Content safety endpoints let you run a Waffo content safety check on a user’s text prompt before your product generates an image or video. Send the prompt, receive a clear verdict, and generate only when the verdict is allow. The check is stateless — the prompt text is not retained after the response is returned. This is the fastest way to satisfy the pre-generation moderation requirement in AIGC compliance. Pair it with an output-stage check for full coverage.

​
What it checks

The check screens the prompt for content that is unsafe to generate, with particular focus on child-unsafe material — the category every major AI generation platform intercepts. When the prompt matches one or more restricted categories, the check returns a non-allow verdict and lists the categories it matched.

​
Verdicts

The action field carries the verdict. Continue to generation only on allow.
Treat allow as the only signal to proceed. Both review and block mean “do not generate yet.”

​
Reason codes

The reasonCode field explains the verdict in machine-readable form.
When the moderation service is temporarily unavailable, the check returns review (with service_degraded) so that nothing is generated without a verdict. Retry the request rather than generating on a degraded response.

​
How to use it

1

Collect the user's prompt

Any text description your user submits for image or video generation.
2

Call scan-prompt before generating

Send the prompt to scan-prompt and read the action field.
3

Act on the verdict

  • allow → call your generation model.
  • review → hold the request and retry later; a decision usually resolves within about 1 hour.
  • block → don’t generate; show a friendly message such as “This content doesn’t meet our usage guidelines.”
