HTTP/4xx (Client Error)

418 I'm a teapot

An April Fools' joke from RFC 2324 (Hyper Text Coffee Pot Control Protocol); the server refuses to brew coffee because it is a teapot.

❓ Why does this happen?

Some APIs and bot-protection layers return 418 deliberately to reject automated or unwanted requests.

✅ How to fix it

If you receive 418 from a real API, your request was likely flagged as a bot. Add a proper User-Agent and respect rate limits.

Return or handle 418 in your stack

// app/api/resource/route.ts
export function GET() {
  return Response.json(
    { error: "I'm a teapot", status: 418 },
    {
      status: 418
    }
  );
}
