create_clips
Start finding and rendering short vertical clips from a video. Give either source_id (from list_sources) or youtube_url. This costs one token per clip, so ask the user how many they want if they have not said, and set clip_count to that number. It returns a job_id immediately — rendering takes several minutes — then poll check_job.

get_account
The signed-in Keptbits account: its plan and what that plan allows. Check this before starting a run, so the run asks for something the account can actually have.
