Three steps

  1. Create a free 0n3 account and connect Square. Paste a key or sign in; it lands in your vault, encrypted.
  2. Install 0n3 into Grok Bot (xAI). xAI's always-on Grok Bot. Add 0n3 as a custom connector once, and your Bot can use every app you added, around the clock.
  3. Ask Grok Bot (xAI): whoami. Then: "Create a payment in Square".
Add 0n3 to Grok Bot (desktop app)
  1. Open Grok Bot on your computer. In the sidebar, click Connect apps.
  2. At the bottom, click Add a custom connector.
  3. For Name, type 0n3. For Type, pick Remote HTTPS. For Server URL, type https://0n3.app/mcp.
  4. Under HTTP headers, add Authorization with the value Bearer <your 0n token>
  5. Click Add plugin.
Then try it: send your Bot this
  1. "Use 0n3: who am I, and which apps can you reach?"
  2. "Every weekday at 8, use 0n3 to list today's CRM appointments and new Stripe payments, and post a summary to me."

The line above carries a placeholder; 0n3.app/install mints a real key named for Grok Bot (xAI) and fills it in.
