Hello Gemini API team,\n\nI am requesting a manual review of an unexpected access restriction affecting one project only.\n\nProject ID: social-studio-dating-tts\nProject number: 622187321793\n\nObserved behavior\n\n- GET /v1beta/models returns HTTP 200 and lists gemini-3.1-flash-tts-preview.\n- A minimal ordinary text generateContent request returns HTTP 403.\n- A minimal gemini-3.1-flash-tts-preview generateContent request returns the same HTTP 403.\n- Exact error: PERMISSION_DENIED — “Your project has been denied access. Please contact support.”\n\nFresh reproduction: 2026-08-14T09:26:27Z.\n\nThe Generative Language API is enabled. The project credential is accepted for model discovery, stored server-side, and restricted to the Gemini API. No API key is exposed in client code or included in this post.\n\nThe project initially passed access checks after setup, but generation was denied later. Google AI Studio now shows Status: Restricted and Billing Tier: Unavailable. The Cloud Console dashboard shows no explanatory warning, suspension banner, or appeal link.\n\nTroubleshooting completed\n\n- Confirmed the correct account and project.\n- Confirmed the Generative Language API is enabled.\n- Confirmed model discovery succeeds.\n- Reproduced the denial with both ordinary text generation and Gemini 3.1 Flash TTS Preview.\n- Tested minimal payloads at different times.\n- Checked AI Studio Projects and Billing pages and the Cloud Console dashboard.\n- Submitted AI Studio feedback on 2026-08-12, but it did not provide a trackable case number.\n\nLegitimate use case\n\nThis is low-volume, server-side TTS narration for operator-approved social media Motion Reels belonging to the project owner’s Dating Club TT brand. The generated audio is human-reviewed before publication. The API is not exposed to end users and is not used for scraping, credential sharing, resale, or unsolicited messaging.\n\nRequested action\n\nCould a Google team member please route project 6221873217.. for Gemini API access / Trust and Safety manual review?\n\nIf the restriction is a false positive, please restore generateContent access. Otherwise, please provide the specific actionable remediation or appeal path.\n\nNo credentials or API keys are included. I can provide sanitized request and response evidence if needed.\n\nThank you.
Hello @DatingClub_TT ,
Access to the free tier for this project is restricted by automated account verification checks.
To restore access, upgrade the project to a paid tier by setting up prepayment in Google AI Studio and/or attaching a Google Cloud Billing account in the Cloud Console.
Please try out the below steps:
-
- Complete Phone Verification and turn on 2-Step Verification (2SV) on the Google Account associated with your project.
- Once verified, retry your request or create a new API key in Google AI Studio.
-
Upgrade to a Paid Tier:
- If verifying your account does not restore access (or if using a model requiring a paid tier), you can unlock access by adding prepayment credits directly in Google AI Studio or attaching a Google Cloud Billing account in the Google Cloud Console.
