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: 'twitter',
accountId: 'your-x-account-id'
}],
content: 'Building the future with APIs! 🚀 #TechTrends #API #Innovation',
mediaItems: [{
type: 'image',
url: 'https://your-tweet-image.jpg'
}],
scheduledFor: '2024-01-15T12:00:00Z'
})
});
const result = await response.json();
console.log('Tweet scheduled:', result.id);Common Questions
- Why use Zernio instead of X's API directly?
- └X's API costs $100+/month for Basic access, requires developer portal approval, and changes frequently. Zernio abstracts all this complexity-one simple endpoint for scheduling tweets on X and 11 other platforms at a fraction of the cost.
- Do you support Twitter threads?
- └Yes! Create Twitter threads using platformSpecificData.threadItems in your API request. Each item becomes a connected reply in the thread. We handle all the reply-chaining logic.
- Can I attach media to X posts?
- └Yes! X supports up to 4 images per post or 1 video. Zernio handles media optimization and upload automatically. Videos can be up to 2 minutes and 20 seconds.
- How does authentication work?
- └Your users authenticate via our hosted OAuth flow. We manage token refresh, expiration, and re-authentication automatically. You never touch X's OAuth directly.
- Can I cross-post to other platforms?
- └Absolutely! Include X alongside TikTok, Instagram, Facebook, YouTube, LinkedIn, Threads, Reddit, Pinterest, and Bluesky in one API call.
