Blazor Stock Chart Viewer with EODHD and Syncfusion

Add stock charts to your Blazor .NET 9 applications using the end-of-day market data from the EODHD API and the Syncfusion Stock Chart component.

The project integrates the Syncfusion Blazor Stock Chart with the data fetched from the EODHD API, offering an interactive chart experience for visualizing candle and volume data for any supported stock ticker.

Overview

Configuration

The backend project WebAPI uses EODHD's historical data API, which requires configuration via appsettings.json:

"EodhdSettings": {
  "BaseUrl": "https://eodhd.com/api",
  "ApiToken": "your_api_token"
}

By default, the API token is set to "demo" for testing purposes, but you should sign up for a personal API key.

In the Blazor project WebUI, Syncfusion components are used to render the interactive stock chart. You must register either a commercial license or a free community license. This is done in Program.cs:

Syncfusion.Licensing.SyncfusionLicenseProvider.RegisterLicense("Your Syncfusion License");

API Documentation

The backend exposes a clean API for fetching historical stock prices from EODHD, including support for filtering by period, date range, and sort order.
