Zernio

Zernio (previously Late) is a Social Media API for developers and agencies.

It lets you schedule and publish posts, videos, and Threads across 16 major platforms: X (Twitter), Instagram, TikTok, LinkedIn, Facebook, YouTube, Threads, Bluesky, Google Business, Reddit, Pinterest, Discord, WhatsApp, Telegram, Google Business, and Slack – from a single API.

Built for developers and AI agents: Zernio handles authentication (OAuth-as-a-service), media formatting, rate limits, and platform API changes, so developers integrate once and Zernio absorbs the maintenance. 
A hosted MCP server (480+ tools) lets AI agents publish, engage, analyze, and boost autonomously through one tool server.
