This project was bootstrapped with Visual Studio to give the boilerplate code for building REST API endpoints. The endpoint /GetStockData will return historial stock data given the parameters tickerSymbol, startDate, and fromDate which are used to determine the daily returns for the date range specified (inclusive).
To fetch the data needed, I have used iexcloud API endpoints. This data is then formatted and pruned to suit the specifications of the desired output. More specifically, I am gathering the data with the `$"https://cloud.iexapis.com/stable/stock/{symbol}/chart/{rangeSlug}?token={tokenSecret}"; endpoint. With the parameters for that uri being:
symbol-> the ticker symbol for a given stock (aapl, msft, tsla, etc.).rangeSlug-> the range of data we want to fetch given our date bounds (5 days, 1 month, 3 months, 6 months, 1 year, year to date).token-> our API token that gives authorization to execute the query and get the JSON data back.
Most of what is needed will be automatically set up by building a new ASP.NET Core Web API project in Visual Studio.
- Docker Desktop
- Visual Studio
- C# .NET Core
- Microsoft.AspNet.WebApi.Client
- Microsoft.VisualStudio.Azure.Containers.Tools.Targets
- Swashbuckle.AspNetCore
- Microsoft.ASPNetCore.App
- Microsoft.NETICore.App
In Visual Studio, using Ctrl + F5 will boot up a docker container and open the Swagger UI spec where parameters can easily be passed into the endpoint.
if cURL is preferred, a sample cURL command, would look something like:
curl -X 'GET' \
'https://localhost:49155/Stock?tickerSymbol=msft&startDate=2023-04-10&endDate=2023-04-21' \
-H 'accept: text/plain' -k
This will return json data for Microsoft's daily returns from April 10, 2023 - April 21, 2023
-k is used to avoid errors for a missing SSL/TLS certificate when running the command outside of Visual Studio/Docker container.
I have attached a sample data file for what is being returned in this sample data file.
