Hi Anupam Chugh, thank you very much.

In my article, there’s a section that will show you how to get the below

https://medium.com/_/api/users/{user_id}/profile/stream?limit={follower_load_per_page}&to={last_follower_id}&source=followers&page={page_no}

In it, the user_id is your user id.

As for reporting an invalid ID, it would need an extra call to Medium API to check. Feel free to edit the script to do so if you like.

Thank you once again.
