Install in three steps

  1. Create a free account at 0n3.app and connect eBay: paste a key or sign in through a door. It lands in your vault, encrypted.
  2. Open 0n3.app/install, pick your AI. A key is made for that AI alone; copy the line it gives you.
  3. Ask your AI: whoami. It answers with your connected services. Then ask it to inventory items in eBay.
