Post to social media from Grok.
Paste one message into Grok, hand it an xpost key, and ask for the post — on X, where Grok already lives, and on eight more networks. You see every post it makes.

Set up xpost in Grok
Three steps, about two minutes. No settings to find: you paste one message and hand over a key.
- 1
Paste the setup message
Copy this message and paste it into a new Grok chat. It tells Grok 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.

Give Grok a key
Grok asks for your xpost API key. Make one under Project → AI agent → Keys and paste it. Grok can’t sign in through a browser, so a key is how it identifies itself.

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.
Create your xpost account
Use xpost with your other tools
xpost also works with Claude, ChatGPT, Cursor and other AI tools.
Questions people ask
Yes. With xpost connected, Grok can draft a post or a thread for your X account and schedule it. It comes back with the live link.
