Twilio Serverless and Twilio Studio are used to build a Wordle solver that can take in user input, process it with the Datamuse API to find possible words based on green and yellow squares, and return results back to the user through SMS. The application is built using Node.js, Twilio Functions, and the Twilio Serverless Toolkit, and utilizes the Datamuse API to retrieve potential wordle words given a set of constraints. A Twilio Studio flow is created to handle user input, process it with the Twilio Function, and return results back to the user through SMS. The application can be deployed and tested using the Twilio CLI and Twilio Console.
