Chapter 5. Making Alexa Talk About CryptoCurrencies

"The future is here. It's just not widely distributed yet."

– William Gibson

We designed a trivia game, called Factly, with Alexa in the last chapter. In this chapter, as promised, we are going to work on something that, at the time of writing this book, has taken the whole world by storm and, as you may have guessed from the chapter's title, it is cryptocurrencies.

In this chapter, we will be building a Skill called CryptoOracle (yes, we do understand it is a bad naming choice both in terms of syntax, semantics, and Alexa Skill-naming rules, but since we are not going to publish it yet, we are going to stick with this name) that can make Alexa talk about the latest prices of various cryptocurrencies. We will cover the following topics in this chapter:

  • A Brief Introduction to Cryptocurrencies
  • Designing the CryptoOracle skill
  • Building the CryptoOracle skill

Let's begin.
