No simple toggle to switch Claude Code between Pro and API billing?

Spent way more time than I should have switching Claude Code (Anthropic's coding agent) from API-key billing back to my Pro subscription. The flow: SSH into a server, attach a tmux session, run a login command, copy an OAuth URL, open a browser, authorize, paste the code back into the terminal.

For a company shipping frontier AI models, this feels like UX that was solved a decade ago. A single command or flag to switch billing mode would save a lot of friction.

Curious if other AI coding tools handle this better, or if this is standard across the industry.
