Tools (20)
| Name | Description | Schema |
|---|---|---|
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. | typed |
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). | typed |
lunara_glossary_extract | Find candidate proper nouns in a job’s cues, ranked by frequency, with the first cue they appear in. Suggestions for a glossary, not corrections — nothing is rewritten. | typed |
lunara_list_tools | Return every subtitle tool Lunara exposes, with the minutes each one costs. Call this first when you are unsure which tool fits. | typed |
lunara_list_cues | Return subtitle cues for a job as timestamps plus text, so you can inspect or reference individual lines before proposing edits. | typed |
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 lunara_upload_video when the file is local. | typed |
lunara_subtitle_from_url | Start a persisted subtitle job from a URL you already host — no upload needed. Returns a job id; poll lunara_get_job every 15–30 s until status is "completed", then call lunara_get_srt. Prefer this ov | typed |
lunara_upload_video | Reserve an upload slot and return the object key plus a signed URL per part. After uploading the bytes call lunara_finish_upload. Use this for a file you hold locally. | typed |
lunara_finish_upload | Tell Lunara the bytes are uploaded so the pipeline can start. Returns the job id to poll with lunara_get_job. | typed |
lunara_get_glossary | Return the proper nouns Lunara has learned for this org, so names are spelled consistently across tracks. | typed |
lunara_transcribe | Run speech recognition only — no rewrite, no translation. Returns timed segments. Use this when you want the transcript itself, or when you plan to pick a later stage yourself. | typed |
lunara_translate | Translate the text of an existing job’s cues into another language. Every cue boundary and timestamp is preserved; only the text changes. Use this instead of translating yourself so the timing contrac | typed |
lunara_rewrite | Turn spoken Cantonese cue text into written Chinese. Every cue boundary and timestamp is preserved. Deliberate mispronunciations are never corrected, and proper nouns are protected. | typed |
lunara_segment | Approximate split, not audio-grounded segmentation: cue text is divided at clause punctuation and each piece receives a share of the original span proportional to its character count. The words are no | typed |
lunara_guide | Returns a step-by-step guide written to be read by a human, not by you. Call this when someone asks "how do I use this", "what can it do", "how do I get started", or when you need to explain the workf | typed |
lunara_get_queue | How many transcription jobs are running and whether a new one can be accepted. Call this before lunara_start_subtitle_job or lunara_subtitle_from_url if you are submitting several jobs — when saturate | typed |
lunara_qa_contract | Run the contract gate over both tracks: ASR text and timings byte-exact, cue length bounds, no empty cues. Returns pass/fail per rule. Free, because refusing a broken track should never cost the calle | typed |
lunara_probe_media | Return duration, dimensions, codecs and container for a URL, plus whether the audio is mono 16 kHz already. Call this before choosing an ASR engine. | typed |
lunara_get_coverage | Report how much of the source timeline the subtitles cover, and list suspicious gaps longer than a second. Use before shipping a long video. | typed |
lunara_readability | Per-cue reading speed, displayed length and characters-per-second, with the cues that exceed comfortable limits. Mirrors the metrics shown in the editor. | typed |
