Barchart OnDemand Market Data API Client

Barchart offers free Market data API on barchart.com/ondemand/free-market-data-api, to use the API you need an API key which is provided singing up on theirs website.

Barchart also offers a larger catalog of paid for APIs which you need an API key for that has been granted such access. This library currently only supports the free APIs, but I plan to eventually add support for some more of the paid ones as well.

This client offers access to free methods getQuote and getHistory.

This repo was forked from yagop/barchart-market-data-api and updated to es6
