    cd Aniworld
    ```

2. **Create and Activate Conda Environment**

    ```bash
    conda create -n AniWorld python=3.11
    conda activate AniWorld
    ```

3. **Install Dependencies**

    ```bash
    pip install -r requirements.txt
    ```

4. **Set Environment Variables**

    ```bash
    # Set your master password (will be hashed automatically)
    set MASTER_PASSWORD=your_secure_password
    ```

5. **Start the FastAPI Server**

    ```bash
    # Development mode with auto-reload
    uvicorn src.server.fastapi_app:app --host 127.0.0.1 --port 8000 --reload

    # Or use the VS Code task: "Run FastAPI Server"
    ```

6. **Access the Application**
    - **Web Interface**: http://localhost:8000
    - **API Documentation**: http://localhost:8000/docs
    - **Alternative API Docs**: http://localhost:8000/redoc

### Alternative: Using VS Code Tasks

If you're using VS Code, you can use the pre-configured tasks:

-   `Ctrl+Shift+P` → "Tasks: Run Task" → "Run FastAPI Server"

## 🔧 Configuration

### Environment Variables

-   `MASTER_PASSWORD` - Your master password (will be hashed automatically)
-   `MASTER_PASSWORD_HASH` - Pre-hashed password (alternative to MASTER_PASSWORD)
-   `JWT_SECRET_KEY` - Secret key for JWT token signing (auto-generated if not set)
-   `LOG_LEVEL` - Logging level (DEBUG, INFO, WARNING, ERROR)

## 🌐 API Usage

### Authentication

1. **Login to get JWT token**:

    ```bash
    curl -X POST "http://localhost:8000/auth/login" \
         -H "Content-Type: application/json" \
         -d '{"password": "your_master_password"}'
    ```

2. **Use token in requests**:
    ```bash
    curl -X GET "http://localhost:8000/api/anime/search?query=naruto" \
         -H "Authorization: Bearer your_jwt_token_here"
    ```

### Key Endpoints
