Can Muse post to Instagram and Facebook?

Yes. Muse links your Meta accounts itself; through xpost it can also draft a post, reel, story or carousel for them, and every one comes back to you with a receipt and the live link.

Can Muse post to X, LinkedIn or TikTok?

Yes. The same message connects all nine networks: Instagram, Facebook, Threads, X, LinkedIn, TikTok, YouTube, Bluesky and Pinterest. One request can go to several accounts at once.

Why does Muse need an API key?

Muse connects services outside Meta using credentials you provide, so it identifies itself to xpost with a key you make there. The key can create posts and read receipts; it can never approve a post.

Is it safe to let Muse post for me?

Yes. You can see every post Muse creates in xpost, get a link when it goes live, and turn on approvals whenever you want to review posts before publishing.

Muse launched on 8 September 2026 for adults in the United States, with more regions to follow. xpost works with it wherever Meta offers it; the connector costs nothing extra and your first post is free.

Post to social media from Muse.

Meta's personal agent lives alongside Facebook, Instagram and Threads. Paste one message, hand it an xpost key, and it can post to those and six more networks — and you see every post, before it goes out or the moment it has.

Set up xpost in Muse

Three steps, about two minutes. No settings to find: you paste one message and hand over a key.

How the command line and the paste-in message work

1
Paste the setup message
Copy this message and paste it into Muse. Muse connects services with credentials you provide, and this tells it where xpost is and what the rules are.
Set up xpost so you can post to my social accounts. The REST API is https://xpost.to/api/v1 (spec at https://xpost.to/api/v1/openapi.json), authenticated with an Authorization: Bearer YOUR_KEY header. If you can run commands, `npx xpost` wraps it and `npx skills add xpost-to/xpost-agent` installs the workflow. Ask me for my xpost API key and set it as XPOST_API_KEY before doing anything. Start with the accounts list. Creating a post sends it, so give me the link it hands back and tell me when it goes out — and never say a post is published until the receipt says so.
2
Give Muse a key
Muse asks for your xpost API key. Make one under Project → AI agent → Keys and paste it. The key can create posts and read receipts; it can never approve one.
3
Ask for a post
Say what you want, for which accounts and when. It comes back with a link to the post. Switch approvals on and that link is where you approve it.
