VSLee.IEXSharp 1.2.0

IEXSharp

IEX Cloud API for C# and other .net languages. Supports SSE streaming

Prerequisites

This library currently targets netstandard20. Thus, it can be used with .net framework 4.6.1+ and .net core 2.0+

Usage

Prerelease packages are on GH Packages.

Releases are on NuGet

IEX Cloud

public IEXCloudClient(string publishableToken, string secretToken, bool signRequest, bool useSandBox, APIVersion version = APIVersion.stable)

First, create an instance of IEXCloudClient

//For FREE and LAUNCH users
IEXCloudClient iexClient = new IEXCloudClient("publishableToken", "secretToken", signRequest: false, useSandBox: false); 

//For SCALE and GROW users
IEXCloudClient iexClient = new IEXCloudClient("publishableToken", "secretToken", signRequest: true, useSandBox: false); 

//Sandbox
IEXCloudClient iexClient = new IEXCloudClient("publishableToken", "secretToken", signRequest: false, useSandBox: true); 

To use SSE streaming (only included with paid IEX subscription plans)

using (var sseClient = iexClient.SSE.SubscribeStockQuoteUSSSE(symbols: new string[] { "spy", "aapl" }, 
	UTP: false, interval: StockQuoteSSEInterval.OneSecond))
{
	sseClient.Error += (s, e) =>
	{
		Console.WriteLine("Error Occurred. Details: {0}", e.Exception.Message);
	};
	sseClient.MessageReceived += m =>
	{
		Console.WriteLine(m.ToString());
	};
	await sseClient.StartAsync(); // this will block until cancelled
}

Additional usage examples are illustrated in the test project: IEXSharpTest

Legacy (V1)

IEX has deprecated most of their legacy API. However, some functions are still active and you can access them via:

IEXV1RestClient iexClient = new IEXV1RestClient();
