# Zoe Travel > Private trip-itinerary app. Bots use a **user-issued delegate key** and follow [/travel/bots.md](/travel/bots.md). **Do not use email OTP** — OTP is for humans only. - [Guide for bots](/travel/bots.md): mint/use a delegate key, start a read-only session, read trips, and create/append/poll discussion requests (`open` → `awaiting_optimus` → `zoe_replied` → `closed`). - Optional on create/append: `replyWakeEmail` — one metadata-only wake when Zoe replies (still poll for the body). See bots.md § Optional reply-wake email.
