🚀 Getting Started

Follow these simple steps to get the API up and running on your local machine.

Prerequisites

• Ensure you have Python 3.8+ installed on your system.

Installation & Setup

1. Clone the repository:

   git clone <your-repository-url>
   cd <repository-folder>

2. Create a virtual environment (recommended):

   # On macOS and Linux
   python3 -m venv venv
   source venv/bin/activate
   
   # On Windows
   python -m venv venv
   .\venv\Scripts\activate

3. Install the required packages: The requirements.txt file contains all the necessary dependencies.

   pip install -r requirements.txt

4. Run the API server:

   uvicorn main:app --reload

   The --reload flag enables automatic server restarts on code changes. The API will now be live at http://127.0.0.1:8000.
