The text is a tutorial on how to build an application using Python, AWS Lambda, Twilio Lookup and SMS to identify unknown phone numbers. The app will receive a text message with a phone number, parse the number, look up the caller name using the Twilio Lookup API, and send a response back to the original sender with either the caller's name or an error message if no name is found. The tutorial covers setting up AWS Lambda, Amazon API Gateway, and Twilio, as well as writing the necessary Python code for the app.
