Overview

This application provides a FastAPI-based API that allows users to find Instagram accounts they follow that do not follow them back. The API interacts with Instagram using the instaloader library.

Files

• main.py: Contains the FastAPI application and the endpoint to retrieve non-followees.
• instainfo.py: Contains the logic to fetch followers and followees using the instaloader library.
• requirements.txt: Lists the dependencies required to run the application.

Setup

Prerequisites

• Python 3.x
• Instagram account credentials
• An .env file with your Instagram username and password.

Installation

1. Clone the repository:

   git clone https://github.com/your-repository-name.git
   cd your-repository-name

2. Install dependencies:

   pip install -r requirements.txt

3. Create a .env file:

   touch .env

4. Add your Instagram credentials to the .env file:

   USER=your_instagram_username
   PASSWORD=your_instagram_password
   

Running the Application

1. Start the FastAPI server:

   uvicorn main:app --reload

2. Access the API:

   • Endpoint: /non_followees/{user_id}
   • Method: GET
   • Description: Returns a list of Instagram accounts that the user is following but are not following back.

   Example:

   curl http://127.0.0.1:8000/non_followees/your_instagram_username

How It Works

1. Login: The application logs into Instagram using the credentials provided in the .env file.
2. Fetch Data: The get_insta_followers function retrieves the user's followers and followees.
3. Process Data: It calculates the difference between followees and followers to find accounts that the user follows but do not follow back.
4. API Response: The /non_followees/{user_id} endpoint returns the list of non-followees.

Dependencies

• instaloader: Library to interact with Instagram.
• fastapi: Web framework for building APIs.
• uvicorn: ASGI server for serving the FastAPI application.
• python-dotenv: Library to manage environment variables.

Notes

• Ensure that your Instagram account has two-factor authentication disabled, as instaloader may have issues handling it.
• Be cautious of Instagram's API rate limits to avoid being temporarily blocked from making requests.
