Kotlin microservice to calculate the value of your cryptocurrency portfolio
Run the CryptoEvalServer.kt file to start up the server.
To invoke it, simply open the browser (or use an HTTP client) pointing to http://localhost:9000 and adding the crypto portfolio in query string (using the crypto symbol as key and quantity as value). F.i. assuming you want to calculate the value of a portfolio of 2.12 BTC and 12.1 ETH, simply point to
http://localhost:9000?btc=2.12ð=12.1
The result of the invocation is a response containing only the value of the portfolio in USD.
