Did you know that the most basic coinmarketcap api functionality can be accessed using R Programming? There's a package for that on github : CoinmarketcapR. This is a community package. We are not sure how safe, secure and how it can be best used. An initial looks shows that : this library is somewhat popular, has youtube tutorials (unofficial), can access some basic coinmarketcap APIs, while most APIs are deprecated.
