Request for Manual Review: 403 PERMISSION_DENIED on Gemini API (Your project has been denied access)

Gemini API
1

Hello Gemini API Team / DevRel,

I am requesting a manual review and unblocking of Gemini API access for my personal Google Cloud Project.

I am trying to use the Gemini API (specifically the gemini-3.5-flash model within my n8n workflow) on the Free Tier, but all my API calls fail with the following error:
403 PERMISSION_DENIED: “Your project has been denied access. Please contact support.”

Project Details:

  • Project Number: 693233727..
  • Account Type: Personal Gmail Account (Non-Workspace)

I have verified the following:

  1. The Generative Language API is fully enabled in my Google Cloud Console.
  2. My Google account is a standard, personal Gmail account and is in good standing.
  3. Two-Step Verification (2SV) is active, and my phone number is fully verified on this Google Account.
  4. I am using the Free Tier and do not have an active billing account linked.

Since this block seems to be a false positive triggered by an automated risk classifier, could someone from the team please manually inspect my project and restore Gemini API access?

Thank you for your time and assistance!
