Is there a CLI or SDK?

Yes. The CLI is @posteverywhere/cli on npm, and the Node.js SDK is @posteverywhere/sdk. Both use the same API, so an account connected once works everywhere.

CLI: log in and post#

1. Run npx @posteverywhere/cli login. Your browser opens app.posteverywhere.ai/device.
2. On the Connect your CLI page, enter the code the terminal shows and click Authorize device. The page then says Device authorized.
3. The CLI saves a key in ~/.posteverywhere/config.json. You can see and revoke it on the Developers page, API Keys tab.
4. Try it:

posteverywhere accounts
posteverywhere post -c "Hello" -a 123,456

For a server or CI, skip login and set POSTEVERYWHERE_API_KEY=pe_live_... instead.

CLI commands#

Command	What it does
login / logout	Log in with a browser code; remove the saved key
whoami	Your account, plan and remaining quota
accounts	Connected accounts with ids and health
platform-rules [platform]	Character limits, media rules and supported features
connect	Connect your coding agents to the MCP server
connect <platform>	Connect a new social account
reconnect <accountId>	Reconnect an account whose login expired
account:health <id>	Why one account cannot post
post -c <text> -a <ids> [-s <iso>] [-m <mediaIds>]	Publish now, or schedule with -s
post -a <ids> --title <t> --body-file <md>	WordPress blog post
posts	List posts, filter by status and platform
results <postId>	Per-platform success or failure
retry <postId>	Retry the failed destinations
upload <url>	Import an image or MP4 by link
caption -t <topic>	AI captions per platform
analytics [--period]	Performance summary
campaigns	List campaigns

Add --json for machine-readable output. It turns on by itself when the output is piped.

Node.js SDK#

npm install @posteverywhere/sdk

import PostEverywhere from '@posteverywhere/sdk';

const client = new PostEverywhere({ apiKey: process.env.POSTEVERYWHERE_API_KEY });
const { accounts } = await client.accounts.list();
await client.posts.create({ content: 'Posted from code', publish_now: true });

Typed errors carry a retryable flag, and the SDK supports idempotency keys. Full docs on the npm page and at posteverywhere.ai/docs.

Which one?#

• An agent that runs shell commands (Claude Code, Codex, Cursor): the CLI, plus npx skills add posteverywhere/cli.
• An agent that speaks MCP (Claude, ChatGPT, hosted agents): the Agents page.
• Your own application: the SDK or the REST API.
