  summary: "The HTTP status codes most used in practice, grouped by class (informational, success, redirection, client error and server error) with the registered name and a one-line meaning, from 100 Continue and 200 OK to 418 and 511."
  use_when[2]: You need the exact name and meaning of a status code.,You are choosing a response code for an API.
  caveats[2]: Some names changed over time (for example 413 is now Content Too Large and 422 Unprocessable Content); registered names are in the IANA registry.,Codes such as 418 are defined for humor or for specific protocols and are not meant for production use.
