Publora — X / Twitter

X/Twitter platform skill for the Publora API. For auth, core scheduling, media upload, and workspace/webhook docs, see the publora core skill.

Base URL: https://api.publora.com/api/v1
Header: x-publora-key: sk_YOUR_KEY
Platform ID format: twitter-{userId}

⚠️ Twitter/X requires Pro or Premium plan — excluded from the Starter plan.

Platform Limits (API)

⚠️ API limits differ from native app. Design against these.

Property	API Limit	Notes
Text	280 characters	25,000 with Premium account
Images	Up to 4 × 5 MB	All formats auto-converted to PNG (max 1000px width)
Video	2 min (120s) / 512 MB	⚠️ Native allows 2:20 — API is stricter
Video format	MP4, MOV	—
Threading	✅ Auto-split with (1/N) or manual ---	See Threading section
Text only	✅ Yes	—

Common errors:

• This user is not allowed to post a video longer than 2 minutes — trim video to under 120s

Character Counting

X has specific rules Publora handles automatically:

• Standard characters count as 1
• Emojis count as 2 characters
• URLs are counted by their literal length — Publora does NOT apply Twitter's 23-character URL shortening rule

Post a Tweet

await fetch('https://api.publora.com/api/v1/create-post', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json', 'x-publora-key': 'sk_YOUR_KEY' },
  body: JSON.stringify({
    content: 'Just shipped a new feature! 🚀 #buildinpublic',
    platforms: ['twitter-123456789']
  })
});

Threading

Auto-split (content > 280 chars)

Publora automatically splits at paragraph/sentence/word breaks and adds (1/N) markers (e.g., (1/3), (2/3)). 10 characters reserved per tweet for the marker.

Manual split with ---

Use --- on its own line to define exact split points:

body: JSON.stringify({
  content: '1/ Everything I learned building in public this year.\n\n---\n\n2/ First lesson: ship early. Don\'t wait for perfect.\n\n---\n\n3/ Second lesson: your audience is your best product team.',
  platforms: ['twitter-123456789']
})

Explicit markers [n/m]

Use [1/3], [2/3] etc. — Publora detects these and splits at those points exactly (preserves as written).

Media in threads

• Up to 4 images or 1 video attached to the first tweet only
• Subsequent tweets in thread are text-only
• Images and video cannot be mixed in the same tweet

Schedule a Tweet

body: JSON.stringify({
  content: 'Scheduled announcement: our product launches tomorrow! 🎉',
  platforms: ['twitter-123456789'],
  scheduledTime: '2026-03-20T14:00:00.000Z'
})

Platform Quirks

• Pro/Premium required — Twitter/X is excluded from the Starter plan
• All images → PNG: Publora auto-converts all image formats (JPEG, WebP, GIF, etc.) to PNG and resizes to max 1000px width before uploading
• API video limit is 2 min — not 2:20 like native app; videos over 120s will fail
• Emojis count as 2 chars — factor this into character counting
• URLs use literal length — Publora does NOT apply Twitter's 23-char shortening; a 40-char URL counts as 40
• Premium accounts get 25,000 character limit — Publora uses extended limit automatically
• GIF posts count as a video, not an image — different size/count rules apply
• Media only on first tweet when threading
