PostBoost Docs

Social Media API for Developers, AI Agents, and Businesses

Introduction
Easy to Use

One API, Eight Platforms

Publish to Instagram, X, LinkedIn, TikTok, Facebook, Pinterest, YouTube, and Mastodon from a single REST endpoint — no separate integrations needed.

Focus on What Matters

Focus on Content, Not Integrations

PostBoost handles OAuth, token refresh, and platform-specific quirks so you don't have to. Just POST your content and it ships.

Powered by React

Built for Developers & AI Agents

SDKs in 9 languages, webhooks for event-driven pipelines, and full compatibility with AI agent frameworks via MCP and standard tool calling.
