## Response `200`

Current status for the requested job

- TranslateCaptionsJobResponseV0
  - `data` TranslateCaptionsJobV0, required
    - `id` string, required: Unique job identifier.
    - `passthrough` string: Arbitrary string supplied at creation, returned as-is.
    - `units_consumed` integer, required: Number of Mux AI units consumed by this job.
    - `directive` JobDirectiveContextV0: The directive run that dispatched this job. Absent for jobs created via direct API POST.
      - `id` string, required: ID of the directive that dispatched this job.
      - `run_id` string, required: ID of the specific directive run that dispatched this job.
    - `created_at` integer, required: Unix timestamp (seconds) when the job was created.
    - `updated_at` integer, required: Unix timestamp (seconds) of the job's last state transition (e.g. when it started processing or reached a terminal state).
    - `workflow` 'translate-captions', required
    - `parameters` TranslateCaptionsJobParametersV0, required
      - `asset_id` string, required: The Mux asset ID of the video whose captions will be translated.
      - `track_id` string, required: The Mux text track ID of the source caption track to translate. The asset must have a ready text track matching this ID or the request will be rejected.
      - `to_language_code` string, required: BCP 47 language code for the translated output (e.g. "es", "ja"). Unless replace_existing_tracks allows replacement, the asset must not already have a text track for this language.
      - `track_name` string: Name for the translated Mux text track. Defaults to "{Language} (Auto-translated)", e.g. "Spanish (Auto-translated)". Mux requires text track names to be unique on an asset, and an existing track with this name is handled according to `replace_existing_tracks`.
      - `upload_to_mux` boolean: Whether to upload the translated VTT and attach it as a text track on the Mux asset. Defaults to true.
      - `never_translate` string[]: Best-effort list of terms (brand names, proper nouns) to preserve verbatim in the translated captions. Does not guarantee exact output. Terms must not contain '<' or '>', invisible characters, or characters altered by Unicode normalization.
      - `replace_existing_tracks` 'fail' | 'replace_all' | 'replace_generated': What to do when the asset already has a text track in the same language as, or with the same name as, the translated track. Defaults to `fail`, which rejects the request before any translation is billed. `replace_all` deletes every such track first. `replace_generated` deletes only Mux Video auto-generated tracks and rejects if an uploaded track is in the way. Any value other than `fail` requires `upload_to_mux` to be true. Existing tracks are matched by language ignoring region subtags, and by name ignoring case, in any status.
    - `status` 'pending' | 'processing' | 'completed' | 'errored' | 'cancelled', required: Current job status.
    - `errors` JobErrorV0[]: Error details. Present when status is 'errored'.
      - `type` string, required: Stable public error category identifier.
      - `message` string, required: Human-readable public error message.
      - `retryable` boolean: Whether retrying this job may resolve the error.
    - `resources` ResourcesV0: Related Mux resources linked to this job.
      - `assets` SlimlineAssetV0[], required: Mux assets associated with this job.
        - `id` string, required: Mux asset ID.
        - `meta` object: Mux asset metadata, if available.
          - `title` string: Asset title from Mux metadata.
          - `creator_id` string: Creator identifier from Mux metadata.
          - `external_id` string: External identifier from Mux metadata.
        - `passthrough` string: Passthrough string from the Mux asset.
        - `_links` object, required: Hypermedia links for the asset.
          - `self` object, required
            - `href` string, required: URL to the Mux asset resource.
    - `outputs` TranslateCaptionsJobOutputsV0: Workflow results. Present when status is 'completed'.
      - `uploaded_track_id` string: Mux text track ID of the uploaded translated captions. Present when upload_to_mux is true.
      - `temporary_vtt_url` string: Temporary pre-signed URL to download the translated VTT file, including when upload_to_mux is false. Expires 7 days after the job completes.
      - `never_translate_terms_preserved` boolean: Present when never_translate terms were supplied. False when at least one term was not preserved verbatim in the translated captions. Preservation is best-effort: verified, not guaranteed.
      - `replaced_tracks` ReplacedTrackV0[]: Every track deleted before the new track was created. Present when `replace_existing_tracks` was a deleting policy and at least one track was removed.
        - `id` string, required: Mux track ID of the deleted track.
        - `type` 'text' | 'audio': Mux track type of the deleted track.
        - `name` string: Name of the deleted track.
        - `language_code` string: Language code of the deleted track.
        - `text_source` string: Mux `text_source` of the deleted track, e.g. `uploaded` or `generated_vod`. Absent for audio tracks.
        - `passthrough` string: `passthrough` value the deleted track carried, if any.
