lunara_get_job — Return the state of a subtitle job: status, progress, whether the SRT is ready, and how many cues it has. Poll this after lunara_upload_video.
lunara_get_srt — Return the subtitle file for a finished job. One line per cue. Use track="secondary" for the translated track (English by default).
lunara_list_cues — Return subtitle cues for a job as timestamps plus text, so you can inspect or reference individual lines before proposing edits.
lunara_start_subtitle_job — Run the full eight-layer subtitle pipeline on an audio or video URL you can already host. Produces a written-language track and a translated track. Prefer lunar
