Getting Started

The package is available on Nuget. After installing the package the Coinbase API is available by using the CoinbaseRestClient and CoinbaseSocketClient.

Installation

Nuget

dotnet add package Jkorf.Coinbase.Net

GitHub packages

Coinbase.Net is available on GitHub packages. You'll need to add https://nuget.pkg.github.com/JKorf/index.json as a NuGet package source.

Download release

The NuGet package files are added along side the source with the latest GitHub release which can found here.

API Access

Coinbase.Net can be configured using Dotnet dependency injection, after which the clients can be injected into your services. It also correctly configures logging and HttpClient usage.

// Configure options from config file
// see https://github.com/JKorf/CryptoExchange.Net/tree/master/Examples/example-config.json for an example
builder.Services.AddCoinbase(builder.Configuration.GetSection("Coinbase"));
		  
// OR
		  
 builder.Services.AddCoinbase(options => {
  // Configure options in code
  options.ApiCredentials = new ApiCredentials("APIKEY", "APISECRET");
});

The ICoinbaseRestClient and ICoinbaseSocketClient can then be injected.

Alternatively the rest and socket client can be constructed directly

var restClient = new CoinbaseRestClient(options => {
  // Options can be configured here, for example:
  options.ApiCredentials = new ApiCredentials("KEYNAME", "PRIVATEKEY");
});
var socketClient = new CoinbaseSocketClient();

Examples

var coinbaseClient = new CoinbaseRestClient();
var result = await coinbaseClient.AdvancedTradeApi.ExchangeData.GetTradeHistoryAsync("ETHUSDT");
