Known Issues

Sandbox results are kind of different than the live ones. Tests that pass when the sandbox is true, don't pass on live mode and causes serialization issues. The endpoints are tested on sandbox results. Not all endpoints are available for free tier. Unless coinmarketcap provides me a enterprise key I won't be able to make sure everything is on point. Please create an issue if you encounter a problem. On top of that API Docs Response Schema is not always same with the response we get. I will be sticking with the response schema for now.

Usage

To use CoinMarketCapDotNet, follow these steps:

1. Instantiate the CoinMarketCapAPI class with your API key:

string apiKey = "YOUR_API_KEY";
CoinMarketCapAPI api = new CoinMarketCapAPI(apiKey);

To use sandbox mode:
string apiKey = "YOUR_API_KEY";
CoinMarketCapAPI api = new CoinMarketCapAPI(apiKey,true);

Access the available endpoints through the instantiated API object:

Extensions to make life easier: Enum Extensions:

.GetEnumMemberValue(): Example:

CurrencyEnum currency = CurrencyEnum.EUR;
string enumMemberValue = currency.GetEnumMemberValue(); // Should return "USD" you can use this to fetch USD from endpoints.

.GetId(): Example:

CurrencyEnum currency = CurrencyEnum.USD;
int id = currency.GetId(); // You should get the cmc equivalent of EUR id.

.GetSymbol(): Example:

CurrencyEnum currency = CurrencyEnum.TRY; // You should get "TRY"
string symbol = currency.GetSymbol();

.GetCurrencyIds(): Example:

string symbols = "USD,EUR,TRY";
List<int> ids = symbols.GetCurrencyIds(); // Returns the symbol strings as a id list to be used in endpoints.

.GetAllIds(): Example:

List<int> allIds = EnumExtensions.GetAllIds<CategoryEnum>(); // Will return all the ids of a given enum

.GetAllSymbols(): Example:

List<string> enumMemberValues = EnumExtensions.GetAllSymbols<CurrencyEnum>(); // Will return all the symbols of a given enum
