What You Can Do

• Schedule posts to multiple platforms simultaneously
• Customize content per platform (hashtags, titles, privacy settings)
• Save drafts with draft: true, review them, then schedule with POST /v1/posts/{id}/schedule — ideal for human-in-the-loop agent workflows
• Upload media (images and video) with automatic processing
• Schedule many posts by calling Create Post in a loop with different scheduled_for times
• Monitor results with per-platform publishing status
• Retry failed posts automatically or on demand
• Generate AI images from text prompts

SDKs & Tools

Node.js SDK

npm install @posteverywhere/sdk

import { PostEverywhere } from '@posteverywhere/sdk';

const client = new PostEverywhere({ apiKey: 'pe_live_...' });

const post = await client.posts.create({
  content: 'Hello from the API!',
  account_ids: [123, 456, 789],
  scheduled_for: '2026-04-01T10:00:00Z',
});

Command line (CLI)

Log in, connect every platform, and publish straight from your terminal:

npm install -g @posteverywhere/cli
posteverywhere login                 # browser approve, key saved locally
posteverywhere connect instagram     # OAuth opens; the account is auto-detected
posteverywhere post -c "Hello from the CLI!" -a 123,456

Every command supports --json for AI agents. Full guide: CLI.

Claude Code (MCP)

Easiest — connect to the hosted endpoint, nothing to install:

claude mcp add --transport http posteverywhere \
  https://mcp.posteverywhere.ai \
  --header "Authorization: Bearer pe_live_YOUR_KEY"

Or run it locally via npx:

{
  "mcpServers": {
    "posteverywhere": {
      "command": "npx",
      "args": ["-y", "@posteverywhere/mcp"],
      "env": { "POSTEVERYWHERE_API_KEY": "pe_live_..." }
    }
  }
}
