Check Twitter Username Availability Fast

I have a plain text file that contains all the candidate usernames I’m interested in. Your task is simple and focused: run each name through Twitter and tell me whether it’s free or already taken. I’m only concerned with the Twitter platform, so there’s no need to check any other networks.

Please return a clean report that pairs every username with one of two labels—“Available” or “Taken.” A quick turnaround and an accurate pass over the list is all I need; no extra analytics or profile insight is required.
