Zernio
One API to publish, schedule and analyze across 17 social platforms
Visit website →About
Zernio is a developer-first unified API that lets apps and AI agents publish, schedule and analyze content across 17 social platforms plus 8 ad networks, all through one authentication model and one request shape.
It supports publishing to Instagram, TikTok, YouTube, X/Twitter, LinkedIn, Facebook, Threads, Pinterest, Reddit, Bluesky, WhatsApp, Telegram, Discord, Snapchat and Google Business, plus unified ad campaign management across Meta Ads, Google Ads, TikTok Ads and more.
Zernio also offers a hosted MCP server that lets AI agents connect accounts, run campaigns, send messages and place calls autonomously, with detailed per-post and per-account analytics.
Pricing is usage-based: first 2 accounts free, then $6/account for 1-10, dropping to $3 and $1 as volume grows.

Why we picked it
Zernio solves a real pain every developer building multi-platform products faces: instead of juggling 17 different APIs and auth flows, you get one clean interface. The built-in MCP server makes it a natural fit for AI agents that need social reach.
