HTTP Status Lookup

HTTP Status Lookup is part of Toolspire and is ready as soon as this page loads. This is a fixed list of codes people meet, not a live request to a server. 200 is OK. 301 is a permanent redirect. 500 is an internal server error.

What you can do here

A fixed table

No network call. The meaning cannot drift with a website.

The teapot is included

Because people look it up, not because a server should send it.

Unknown stays unknown

499 is not given a guess.

The sequence

How to use the HTTP Status Lookup

  1. 1

    Type the three-digit code

    404 is the sample.

  2. 2

    Try 418

    You should see the teapot.

  3. 3

    Try 499

    You should see that it is not on the list.

Worth knowing

  • HTTP Status Lookup on Toolspire: 404 is Not Found.
  • 418 is I’m a teapot, the joke code from the coffee-pot protocol.
  • 200 is OK. 301 is Moved Permanently. 500 is Internal Server Error.
  • A code not on the list returns Not in this short list, rather than a made-up reason.

The codes this list actually has

The list covers the codes that show up in ordinary debugging: 200, 201, 204, 301, 302, 304, 400, 401, 403, 404, 405, 408, 409, 418, 429, 500, 502, 503 and 504. Each has the short reason phrase. A code outside that set is reported as absent. The page does not connect to the host that sent the code.
