sc1341/InstagramOSINT ? reverse-engineered prompt

Build me a Python tool that takes an Instagram username and pulls together the public profile details into one saved report.

I want it to show things like the username, display name, profile link, follower and following counts, number of posts, bio, profile picture URL, whether it looks like a business or verified account, whether it is private, whether it was recently joined, any external link, and the business category if it exists. If possible, also download the public photos from the profile.

It should work from the command line with a simple command like python3 main.py --username someuser, and it should save the results as a text file with a dict or JSON style output in a folder for that profile. I also want the core logic to be usable as a Python module in other scripts, with simple methods for getting the data, printing it, saving it, and scraping posts.

Please keep it easy to run, and if you need current docs or Instagram changes, look them up online first.
