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


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


alternate text is missing from this package README image Prereleases are on GH Packages. A new prerelease is built automatically after every commit.

IEX Cloud

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

First, create an instance of IEXCloudClient

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

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

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

To display historical prices. Read more about DateTime in the wiki.

using (var iexCloudClient = 
	new IEXCloudClient("publishableToken", "secretToken", signRequest: false, useSandBox: false))
	var response = await iexCloudClient.StockPrices.HistoricalPriceAsync("AAPL", ChartRange.OneMonth);
	if (response.ErrorMessage != null)
	   foreach (var ohlc in response.Data)
	      var dt = ohlc.GetTimestampInEST(); // note use of the extension method instead of ohlc.date
	   	  $"{dt} Open: {ohlc.open}, High: {ohlc.high}, Low: {ohlc.low}, Close: {ohlc.close}, Vol: {ohlc.volume}");

To use SSE streaming (only included with paid IEX subscription plans). Extended example in the wiki.

using (var sseClient = iexCloudClient.StockPrices.QuoteStream(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 =>
	await sseClient.StartAsync(); // this will block until Stop() is called

Additional usage examples are illustrated in the test project: IEXSharpTest


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

IEXLegacyClient iexLegacyClient = new IEXLegacyClient();
