🟢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.

  "properties": {},
  "additionalProperties": false
}
🟢lunara_get_job(jobId)

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.

入力スキーマ

{
  "type": "object",
  "properties": {
    "jobId": {
      "type": "string",
      "description": "The job id returned by lunara_upload_video."

  },
  "required": [
    "jobId"
  ],

🟢lunara_get_srt(jobId, track)

🟢lunara_list_cues(jobId, offset, limit)

🟡lunara_start_subtitle_job(audioUrl, primaryLang, secondaryLang, spokenLang)

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.

  ],
  "additionalProperties": false
}
🟡lunara_subtitle_from_url(audioUrl, filename, primaryLang, secondaryLang, spokenLang)

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 over lunara_upload_video whenever the media is reachable by URL.

}
🟡lunara_upload_video(projectId, clientOperationId, filename, mime, sizeBytes, ...)

🟡lunara_finish_upload(videoId, uploadId, key, durationMs, parts)

Tell Lunara the bytes are uploaded so the pipeline can start. Returns the job id to poll with lunara_get_job.

    "parts"
  ],
  "additionalProperties": false

🟢lunara_get_glossary(limit)

Return the proper nouns Lunara has learned for this org, so names are spelled consistently across tracks.

入力スキーマ

{
  "type": "object",
  "properties": {
    "limit": {
      "type": "integer",
      "minimum": 1,
      "maximum": 500,
      "description": "Default 100."
    }
  },
  "additionalProperties": false
}
⚪lunara_transcribe(audioUrl, spokenLang)

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.

入力スキーマ

{
  "type": "object",
  "properties": {
    "audioUrl": {
      "type": "string",
      "description": "Direct HTTP(S) URL to the audio or video file."

    }
  },
  "required": [
    "audioUrl"
  ],
  "additionalProperties": false
}
⚪lunara_translate(jobId, targetLang, track)

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 contract holds.

入力スキーマ

{
  "type": "object",
  "properties": {
    "jobId": {
      "type": "string",
      "description": "The job whose cues to translate."

        "secondary"
      ],
      "description": "Which track to read. Default primary."
    }
  },
  "required": [
    "jobId",
    "targetLang"
  ],
  "additionalProperties": false
}
⚪lunara_rewrite(jobId, track)

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.

入力スキーマ

{
  "type": "object",
  "properties": {
    "jobId": {
      "type": "string",
      "description": "The job whose cues to rewrite."

        "primary",
        "secondary"

      "description": "Which track to read. Default primary."
    }
  },
  "required": [
    "jobId"
  ],
  "additionalProperties": false
}
⚪lunara_segment(jobId, maxCueMs, track)

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 not changed. Timings are estimated, so treat them as a reading aid rather than a re-alignment — use lunara_start_subtitle_job if you need timing derived from the audio.

入力スキーマ

{
  "type": "object",
  "properties": {
    "jobId": {
      "type": "string",
      "description": "The job whose cues to re-cut."

      "enum": [
        "primary",
        "secondary"
      ],
      "description": "Which track to read. Default primary."
    }
  },
  "required": [
    "jobId"
  ],
  "additionalProperties": false
}
🟢lunara_glossary_extract(jobId, limit)

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.

入力スキーマ

{
  "type": "object",
  "properties": {
    "jobId": {
      "type": "string",
      "description": "The job whose cues to scan."

    "limit": {
      "type": "integer",
      "minimum": 1,
      "maximum": 200,
      "description": "Maximum terms to return. Default 50."
    }
  },
  "required": [
    "jobId"
  ],
  "additionalProperties": false
}
🟢lunara_qa_contract(jobId, track)

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 caller money.

入力スキーマ

{
  "type": "object",
  "properties": {
    "jobId": {
      "type": "string",
      "description": "The job to validate."
    },
    "track": {
      "type": "string",
      "enum": [
        "primary",
        "secondary",
        "both"
      ],
      "description": "Which track to check. Default both."
    }
  },
  "required": [
    "jobId"
  ],
  "additionalProperties": false
}
🟢lunara_probe_media(mediaUrl)

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.

入力スキーマ

{
  "type": "object",
  "properties": {
    "mediaUrl": {
      "type": "string",
      "description": "URL to probe."
    }
  },
  "required": [
    "mediaUrl"
  ],
  "additionalProperties": false
}
🟢lunara_get_coverage(jobId)

Report how much of the source timeline the subtitles cover, and list suspicious gaps longer than a second. Use before shipping a long video.

入力スキーマ

{
  "type": "object",
  "properties": {
    "jobId": {
      "type": "string",
      "description": "The job to inspect."
    }
  },
  "required": [
    "jobId"
  ],
  "additionalProperties": false
}
🟢lunara_readability(jobId, track)

Per-cue reading speed, displayed length and characters-per-second, with the cues that exceed comfortable limits. Mirrors the metrics shown in the editor.

入力スキーマ

{
  "type": "object",
  "properties": {
    "jobId": {
      "type": "string",
      "description": "The job to measure."
    },
    "track": {
      "type": "string",
      "enum": [
        "primary",
        "secondary"
      ],
      "description": "Default primary."
    }
