Easy.Tools.Finance.CBAR

Easy.Tools.Finance.CBAR is a high-performance, enterprise-ready .NET library designed to fetch official daily exchange rates from the Central Bank of Azerbaijan (CBAR/AMB).

It handles XML parsing, network resilience, and data flattening efficiently, allowing developers to focus on business logic.

Features

  • ** High Performance:** Uses Static XML Serializer caching and Zero-Allocation Span<T> parsing logic to minimize memory pressure.
  • ** Resilience:** Built-in Retry Policy with exponential backoff for handling network glitches.
  • ** Culture Safe:** Parsing logic is strictly Invariant Culture, ensuring stability regardless of the server's regional settings.
  • ** Easy Integration:** Single-line integration with IServiceCollection (Dependency Injection).
  • ** Async & Cancellable:** Full support for async/await and CancellationToken to handle request timeouts properly.
  • ** Multi-Target:** Supports .NET 10, .NET 8, .NET 6, .NET Standard 2.0, and .NET Framework 4.7.2+.

Installation

Install via NuGet Package Manager:

Install-Package Easy.Tools.Finance.CBAR

Or via .NET CLI:

dotnet add package Easy.Tools.Finance.CBAR

Usage

1. Service Registration (Program.cs)

Register the client in your Program.cs. The library provides a fluent extension method.

using Easy.Tools.Finance.CBAR;

var builder = WebApplication.CreateBuilder(args);

// 1. Standard Registration
builder.Services.AddCbarClient();

// 2. OR: Advanced Configuration
builder.Services.AddCbarClient(options => 
{
    options.RetryCount = 3;             // Retry 3 times on failure
    options.RetryDelaySeconds = 2;      // Wait 2 seconds between retries
    // options.BaseUrl = "...";         // Optional: Use a proxy URL if needed
});

var app = builder.Build();

2. Fetching Rates (Controller Example)

Inject ICbarClient into your controllers or services. Ensure you pass the CancellationToken for best practices.

using Easy.Tools.Finance.CBAR;
using Microsoft.AspNetCore.Mvc;

[ApiController]
[Route("[controller]")]
public class CurrencyController : ControllerBase
{
    private readonly ICbarClient _cbarClient;

    public CurrencyController(ICbarClient cbarClient)
    {
        _cbarClient = cbarClient;
    }

    [HttpGet("today")]
    public async Task<IActionResult> GetRates(CancellationToken cancellationToken)
    {
        // Fetch all rates efficiently
        var rates = await _cbarClient.GetTodayRatesAsync(cancellationToken);

        // Example 1: Filter Foreign Currencies (USD, EUR, etc.)
        var currencies = rates.Where(x => x.CurrencyType == "Xarici valyutalar").ToList();

        // Example 2: Filter Precious Metals (Gold, Silver, etc.)
        var metals = rates.Where(x => x.CurrencyType == "Bank metalları").ToList();

        // Get Specific Rates
        var usd = currencies.FirstOrDefault(x => x.Code == "USD");
        var gold = metals.FirstOrDefault(x => x.Code == "XAU"); // XAU = Gold

        if (usd != null)
            Console.WriteLine($"1 USD = {usd.Value} AZN");

        if (gold != null)
            Console.WriteLine($"1 Ounce Gold = {gold.Value} AZN");

        return Ok(rates);
    }
}

Models

The package returns a list of CbarCurrency objects. The data structure is flattened for ease of use.

Property Type Description
Code string The ISO code (e.g., USD, EUR, XAU).
Name string The localized name (e.g., 1 ABŞ dolları, Qızıl).
Value decimal The official exchange rate. Parsed safely using decimal.
