# HTTP 418 — I'm a Teapot

**HTTP 418: I'm a Teapot**

An April Fools' joke code from 1998 that servers still return for fun; it is reserved and has no real meaning.

## What 418 actually means

It comes from RFC 2324, the Hyper Text Coffee Pot Control Protocol, published on 1 April 1998: a teapot asked to brew coffee should answer 418. It is not part of HTTP. IANA lists 418 as reserved and unused precisely because so many implementations joked about it that the number could never safely be assigned to anything real. If you have hit one deliberately, some developer left an easter egg; if you hit one by accident, a service is using it as an arbitrary "we are blocking you" code.

## Common causes

- A deliberate easter egg on a site or API
- A service repurposing an unused code to signal an automated block
- A test fixture or a joke endpoint

## If you're just trying to view the page

1. Nothing — it is a joke, not a fault on your side
2. If a real service returned it while blocking you, contact the service; the code itself carries no defined meaning

## If it's your site

1. Do not use 418 for anything real; it is reserved and clients have no defined behaviour for it
2. Use 403 for a refusal or 429 for rate limiting, with a clear error body

## Reference

- **Reason phrase:** I'm a Teapot
- **Category:** 4xx — Client Error

## Common questions

### What does HTTP 418 mean?

An April Fools' joke code from 1998 that servers still return for fun; it is reserved and has no real meaning. It comes from RFC 2324, the Hyper Text Coffee Pot Control Protocol, published on 1 April 1998: a teapot asked to brew coffee should answer 418. It is not part of HTTP.

### How do I fix a 418 error?

Nothing — it is a joke, not a fault on your side

### Is 418 a client error or a server error?

418 is in the 4xx range, which means client error. The request itself was the problem, so retrying it unchanged will usually return the same code.
