Installation

1. Clone and install dependencies:

cd Advanced_AI_Agent/implementation/backend
npm install

2. Set up environment variables:

cp env.example .env
# Edit .env with your API keys and configuration

3. Start the development server:

npm run dev

The server will start on http://localhost:3001
