Building a RESTful API with Go

Go is a preferred language for building RESTful APIs due to its lightweight nature, extensive libraries, and ease of execution. In a tutorial, a simple REST API is developed using Go, which allows users to retrieve a randomly generated credit score. The process involves setting up a Go environment, using an IDE for coding, and testing the endpoint with Postman. The API runs on port 8080 and returns a JSON object with the credit score when accessed. The code is designed to be expanded upon, with suggestions for future enhancements such as securing the API, integrating with an API gateway, and monetizing it. Moesif is mentioned as a tool for API analytics and monetization, offering features for deep observability and business growth.
