YFinance.Yahoo

Unofficial C# client for Yahoo Finance API with dependency injection support.

Installation

dotnet add package YFinance.Yahoo

Usage with Dependency Injection

1. Register Services

using Microsoft.Extensions.DependencyInjection;
using YFinance.Yahoo;
using YFinance.Yahoo.Services;
using YFinance.Yahoo.Interfaces;

var services = new ServiceCollection();

// Register YahooClient as singleton (important to avoid IP bans)
services.AddSingleton<IYahooClient, YahooClient>();

// Register services
services.AddSingleton<IInfoService, InfoService>();
services.AddSingleton<IQuoteService, QuoteService>();

var serviceProvider = services.BuildServiceProvider();

2. Use the Services

// Get services from DI container
var infoService = serviceProvider.GetRequiredService<IInfoService>();
var quoteService = serviceProvider.GetRequiredService<IQuoteService>();

// Get stock information
var tickers = new[] { "NVDA", "AAPL", "GME" };
var info = await infoService.GetInfoAsync(tickers);
var quotes = await quoteService.GetQuoteAsync(tickers);

Why Singleton?

YahooClient should be registered as a singleton to:

  • Avoid creating multiple HttpClient instances
  • Prevent IP bans from Yahoo Finance
  • Reuse cookies and cached crumb tokens efficiently

Namespaces

  • YFinance.Yahoo - Main client implementation (YahooClient)
  • YFinance.Yahoo.Interfaces - Service interfaces (IYahooClient, IInfoService, IQuoteService)
  • YFinance.Yahoo.Services - Service implementations (InfoService, QuoteService)
  • YFinance.Yahoo.Entities - Data models (Info, Quote, History)
