## ✨ What is nzrApi?

**nzrApi** is a powerful, production-ready Python framework specifically designed for building AI-powered APIs. It combines the best of modern web frameworks with specialized features for AI model integration, making it the perfect choice for developers who want to build scalable AI services with minimal complexity.

### 🎯 Key Features

- 🤖 **Native AI Model Integration** - First-class support for multiple AI providers and custom models
- 🔄 **Model Context Protocol (MCP)** - Built-in MCP implementation for seamless n8n integration
- ⚡ **High Performance** - Async/await throughout with ASGI compliance 
- 📊 **Context Management** - Persistent conversation contexts with automatic cleanup
- 🛡️ **Production Ready** - Rate limiting, authentication, monitoring, and error handling
- 🗄️ **Database Integration** - SQLAlchemy async with automatic migrations
- 🎨 **DRF-Inspired Serializers** - Familiar, powerful data validation and transformation
- 🚀 **Auto-Generation** - CLI tools for rapid project scaffolding
- 🐳 **Cloud Native** - Docker support with production configurations

## 🚀 Quick Start

### Installation

```bash
pip install nzrapi
```

### Create Your First AI API

```bash
# Create a new project
nzrapi new my-ai-api

# Navigate to project
cd my-ai-api

# Run the development server
nzrapi run --reload
```

Your AI API is now running at `http://localhost:8000`! 🎉

### Hello World Example

```python
from nzrapi import NzrApiApp, Router

app = NzrApiApp(title="My AI API")
router = Router()

@router.post("/chat")
async def chat(request):
    data = await request.json()
    
    # Use built-in AI model
    model = request.app.ai_registry.get_model("default")
    result = await model.predict({"message": data["message"]})
    
    return {"response": result["response"]}

app.include_router(router)

if __name__ == "__main__":
    import uvicorn
    uvicorn.run(app, host="0.0.0.0", port=8000)
```

## 🤖 AI Model Integration

nzrApi makes it incredibly easy to work with AI models:

```python
from nzrapi.ai.models import AIModel

class MyCustomModel(AIModel):
    async def load_model(self):
        # Load your model (PyTorch, HuggingFace, OpenAI, etc.)
        self.model = load_my_model()
        self.is_loaded = True
    
    async def predict(self, payload, context=None):
        # Make predictions with optional context
        result = self.model.generate(payload["prompt"])
        return {"response": result}

# Register and use
app.ai_registry.register_model_class("custom", MyCustomModel)
await app.ai_registry.add_model("my_model", "custom", config={...})
```

### Supported AI Providers

- ✅ **OpenAI** (GPT-3.5, GPT-4, etc.)
- ✅ **Anthropic** (Claude models)
- ✅ **HuggingFace** (Transformers, Inference API)
- ✅ **Custom Models** (PyTorch, TensorFlow, etc.)
- ✅ **Mock Models** (for development and testing)

## 🔄 Model Context Protocol (MCP)

nzrApi implements the Model Context Protocol for stateful AI interactions:

```python
# MCP-compliant endpoint
@router.post("/mcp/{model_name}/predict")
async def mcp_predict(request, model_name: str):
    # Automatic context management
    mcp_request = MCPRequest(**(await request.json()))
    
    # Retrieve conversation context
    context = await get_context(mcp_request.context_id)
    
    # Make prediction with context
    model = request.app.ai_registry.get_model(model_name)
    result = await model.predict(mcp_request.payload, context)
    
    # Return MCP-compliant response
    return MCPResponse(
        request_id=mcp_request.request_id,
        context_id=mcp_request.context_id,
        result=result
    )
```

## 🎨 Powerful Serializers

nzrApi provides robust data validation:

```python
from nzrapi.serializers import BaseSerializer, CharField, IntegerField

class ChatRequestSerializer(BaseSerializer):
    message = CharField(max_length=1000)
    user_id = CharField(required=False)
    temperature = FloatField(min_value=0.0, max_value=2.0, default=0.7)
    
    def validate(self, data):
        # Custom validation logic
        return data

# Use in endpoints
@router.post("/chat")
async def chat(request):
    data = await request.json()
    serializer = ChatRequestSerializer(data=data)
    
    if serializer.is_valid():
        validated_data = serializer.validated_data
        # Process with confidence...
    else:
        return JSONResponse(serializer.errors, status_code=422)
```

## 🗄️ Database Integration

Built-in async database support with SQLAlchemy:

```python
from nzrapi.db import Base
from sqlalchemy import Column, Integer, String, DateTime

class ConversationHistory(Base):
    __tablename__ = "conversations"
    
    id = Column(Integer, primary_key=True)
    user_id = Column(String(255), index=True)
    message = Column(Text)
    response = Column(Text)
    created_at = Column(DateTime, default=datetime.utcnow)

# Use in endpoints
@router.post("/chat")
async def chat(request):
    async with request.app.get_db_session() as session:
        # Save conversation
        conversation = ConversationHistory(
            user_id=user_id,
            message=message,
            response=response
        )
        session.add(conversation)
        await session.commit()
```

## 🛡️ Production Features

### Rate Limiting
```python
from nzrapi.middleware import RateLimitMiddleware

app.add_middleware(
    RateLimitMiddleware,
    calls_per_minute=60,
    calls_per_hour=1000
)
```

### Authentication
```python
from nzrapi.middleware import AuthenticationMiddleware

app.add_middleware(
    AuthenticationMiddleware,
    secret_key="your-secret-key"
)
```

### CORS for n8n
```python
from starlette.middleware.cors import CORSMiddleware

app.add_middleware(
    CORSMiddleware,
    allow_origins=["https://app.n8n.cloud"],
    allow_credentials=True,
    allow_methods=["*"],
    allow_headers=["*"]
)
```

## 🔧 CLI Tools

nzrApi includes powerful CLI tools for development:

```bash
# Create new project
nzrapi new my-project --template mcp-server

# Run development server  
nzrapi run --reload --port 8000

# Database migrations
nzrapi migrate -m "Add user table"
nzrapi migrate --upgrade

# Model management
nzrapi models --list
nzrapi models --add openai_gpt4 --type openai

# Project info

{
  "nodes": [{
    "name": "AI Chat",
    "type": "n8n-nodes-base.httpRequest",
    "parameters": {
      "url": "http://your-api.com/api/v1/mcp/gpt4/predict",
      "method": "POST",
      "body": {
        "context_id": "{{ $json.session_id }}",
        "payload": {
          "message": "{{ $json.user_input }}"
        }
      }
    }
  }]
}
```
