Integration

Zernio integration

Zernio (formerly Late) schedules and publishes social media posts across X, Instagram, Facebook, LinkedIn, TikTok, YouTube, Threads, Bluesky, Pinterest, Reddit, Telegram, Google Business Profile and more from one API. Create, schedule, publish, edit and unpublish posts, manage posting queues, profiles and connected accounts, read post and account analytics, answer comments, DMs, reviews and mentions in the unified inbox, and manage webhooks. Not exposed here: connecting new accounts (OAuth flows), media uploads (pass public HTTPS media URLs), ads, WhatsApp, SMS, voice and phone numbers, commerce, creator campaigns and payouts, broadcasts, sequences, contacts, calendar, files, blogs and API key management. Authentication is a Zernio API key sent as Authorization: Bearer <key>, created in the Zernio dashboard.

Connect Zernio How integrations work

Ask it in chat

Say what should happen.
The workflow builds itself.

When this happens, do that in Zernio.Built from the 87 Zernio tools below, on the connection you add once.

What you can do with Zernio

Each of these is one operation on one endpoint, available both as a workflow step and as a tool an AI agent can call on its own. Nothing bundles several operations into one action, so what a run did stays readable afterwards.

Each badge shows the default agent permission of an endpoint (allowed: an agent calls it without asking; ask first: you are asked before an agent calls it, when the agent or chat asks permission for sensitive actions; never: no agent may call it), which every user can change endpoint by endpoint in their credential settings.

Most endpoints run on the free plan. A few, mainly the ones that publish on your behalf, need a paid plan.

Use Zernio from Claude Code, Cursor or Codex

Connect Zernio in LiveContext, create an API key in Settings, then add the LiveContext MCP server to your client. Its Zernio operations become tools the client can call, next to every other integration you connected.

Claude Code

claude mcp add --transport http livecontext https://livecontext.ai/mcp --header "X-API-Key: YOUR_API_KEY"

Codex (~/.codex/config.toml)

[mcp_servers.livecontext]
url = "https://livecontext.ai/mcp"

[mcp_servers.livecontext.http_headers]
"X-API-Key" = "YOUR_API_KEY"

Cursor, Claude Desktop and other JSON configs

{
  "mcpServers": {
    "livecontext": {
      "type": "http",
      "url": "https://livecontext.ai/mcp",
      "headers": {
        "X-API-Key": "YOUR_API_KEY"
      }
    }
  }
}
