Why Zernio vs AT Protocol Direct?

AT Protocol Direct

  • Complex authentication with DID and app passwords
  • Rate limits and PDS (Personal Data Server) management
  • Blob uploads with specific encoding requirements
  • Rapidly evolving protocol with frequent changes
  • Build separate integrations per platform

Zernio API

  • Simple API key - start in 30 seconds
  • Automatic retries & queue management
  • Upload directly - we handle AT Protocol blobs
  • Zero maintenance forever
  • One API for 14 platforms

Save 4-6 weeks of development. Ship today, not next month.

Code Example

const response = await fetch('https://zernio.com/api/v1/posts', {
  method: 'POST',
  headers: {
    'Authorization': 'Bearer YOUR_API_KEY',
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    platforms: [{
      platform: 'bluesky',
      accountId: 'your-bluesky-account-id'
    }],
    content: 'Hello Bluesky! This was posted via Zernio API.',
    scheduledFor: '2025-10-15T16:00:00Z'

Common Questions

Why use Zernio instead of AT Protocol directly?
AT Protocol requires learning decentralized concepts, managing DIDs, and implementing record creation. Zernio abstracts all this complexity-one simple endpoint for scheduling posts on Bluesky and 11 other platforms.
How does Bluesky authentication work?
Bluesky uses App Passwords instead of OAuth. Your users create an App Password in their Bluesky settings, and we handle the authentication, token management, and AT Protocol session handling.
What content can I post to Bluesky?
Bluesky supports text posts (up to ~300 characters), images (up to 4 per post), and videos. You can also create threaded conversations using platformSpecificData.threadItems.
Can I cross-post to other platforms?
Absolutely! Include Bluesky alongside TikTok, Instagram, Facebook, YouTube, LinkedIn, X, Threads, Reddit, and Pinterest in one API call.
Are there any posting limits?
Bluesky has reasonable rate limits to prevent spam. Zernio handles these automatically with retries and proper spacing. Your posting frequency depends on your Zernio plan, not Bluesky's limits.
