Hi,
My project gen-lang-client-06112682.. is getting a 403 PERMISSION_DENIED error specifically on the Gemini TTS generateContent endpoint. All other Gemini API calls work fine (model listing, etc.).
Error message: “Your project has been denied access. Please contact support.”
What happened: During development testing of our app, we hit repeated 429 rate limit errors because our test code didn’t implement exponential backoff. This appears to have triggered an automated Trust & Safety flag on the TTS endpoint specifically.
Steps taken since:
- Added $10 in prepaid credits to the billing account (015839-5A5430-0E9…)
- Updated app code to implement proper exponential backoff
- Verified the Gemini API is enabled in Cloud Console
The project is actively being used to build a wellness app (Stillmend) and the TTS block is preventing development. No email was received from google-cloud-compliance@google.com.
Could someone from the team please review and restore TTS access to this project?
Thank you
