PostPeer
Social media posting API for cross-platform posting and scheduling.
About PostPeer
PostPeer is a unified API for social media posting, scheduling, and account management. It lets developers add publishing to Twitter/X, Instagram, YouTube, YouTube Shorts, Facebook, TikTok, Threads, Pinterest, LinkedIn, and Bluesky to their own products through a single REST endpoint, handling OAuth flows and token refreshes for connected accounts.
The API supports scheduling posts in advance, real-time webhooks for post status and account connection events, and post analytics (likes, shares, comments, reach). It provides typed SDKs for Node.js and Python, and integrations with Zapier, Make, and n8n for no-code use. It supports multi-account management from a single API key, targeted at agencies and SaaS platforms managing multiple social accounts.
PostPeer also offers tooling for AI agents: a first-party Claude Code skill, a hosted MCP server, and an OpenAPI spec, allowing agents such as Claude, Cursor, or Codex to publish and schedule posts through function-calling or MCP tool calls. Sign-up does not require a credit card and includes free credits to start.
