Publora — Bluesky

Bluesky (AT Protocol) 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: bluesky-{did}

Where {did} is your Bluesky Decentralized Identifier (DID), assigned on connection.

Requirements

A Bluesky account connected via username + app password (not your main password)

Generate an app password: Bluesky Settings → App Passwords

Connected through the Publora dashboard

Post a Skeet (text post)

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: 'Building in public on Bluesky today! Links, hashtags, and mentions all auto-detected. #buildinpublic',
    platforms: ['bluesky-did:plc:abc123']
  })
});

Publora automatically detects hashtags, URLs, and @mentions and creates proper AT Protocol facets.

Schedule a Post

body: JSON.stringify({
  content: 'Your Bluesky post here',
  platforms: ['bluesky-did:plc:abc123'],
  scheduledTime: '2026-03-20T11:00:00.000Z'
})

Post with Image

> ⚠️ Bluesky has a strict 1 MB limit per image. Compress to 80–85% JPEG quality.

import requests
HEADERS = { 'Content-Type': 'application/json', 'x-publora-key': 'sk_YOUR_KEY' }
Step 1: Create post
post = requests.post('https://api.publora.com/api/v1/create-post', headers=HEADERS, json={
    'content': 'Check out this photo! 📸',
    'platforms': ['bluesky-did:plc:abc123']
}).json()
Step 2: Get upload URL (make sure image is <1 MB and JPEG/PNG/WebP)
upload = requests.post('https://api.publora.com/api/v1/get-upload-url', headers=HEADERS, json={
    'postGroupId': post['postGroupId'],
    'fileName': 'photo.jpg',
    'contentType': 'image/jpeg',
    'type': 'image'
}).json()
Step 3: Upload
with open('photo_compressed.jpg', 'rb') as f:
    requests.put(upload['uploadUrl'], headers={'Content-Type': 'image/jpeg'}, data=f)

Platform Quirks

Links count in Publora's validation: Bluesky natively excludes link URLs from the char count, but Publora validates against content.length — so links DO consume your 300-char budget. Plan accordingly.

All images → JPEG: Publora converts ALL uploaded formats (PNG, WebP, GIF, TIFF, BMP) to JPEG via sharp before uploading to Bluesky. No manual conversion needed.

Image size is ~976 KB (not 1 MB): Publora enforces 976.56 × 1024 bytes. Compress images to 80–85% JPEG quality to stay under.

Auto-facets: Publora automatically detects #hashtags and URLs and creates proper Bluesky facets with correct byte offsets (handles emojis and multi-byte chars correctly)

altTexts silently ignored in API: The altTexts array in create-post is NOT currently processed — it will be silently ignored. Alt text is only available through the Publora dashboard.

test-connection always fails for Bluesky: Known bug — the validator checks for accessToken but Bluesky uses password. Connection still works for posting; ignore this status.

App password required: Never use your main Bluesky password; create a dedicated app password in Settings → App Passwords

Email verification required before video uploads (one-time step in Bluesky settings)

DID format: Platform ID uses the full DID, e.g. bluesky-did:plc:abc123xyz
