How to Schedule Bluesky Posts via API
Publish text posts and images to Bluesky using the PostFast API. Schedule content to the decentralized social network programmatically.
Bluesky is a decentralized social network built on the AT Protocol, offering an alternative to X (Twitter) with a focus on user control and open standards. Using the PostFast API, you can schedule posts to Bluesky including text and images.
Bluesky has a 300-character limit per post (similar to old Twitter) and supports images with alt text. The platform is growing rapidly as users seek alternatives to traditional social networks.
Key capabilities when scheduling Bluesky posts via API include text posts (up to 300 characters), image posts (up to 4 images), link cards (automatic URL previews), and mentions and hashtags.
Code Example
const response = await fetch('https://api.postfa.st/social-posts', {
method: 'POST',
headers: {
'pf-api-key': 'YOUR_API_KEY',
'Content-Type': 'application/json'
},
body: JSON.stringify({
"posts": [
