403 PERMISSION_DENIED — "Your project has been denied access" on new project

Gemini API
1

Hello,

I’m requesting a review and unlock of Gemini API access for the project below.
The error appears consistently, with no prior usage history and no known policy violation.

Project Number: 5080959952..
Account type: Personal Google account
Region: India

What I’ve verified:

  • Generative Language API is ENABLED
  • Billing shows as “Unavailable” when I try to set it up
  • No prior usage or policy violations

Error (occurs on every request, model gemini-2.5-flash, generateContent endpoint):
{“error”: {“code”: 403, “message”: “Your project has been denied access. Please contact support.”, “status”: “PERMISSION_DENIED”}}

Please advise on next steps to restore access.

Thank you.

Hello @yajath_nr,

Getting a 403 API error response and / or seeing “Unavailable” next to your project in AI audio indicates a flag has been placed on your account. To proceed:

  1. Check for banners / error callouts in the AI Studio Projects page & the Billing page.

  2. If the issue isn’t clear from the above, contact Cloud Billing Support.
