}Frequently Asked Questions — X (Twitter)
Can I publish to X (Twitter) without paying $200/month for the X Basic API tier?
Yes. By connecting X in Reeling Companion mode and keeping the Reeling Companion extension active in Chrome, Reeling dispatches your posts through your logged-in x.com browser session at $0 API cost.
Does X Companion mode work with remote AI agents (OpenClaw, Claude, Cursor)?
Yes. Remote MCP and REST API calls queue the post on Reeling’s backend, and your open Chrome browser’s Reeling Companion picks it up within ~3 seconds and publishes it live on x.com.
