Generate Daily Prayer

Generate a daily prayer (text only).

This endpoint creates a personalized prayer (approximately 1 minute long) that ends with "Amen". Audio is fetched separately via the /daily-prayer/audio endpoint to improve response time.

When for_names is supplied the prayer is intercessory — written for those people rather than for the user — and bypasses the daily prayer cache so it neither replays nor overwrites the user's own daily prayer.

Args: request: Prayer request (sendAudio flag is ignored) current_user: Authenticated user

Returns: PrayerResponse containing prayer_text only (audio_base64 will be None)
