This is a simple lambda function that uses an external API to get the current price of cryptocurrencies on coinmarketcap.com. The function is used with Amazon Alexa and can be paired with an Alexa skill.
My goal with this project was to create a simple and easy to use reference for the cryptocurrency market with Amazon's Alexa SDK.
I was able to accomplish my initial goal and have the application respond to user input. Towards the end of January 2018, I released the application on the Amazon Skills Store and have received great reviews so far.
Here is the link to the application on Amazon's store: Cryptocurrency Prices
User Input: "Alexa, ask coin check for the current price of Bitcoin."
Alexa Response: "Okay, the current price of Bitcoin is $11,500 USD."
User Input: "Alexa, ask coin check for the top coins."
Alexa Response: "Okay, the top five cryptocurrencies are Bitcoin, Ethereum, Ripple, Bitcoin Cash, and Litecoin."
In the future, I hope to support different world currencies such as the Canadian dollar, the Euro, etc. Additionally in the future I plan on supporting more information about the cryptocurrencies such as 24h price change, etc.
