Installation

dotnet add package FutuCopy.Api.Client

Quick Start

Standalone Usage

using FutuCopy.Api.Client;

using var client = new FutuCopyClient("https://your-server.futucopy.com", "fc_pk_your_api_key_here");

// Check API health
var health = await client.GetHealthAsync();
Console.WriteLine($"API Status: {health.Status}, Version: {health.Version}");

// List all accounts (includes positions and orders)
var accounts = await client.GetAccountsAsync();
foreach (var account in accounts)
{
    Console.WriteLine($"{account.AccountName}: Balance={account.Balance:C}, PnL={account.DailyPnL:C}");
    Console.WriteLine($"  Positions: {account.Positions.Count}, Orders: {account.Orders.Count}");
}

// Get detailed account info with positions and orders
var detail = await client.GetAccountAsync(accountId: 1);
foreach (var position in detail.Positions)
{
    Console.WriteLine($"{position.Symbol}: {position.Quantity} @ {position.AveragePrice}, PnL={position.UnrealizedPnL:C}");
}

Dependency Injection (ASP.NET Core, Worker Services)

// In Program.cs
builder.Services.AddFutuCopy(options =>
{
    options.ApiKey = builder.Configuration["FutuCopy:ApiKey"]!;
    options.BaseUrl = builder.Configuration["FutuCopy:BaseUrl"]!; // your dedicated instance URL
});

// In your service or controller
public class TradingDashboard(IFutuCopyClient futuCopy)
{
    public async Task<AccountResponse> GetAccount(int id)
        => await futuCopy.GetAccountAsync(id);
}

Error Handling

The client throws typed exceptions for different error scenarios:

using FutuCopy.Api.Client.Exceptions;

try
{
    var account = await client.GetAccountAsync(999);
}
catch (FutuCopyAuthenticationException ex)
{
    // 401 - Invalid or missing API key
    Console.WriteLine($"Auth failed: {ex.Error?.Code}");
}
catch (FutuCopyNotFoundException ex)
{
    // 404 - Account not found
    Console.WriteLine($"Not found: {ex.Error?.Message}");
}
catch (FutuCopyRateLimitException)
{
    // 429 - Too many requests
}
catch (FutuCopyApiException ex)
{
    // Other API errors
    Console.WriteLine($"API error {ex.StatusCode}: {ex.Message}, RequestId: {ex.RequestId}");
}

Configuration

var client = new FutuCopyClient("https://your-server.futucopy.com", "fc_pk_your_key", new FutuCopyClientOptions
{
    Timeout = TimeSpan.FromSeconds(30) // default
});

When using DI, you can chain additional HttpClient configuration:

builder.Services.AddFutuCopy(options =>
{
    options.ApiKey = builder.Configuration["FutuCopy:ApiKey"]!;
})
.ConfigurePrimaryHttpMessageHandler(() => new HttpClientHandler
{
    // Custom handler settings (proxy, certificates, etc.)
});

Authentication

1. Log in to your FutuCopy dashboard
2. Navigate to Pro Server > API Access
3. Generate an API key (format: fc_pk_...)

Security: Never hardcode API keys in source code. Use environment variables, user secrets, or a configuration provider:

options.ApiKey = Environment.GetEnvironmentVariable("FUTUCOPY_API_KEY")!;

Requirements

• .NET 10.0 or later
• FutuCopy Pro plan with API access enabled
• API key (format: fc_pk_*)
