Introduction
Schedule and publish social media posts on X, LinkedIn, Instagram, Bluesky, Pinterest and TikTok with one API, or let an AI assistant do it over MCP.
FeedHorizon is one API for posting to social networks. You connect your accounts (or your customers' accounts) once, then create posts with a single request: FeedHorizon checks them against each platform's rules, publishes them at the right time, retries when a platform is down, and tells your server what happened through webhooks.
Quickstart
API key, first request and first post in five minutes.
Data model
Organizations, profiles, accounts, posts and targets, and how they fit together.
MCP Server
Let Claude, ChatGPT or Cursor plan and schedule posts for you, no code needed.
API Reference
Every endpoint with its parameters, responses and errors, generated from the code.
Guides
Scheduling
Drafts, scheduled posts, the queue, own text per account, retries.
Media uploads
Import images and videos from a URL or upload them directly.
Connect links
Let your customers connect their accounts without a FeedHorizon login.
Webhooks
Get told when posts publish or fail, and verify signatures.
Platforms
Publishing works on X, LinkedIn, Instagram, Bluesky, Pinterest and TikTok (beta). Facebook, Threads and YouTube are planned. Each platform page lists what you can post, what you need to connect and which errors can come back. The overview compares them in one table.
