General

This C# example library is an SDK for the folidata finance API service. With this SDK you can download end-of-day historic stock prices and prices for other assets like cryptos, indices, etc.

Requirements

To use this API you need an API key. You can register for a free API key at www.folidata.com. Actually, the site language is in German.

With a free account you can use this API for 100 API calls a day. For more API calls you can submit for a paid package.

Documentation

A full documentation is available under this link (actually in German). But the API is easy to use:

Init

With the following code, you init the http client with your personal API key:

using Folidata;
var key = "YOUR_API_KEY";
var api = new FolidataApi(key);

List of stock exchanges and supported symbols

To get the full list of supported exchanges use this code:

var exchanges = await _api.GetExchangeAsync();

Then you can get all the symbols of a stock exchange:

var exchanges = await _api.GetSymbolsAsync("US");

Other supported lists to get the supported symbols:

• Crypto GetCryptosAsync()
• Forex Pairs GetForexAsync()

Historical End-Of-Day Prices

Just one line of code is enough to get the all historic prices for the apple stock.

var prices = await api.GetPricesAsync("AAPL.US");

To get data for a specific day:

var prices = await api.GetPriceAsync("AAPL.US",new DateTime(2022, 01, 02));

For a specific time range:

var prices = await api.GetPricesAsync("AAPL.US",new DateTime(2021, 01, 02), new DateTime(2022, 06, 01));

Sort the result:

var prices = await api.GetPricesAsync("AAPL.US", new DateTime(2021, 01, 02), new DateTime(2022, 06, 01), Folidata.Utils.SortMode.DESC);

Limit the results:

var prices = await api.GetPricesAsync("AAPL.US", new DateTime(2021, 01, 02), new DateTime(2022, 06, 01), Folidata.Utils.SortMode.DESC, 100);

All given parameters/methods are also possible in the following methods:

• GetCryptoPricesAsync("SHIB-USD")
• GetForexPricesAsync("USDEUR")
• GetIndexPricesAsync("GDAXP")

Key State

To check your current limits and datapoints count:

var state = await api.GetKeyStateAsync();
