Smitline for Meta Muse.

Can Meta Muse make phone calls? Not on its own. With Smitline connected, Meta Muse can make phone calls for you: tell it who to call and what you need, Smitline calls the US or Canadian number in a natural voice, and Meta Muse tells you what was said and agreed. What you need: Muse in the US or Canada, in the app or on the web. A Smitline API key.

Calls use prepaid credit, by the second while connected.

Illustration: setting up Smitline in Meta Muse. You send Muse: Set up Smitline as a custom connector: smitline.com/agents. Then: Secure Credentials, paste your key. The result: connected with an API key. Muse can make phone calls.

Set it up

Smitline is in private beta: signing in needs an invite, and the invite says where to make the API key for YOUR_SMITLINE_KEY. Get early access

Good to know: In Settings → Permissions, keep Muse asking before actions, so you approve each call before it’s placed.

From Meta: Muse Help Center: connectors (opens in a new tab). Checked 1 November 2026.

  1. In your Smitline dashboard, open Connect → API keys and click Create key. Keep the page open: the key is shown once.

  2. In Muse, send this message:

    Set up Smitline as a custom connector: https://smitline.com/agents

  3. Muse reads the setup page and asks for your key. Paste it into Muse’s Secure Credentials prompt, never into the chat.

  4. Approve the connector, then try it: “Use Smitline to call my phone for a quick test.”

Then ask Muse to make a call

It says it’s an AI calling for you and follows the calling rules. Ideas: what people hand over. Another app? Pick yours. Everything else, from following a call live to the full list of tools: the docs.
