CoinMarketCap API interface (cmc-info)

Simple API interface for CoinMarketCap's pro API. Requests are asynchronous and use promises. For simpler implementation, the request-promise module is used.

Installation & use

npm i cmc-info

How to use in your code: see example.

For getting multiple values at the same time, use options none or 'quote', this way you only need 1 API call for all values. For getting single values, you can use my pre-made function options. See usage below.

API key

You can register and get a free API key here. There are also paid options for more advanced and commercial use. Set your key in cmc-api.js.
