Create an account with Polygon. Upon account creation, an API key will be provided for you.
You can manage your API keys on the Dashboard
Setup
Install the Polygon.Client NuGet package
Package Manager PM > Install-Package Polygon.Client
Using the API key that was generated for you earlier, you can create a Polygon client in the following ways.
Without Dependency Injection
using var client = new PolygonClient("API KEY GOES HERE");
With Dependency Injection
services.AddPolygonClient("API KEY GOES HERE");
Usage
public class SomeClass
{
private readonly IPolygonClient _polygonClient;
public SomeClass(IPolygonClient polygonClient)
{
_polygonClient = polygonClient;
}
public async Task<PolygonAggregateResponse> DoSomething()
{
// This will get all of the 1-minute bars for 2024-04-20
var request = new PolygonAggregatesRequest
{
Ticker = "SPY",
Multuplier = 1
Timespan = "minute",
From = "2024-04-20",
To = "2024-04-20"
};
var response = await _polygonClient.GetAggregatesAsync(request);
return response;
}
}
