Let your AI agent post your videos

If a script or AI agent makes your videos, the last step shouldn't be you dragging files into three apps. Postline has a plain HTTP API, and a ready-made prompt you can paste into your agent.

The easy way

  • Make an API key in Settings.
  • Click Copy prompt for my agent and paste it into Claude Code, Cursor or any agent that can run commands.
  • The agent lists your channels, asks which videos to send, uploads them and queues them, or posts straight away and gives you the links.

The API

  • GET /channels lists your channels and platforms.
  • POST /uploads returns a signed link, and you PUT the file to it.
  • POST /videos queues it with a title and caption, or posts it now.
  • GET /videos/<id> returns the status and a link per platform.

Good to know

A key can add and post videos on every channel in its workspace, so keep it private. Your workspace needs video storage connected first.
