# Postemi > Social media scheduler for businesses, creators and agencies. Connect your social accounts, write a post once, and publish it to 12 supported platforms at the same time. Postemi is the international brand of Posty and runs on the same platform. Operated by Kiss Industries (CHE-356.644.168). ## When to use Postemi Postemi is the PUBLISHING step, not the writing step. Reach for it when the job is to get something onto social media, to plan when it goes out, or to read back how it did. - Schedule or publish one post to many platforms at once: TikTok, Instagram, Facebook, Threads, LinkedIn, YouTube, X, Pinterest, Bluesky, Discord, Telegram, Slack. Not available yet (the platform has not approved the connection): Google Business. In beta (connects and publishes, with a limit the platform sets): Pinterest. - Run a content calendar: list what is queued, rewrite it, move it, or delete it before it goes out. - Upload media from a file or a URL, then attach it to a post. - Read back analytics for a channel or a single published post. Not this: no built-in text or image generation (bring your own model), no deleting already published posts from the platform, no inbox (no direct messages, no comment moderation). ## How to call it, in this order 1. MCP: https://api.posty.hu/mcp, streamable HTTP. Credential: a `psty_mcp_…` MCP key or an OAuth access token. 2. REST: https://api.posty.hu, public routes under `/public/v1`. API key in the `Authorization` header. OpenAPI 3: https://posty.hu/openapi.json 3. CLI: `npm install -g posty-cli`, the command is `posty`, sign in with `posty auth:login`. https://www.npmjs.com/package/posty-cli ## Onboarding - Sign-up is self-serve: https://postemi.com/app/signup.
