HTTP Status Code 418 I’m A Teapot

The error code “418 I’m a teapot” should appear if you try to brew coffee using a teapot. The body of the resulting entity may be short and stout.

The HTTP 418 I’m a teapot client error code implies that the server will not brew coffee since it is always a teapot. When a combination coffee/tea pot runs out of coffee, it should return 503. This mistake is a reference to the 1998 and 2014 April Fools’ hoaxes on the Hyper Text Coffee Pot Control Protocol.

Some websites use this answer to respond to requests that they don’t want to deal with, such as automated inquiries.

Larry Masinter first established the 418 HTTP status code on April 1st, 1998 (April Fools’ Day) in RFC 2324 (“Hyper Text Coffee Pot Control Protocol (HTCPCP/1.0)”) and RFC 7168 (“The Hyper Text Coffee Pot Control Protocol for Tea Efflux Appliances (HTCPCP-TEA)”) protocols.

Per Wikipedia: List of HTTP status codes: #418

When the server is asked to brew coffee, code 418 is used to return “I’m a teapot.” The HTTP methods for interacting with such a server have to be changed to allow the command “BREW” to be used instead of the standard “POST,” with a disclaimer that using POST in this scenario is discouraged. Instead of delivering information, the command “GET” now “retrieves” a coffee from the server. The command “PROPFIND” is used to return coffee information, and the command “WHEN” is used to say when the HTCPCP (Hyper Text Coffee Pot Control Protocol) should cease pouring coffee, recalling the traditional “Say when” of preparing someone else’s coffee.

418 is part of the 4xx code set, which indicates that the client has made a mistake. 418 intends to make it apparent that you won’t be getting coffee from a teapot anytime soon, and you might want to try somewhere else, just like the famous 404 tells your browser know it’s seeking items that don’t exist.
