# Create a 'moderate' job

`POST /robots/v0/jobs/moderate`

## Request

- Base URL: `https://api.mux.com`
- URL: `https://api.mux.com/robots/v0/jobs/moderate`
- Auth: one of:
  - HTTP basic
  - HTTP bearer

> **Deprecated.**

Deprecated: use `POST /robots/v1/jobs/moderate` instead. Creates a new job that uses AI to analyze a Mux Video asset for inappropriate content. Optional output steering can restrict execution to a time scope in seconds.

## Request body

- CreateModerateJobRequestV0
  - `passthrough` string: Arbitrary string stored with the job and returned in responses. Useful for correlating jobs with your own systems.
  - `parameters` ModerateJobParametersV0, required
    - `asset_id` string, required: The Mux asset ID of the video to moderate.
    - `language_code` string: BCP 47 language code of the caption track to moderate. Used only for audio-only assets; ignored for video assets. When omitted, an English subtitles track is preferred and otherwise the first ready text track is used.
    - `thresholds` object: Score thresholds that determine whether content is flagged. When combined with sampling_interval or max_samples, the exceeds_threshold flag reflects whether any category's highest observed score exceeds its configured threshold. Defaults to {sexual: 0.7, violence: 0.8}.
      - `sexual` number: Score threshold for sexual content. Content scoring above this value triggers exceeds_threshold.
      - `violence` number: Score threshold for violent content. Content scoring above this value triggers exceeds_threshold.
    - `sampling_interval` integer: Interval, in seconds, between sampled thumbnails. Minimum 5 seconds. When max_samples is also set, the actual sampling density is the more restrictive of the two constraints.
    - `max_samples` integer: Maximum number of thumbnails to sample. Acts as a cap — if sampling_interval produces fewer samples than this limit, the interval is respected; otherwise samples are evenly distributed with first and last frames pinned.
    - `output_steering` ModerateOutputSteeringV0: Curated controls that optionally restrict moderation to an asset time range.
      - `scope` object: Optional execution window in seconds on the original asset timeline. Omit start_time to begin at the asset start and omit end_time to continue through the asset end. Moderation is restricted to media within this window, while returned timestamps remain absolute asset timestamps.
        - `start_time` number: Start of the execution window in seconds from the beginning of the media. When omitted, the window starts at the beginning.
        - `end_time` number: End of the execution window in seconds from the beginning of the media. When omitted, the window extends to the end.
    - `on_flagged` ActionOnFlaggedV0: Optional action taken automatically when exceeds_threshold is true. When omitted, the job only reports scores and takes no action. Note: in a directive run that targets the same asset with other workflows, deleting playback IDs can break sibling workflows that need a playback ID.
      - `action` 'delete_playback_ids', required: Action to take when exceeds_threshold is true. "delete_playback_ids" deletes every playback ID on the asset, making it unplayable while preserving the underlying asset so it can be re-published or reviewed.
