API for the MyCryptoGraph project
MVP: /get-total-balances/
Use Poloniex API for that:
* public API request - returnTicker (https://poloniex.com/public?command=returnTicker, check USD_BTC)
* private API reqest - returnCompleteBalances
Need to add: * Replace CURL requests with Requests library * Add better error handling * Add response caching
API: PHP (Slim 3.1, rmccue/Requests 1.7.0)
