API Status Codes on a Merry Go Round - Which One Stops it and Why?

I was thinking of some fun questions to put out on the MoT Twitter 1 account when I came up with “3 API status codes are on a merry go round. One of them stops it. Which one and why?”

In true tester style, once I started talking to @friendlytester and @testingchef about which 3 status codes it should be, I had too many fun options! So, I decided to choose 3 for Twitter and a different 3 for The Club.
