Building a RESTful API with Rails

Rails is a popular choice for building RESTful APIs, and this tutorial demonstrates how to create a simple REST API using Rails to retrieve a randomly generated credit score. The process involves setting up prerequisites such as Ruby, Rails, an IDE, and Postman for testing. The tutorial guides users through generating a Rails API project, configuring CORS for traffic, creating a GET endpoint for retrieving the credit score, and writing the controller function that returns a JSON payload with a random number between 500 and 900. The API can be run locally by starting the Rails server, and users can test the endpoint using Postman. The tutorial also suggests further steps for expanding the API, such as integrating security measures, using API gateways, and exploring API analytics and monetization through platforms like Moesif.
