This app gets 3 random facts from an animal facts API. They aren't always good facts, since they can be user submitted, but this link is the documentation for the free API:
https://alexwohlbruck.github.io/cat-facts/docs/
First, check out Models/AnimalFact.cs to see the model that represents the JSON response from an API
Then, check out AnimalFactsService to see how to use HttpClient to send a request, receive a response, and turn the JSON into a C# object
