CoinW.Net

CoinW.Net is a client library for accessing the CoinW REST and Websocket API.

• Response data is mapped to descriptive models
• Input parameters and response values are mapped to discriptive enum values where possible
• High performance
• Automatic websocket (re)connection management
• Client side rate limiting
• Client side order book implementation
• Support for managing different accounts
• Extensive logging
• Support for different environments
• Easy integration with other exchange client based on the CryptoExchange.Net base library
• Native AOT support

The CoinW.Net documentation is the main resource for installing, configuring, and using the library.

The library is targeting both .NET Standard 2.0 and .NET Standard 2.1 for optimal compatibility, as well as the latest dotnet versions to use the latest framework features.

dotnet add package CoinW.Net

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

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

Basic request:

// Get the ETH/USDT ticker via rest request
var restClient = new CoinWRestClient();
var tickerResult = await restClient.SpotApi.ExchangeData.GetTickersAsync();
var lastPrice = tickerResult.Data.Single(x => x.Symbol == "ETH_USDT").LastPrice;

Place order:

var restClient = new CoinWRestClient(opts => {
	opts.ApiCredentials = new CoinWCredentials("APIKEY", "APISECRET");
});

// Place Limit order to go long for 0.1 ETH at 2000
var orderResult = await restClient.FuturesApi.Trading.PlaceOrderAsync(
    "ETHUSDT",
    PositionSide.Long,
    FuturesOrderType.Plan,
    0.1m,
    1,
    price: 2000);

WebSocket subscription:

// Subscribe to ETH/USDT ticker updates via the websocket API
var socketClient = new CoinWSocketClient();
var tickerSubscriptionResult = socketClient.SpotApi.SubscribeToTickerUpdatesAsync("ETH_USDT", (update) => 
{
  var lastPrice = update.Data.LastPrice;
});

For more examples and explanations, continue with the CoinW.Net documentation or browse the compilable repository examples.

CoinW.Net includes AI-oriented documentation and examples for code generation tools:

See cryptoexchange-skills-hub for installable skills.

The CryptoExchange.Net Shared API V2 provides exchange-agnostic interfaces and models for common operations such as retrieving tickers, order books and balances, placing orders, and subscribing to market updates.

V2 uses a strict interface per capability. The SharedApi property on each API surface therefore exposes only the operations or subscriptions that surface actually supports. ICoinWSharedApiClient groups the exchange's Shared API surfaces for dependency injection and runtime capability lookup.

using CoinW.Net.Clients;
using CryptoExchange.Net.SharedApis;

using var restClient = new CoinWRestClient();
IGetTickerRest tickerClient = restClient.SpotApi.SharedApi;

var symbol = new SharedSymbol(TradingMode.Spot, "ETH", "USDT");
var result = await tickerClient.GetTickerAsync(
    new GetTickerRequest(symbol));

if (!result.Success)
{
    Console.WriteLine(result.Error);
    return;
}

Console.WriteLine(result.Data.LastPrice);

The request and response models belong to CryptoExchange.Net.SharedApis, so the same operation can accept another exchange's IGetTickerRest implementation. When using dependency injection, inject ICoinWSharedApiClient to access all of the exchange's Shared API surfaces or inject a capability such as IGetTickerRest directly. Use GetCapability on the aggregate when the operation, transport, or trading mode is selected at runtime.

CoinW.Net is based on the CryptoExchange.Net base library. Other exchange API implementations based on the CryptoExchange.Net base library are available and follow the same logic.

CryptoExchange.Net also provides shared access to different exchange APIs.

When using multiple of these API's the CryptoClients.Net package can be used which combines this and the other packages and allows easy access to all exchange API's.
