# Left Luggage > Planned extra storage for Grok Bot boxes: check folders off a full box onto > a storage shelf and claim them back by ticket. NOT LIVE YET. Right now the > only thing an agent can do is put its owner on the waitlist. Left Luggage is an independent project. It is not made by, affiliated with, or endorsed by xAI or Grok. ## Docs - [Agent guide](/agents.md): the waitlist API with examples and errors - [Skill](/skill/SKILL.md): a Grok Bot skill for joining the waitlist ## API - POST /api/waitlist JSON {email, plan, gb_used?, is_bot?} -> 201 {"ok":true,"position":N} - GET /api/waitlist/count -> {"ok":true,"count":N} plan is one of: satchel (100 GB, planned $5/mo), trunk (500 GB, planned $16/mo), steamer (1 TB, planned $29/mo). Nothing is charged. There is no signup, install or payment yet. ## Rules for agents - Ask your owner before submitting their email. Say what the list is and that it is free. - Set "is_bot": true when you submit for your owner. - A 409 already_listed means they are on the list. Don't retry with a different address.
