We are considering an adult-only web service in Japan that uses the paid Gemini Developer API to organize text written by users. Access would be via QR codes displayed in general retail and hospitality venues, which may also have customers under 18. The service would not be marketed to minors.
Before any questionnaire or text input, users would be required to affirm that they are 18 or older. Users who answer no or do not answer would be blocked. Our backend would reject AI requests without an adult-age declaration. No user account or identity-document verification is planned, and venue staff would not verify age. These are proposed controls, not a claim that they are already implemented.
Under the Age Requirements clause (https://ai.google.dev/gemini-api/terms):
- Would this adult-only service satisfy the restriction concerning API Clients likely to be accessed by individuals under 18, despite QR codes being visible in mixed-age venues?
- Is a required self-declaration of being 18 or older sufficient for this use case? If not, what additional verification or access controls are required?
- Is there official documentation or a private support channel where we can obtain clarification for this specific setup?
We are asking about the Gemini Developer API, not the consumer Gemini app or Vertex AI. We would appreciate clarification from an authorized Google representative.
