL database that stores data in a field/value format and is not directly related to markup text like XML. A browser extension is a tool that enhances the browsing experience, typically not aimed at data communication like REST.
