X publishing as software
Codex runs postqueen commands, reads the JSON results and verifies each step, so your X pipeline behaves like any other task it automates in CI or cron.
XAutomate X with Codex
Point Codex at the postqueen CLI and it creates, schedules and verifies X posts as one repeatable task you can rerun any time.
Quick start
Set up the CLI inside the workspace Codex uses, then describe the X outcome you want in the task prompt.
Codex session
# Inside a Codex sessionnpm install -g postqueenexport POSTQUEEN_API_KEY=your_api_key # Then prompt:# "Create this week's X posts# from notes.md and schedule them# with postqueen"What Codex can run on X
Windows that fit X
Tell Codex when your followers are most active and it schedules posts into that window on X, day after day, without reminders.
Media attached, sized right
Images upload in the same postqueen call, so X posts arrive with their media in place instead of a bare link.
Drafts until you are ready
Ask Codex for drafts only. They sit on the postqueen calendar unscheduled, so you can edit them and pick the time yourself, and nothing reaches your followers on X until you do.
Three steps to a full queue
Discover X
Codex calls postqueen to list your connected accounts and sees what X supports, so drafts start from real capabilities, not guesses.
Draft with Codex
Give it the brief. The agent writes X-shaped posts and proposes publish times that match when your followers are around.
Check and publish
Look over the queue on the postqueen calendar and change anything you want. postqueen publishes each post at its time, and Codex can pull the results after.
What X allows
Codex reads these limits from postqueen before it composes, so a draft that would be rejected never reaches the queue.
- Post length
- 280 characters on a standard account, up to 25,000 characters with X Premium
- Media per post
- Up to 4 images, or 1 GIF, or 1 video (images and GIFs cannot be mixed)
- Video length
- Up to 2 minutes 20 seconds on a standard account, longer for Premium subscribers
- Threads
- Chain any number of posts, published in order as native replies
- Alt text
- Up to 1,000 characters of image description per attachment
- API access
- Publishing runs on the official X API, so self-hosted installs connect with their own X developer app

F.A.Q.
Frequently asked questions
How does Codex connect X to postqueen?
Install the postqueen CLI where Codex runs commands and export your API key. Every command returns JSON, so the agent can create, schedule and list X posts reliably.
Can Codex schedule X posts at exact times?
Yes. Give it exact slots or a rule like mornings at nine and it sets publish times on the posts it creates, so your followers see them at the right moment.
Will Codex publish to X on its own?
Only if you ask it to. Tell it to save drafts and nothing is scheduled: the posts wait on the calendar until you set a time. Tell it to schedule, and they go out at the times you can see, which is the setup most people move to once they trust the output.
Can one brief cover X and other channels too?
Yes. postqueen connects 30 channels, so Codex can turn the same brief into X posts plus adapted versions for every other channel you run.
Does Codex access cost extra on postqueen?
No. The agent uses your regular API key and plan limits: unlimited posts on every plan, and channel counts from 5 on Creator up to uncapped on Ultimate.
Can I cross-post from X to Bluesky, Mastodon and Threads?
Yes. Write once, select X plus Bluesky, Mastodon or Threads as destinations, and adjust the wording per network before scheduling. Each one gets a real native post rather than a link pointing back to X.
What X analytics does postqueen show?
postqueen reports the post-level metrics X's API exposes for your own account, such as likes, reposts, replies and impressions. Use it to compare formats and posting slots instead of guessing.
