Zernio

Data & Agents

One social media API for 15 platforms, built for AI agents.

What it’s for

Zernio replaces a dozen separate platform integrations with a single REST API for publishing, scheduling, DMs, comments, analytics and ads across Instagram, TikTok, X, LinkedIn, YouTube and more. It handles OAuth, media formatting and rate limits for you, and ships a hosted MCP server with 280+ tools so agents can run your social accounts.

How to use it

Sign up for an API key, connect your social accounts through the hosted OAuth flow, then publish to several platforms with one POST /posts call. To use it from an agent, add the MCP server to Claude, Cursor or any MCP client.

Pricing

Free for the first 2 connected accounts with full features. After that, usage-based per account: $6 for accounts 3-10, $3 for 11-100, $1 for 101-2,000 per month.
