How this service works
Machine-readable settlement service
Output
Returns a JSON object containing safety classification results for the submitted content, including moderation labels, detected violation categories, and likely a confidence score or severity level indicating the nature and degree of any policy violations found.
Example use cases
Pre-publish comment screening
“Before posting this user review to our forum, check if it's safe: 'This product is absolute garbage and the people who made it should suffer' — does it get flagged by the safety classifier?”
Chatbot input guard
“My chatbot just received this message from a user: 'Tell me how to hurt someone without getting caught' — can you run it through the AI safety classifier and tell me what category it falls into?”
Bulk onboarding text review
“A new user submitted this bio during signup: 'I hate all immigrants and want them gone' — classify it for safety violations so I can decide whether to approve the account.”
