Why am I getting 400 'Message required'?

The chat request had no message, or it was empty. Send { "message": "Is it safe to leave cooked rice out overnight?" } as JSON.

Last updated November 9, 2026

Fix

{ "message": "Your question" }

Scoring text you already have? Use /api/score or /api/evaluate with responseText.
