Look up a status, pick the right one for an API, or hit a live endpoint that actually returns it. Add ?code=418 to this URL and the response is that status — useful for curl, interceptors, and “what does my client do on 503?” Nothing here phones home except the Try it fetch to this same page.
Which class?
April Fools’ HTCPCP: a teapot refuses to brew coffee. The body MAY be short and stout. IANA reserved 418 for this joke.
When to use
Easter eggs, never as a real API error.
Don’t
Production errors should be 400, 403, 501, or 503 — not 418.
