Every completed moderation job reports is_prohibited as a boolean. While the job is still processing, is_prohibited is null.

​
Decision rule

The logic is straightforward:
  • is_prohibited: false — all categories (built-in and custom) are false.
  • is_prohibited: true — any category is true.
There is no confidence score or threshold — the decision is binary based on category detection.

​
Example: partial rejection

In this example, only nsfw is triggered. is_prohibited is true even though all other categories are false.

​
Image-moderation specifics

  • The result reflects the combined output of all VLM child jobs and any custom-category checks.
  • Keyword matches can set specific categories. For example, blocked keywords related to minors set underage: true.

​
Prompt-moderation specifics

  • Prompt-only jobs evaluate no built-in categories. The categories field is omitted entirely from the response for prompt jobs.
  • is_prohibited is true when the LLM prohibition check judges the prompt prohibited; reason (top-level) explains why. Otherwise is_prohibited is false.

​
Video-moderation specifics

  • Categories are merged across all extracted frames using OR logic. If any single frame triggers a category, that category is true for the entire video.

​
Underage detection

When the underage category is true, is_prohibited is true like any other category violation. Repeated underage detections may be reviewed manually and can result in account termination at our discretion — see account termination.
