Backend Chat AI

📘 README available in Spanish

This project implements the backend of a chat system with artificial intelligence using FastAPI and OpenAI. It allows managing conversations between users and an advanced language model, providing automatic responses.

Technologies

• FastAPI: Framework for building fast and modern APIs in Python.

• OpenAI API: For generating automatic responses using language models.

• Python 3.13.3

• CORS Middleware: Enables secure communication between frontend and backend.

Environment Variables

Create the .env file in the root directory and define the following variable:

OPENAI_API_KEY=<YOUR_OPENAI_API_KEY>

Installation

1. Clone the repository:

git  clone  https://github.com/nuriadevs/backend-chat.git

cd  backend-chat

2. Install dependencies:

pip  install  -r  requirements.txt

Start

Start the development server:

uvicorn  app.main:app  --reload  --port  8000

The backend will be available at http://localhost:8000.

Endpoints

• POST /chat: Send messages and receive responses from the AI model.

• GET /: Test endpoint to verify that the backend is active.

Tests

To run the test suite, execute the following in the application's root directory:

pytest  or  pytest  -s

Summary

• Don't forget to create the .env file with the OpenAI variable.

• This project is designed to be scalable.
