HTTP 418 I'm a Teapot was defined in RFC 2324 (Hyper Text Coffee Pot Control Protocol) as an April Fools' joke in 1998. When a coffee-making request is sent to a teapot, it returns 418 because it's permanently a teapot. Despite being a joke, it's become a beloved part of internet culture. Google hides an Easter egg at google.com/teapot. While not a real production status code, 418 is occasionally used as a fun response for blocked requests or as a placeholder.
Response includes the status code, standard headers (including Content-Type), and a small diagnostic JSON body describing the request and returned status.
