Key Features

Loopai provides production-ready infrastructure for AI-powered applications with multi-language SDK support.

1. Multi-Language Client SDKs

Production-ready SDKs for .NET, Python, and TypeScript with modern development patterns.

.NET Client SDK

// Install via NuGet
dotnet add package Loopai.Client

// Dependency injection setup
builder.Services.AddLoopaiClient(options =>
{
    options.BaseUrl = "http://localhost:8080";
    options.Timeout = TimeSpan.FromSeconds(60);
});

// Use in controllers
public class MyController : ControllerBase
{
    private readonly ILoopaiClient _loopai;

    public MyController(ILoopaiClient loopai) => _loopai = loopai;

    [HttpPost]
    public async Task<IActionResult> Classify(string text)
    {
        var result = await _loopai.ExecuteAsync(taskId, new { text });
        return Ok(result);
    }
}

Features:

• HTTP client with automatic retry (Polly v8)
• ASP.NET Core dependency injection
• Exception hierarchy for error handling
• Comprehensive logging integration

Python Client SDK

# Install via pip
pip install loopai

# Async usage
import asyncio
from loopai import LoopaiClient

async def main():
    async with LoopaiClient("http://localhost:8080") as client:
        result = await client.execute(
            task_id="550e8400-e29b-41d4-a716-446655440000",
            input_data={"text": "Buy now!"}
        )
        print(result.output)

asyncio.run(main())

Features:

• Full async/await support with httpx
• Automatic retry with exponential backoff
• Pydantic v2 models with type safety
• Context manager support

TypeScript/JavaScript SDK

// Install via npm
npm install @loopai/sdk

// TypeScript usage
import { LoopaiClient } from '@loopai/sdk';

const client = new LoopaiClient({
  baseUrl: 'http://localhost:8080',
});

const result = await client.execute({
  taskId: '550e8400-e29b-41d4-a716-446655440000',
  input: { text: 'Buy now!' },
});

console.log(result.output);

Features:

• Promise-based async/await API
• Full TypeScript type definitions
• Automatic retry with exponential backoff
• Node.js and browser support

2. SDK Integration Tests

Comprehensive integration testing across all SDKs:

• ✅ 42 Integration Tests: 14 tests per SDK
• ✅ 100% Pass Rate: All tests passing
• ✅ Cross-SDK Compatibility: Verified interoperability
• ✅ CI/CD Ready: GitHub Actions workflows

3. Plugin System for Extensibility

Extensible architecture for custom validation, sampling, and event handling:

// Custom validator plugin
public class MyValidatorPlugin : IValidatorPlugin
{
    public string Name => "my-validator";
    public int Priority { get; set; } = 100;

    public Task<ValidationResult> ValidateAsync(
        ExecutionRecord execution,
        ValidationContext context,
        CancellationToken ct)
    {
        // Custom validation logic
        return Task.FromResult(new ValidationResult
        {
            IsValid = true,
            Message = "Valid"
        });
    }
}

// Register plugins
var registry = services.GetRequiredService<IPluginRegistry>();
registry.Register<IValidatorPlugin>(new MyValidatorPlugin());

Plugin Types:

• Validators: Custom execution result validation
• Samplers: Custom sampling strategies
• Webhook Handlers: Event-driven integrations

4. Batch Operations API

Efficient bulk processing with concurrency control:

var request = new BatchExecuteRequest
{
    TaskId = taskId,
    Items = items.Select(i => new BatchExecuteItem
    {
        Id = i.Id,
        Input = i.Input
    }),
    MaxConcurrency = 10,
    StopOnFirstError = false
};

var response = await client.BatchExecuteAsync(request);
// Returns: TotalItems, SuccessCount, FailureCount, AvgLatencyMs, Results

Available in all SDKs: .NET, Python, TypeScript

5. Multi-Language Program Execution (CodeBeaker)

Execute programs in Python, JavaScript, Go, C# with Docker isolation:

// Execute Python program
var result = await codeBeaker.ExecuteAsync(new ExecuteRequest
{
    Language = "python",
    Code = "print('Hello from Python')",
    Input = inputData,
    TimeoutSeconds = 5
});

Features:

• Multi-language support: Python, JavaScript, Go, C#
• Session pooling for performance
• Docker isolation for security
• Resource limits and timeout control
