Request for Manual Review – Gemini API 403 PERMISSION_DENIED / Billing Tier Unavailable

Hello Google Gemini API Team,

I am requesting a manual review of Gemini API access for my Google Cloud project.

Project name: SellerAI
Project ID: sellerai-50811..
Region: Italy
Intended tier: Free Tier

Every generateContent request returns:
403 PERMISSION_DENIED
Your project has been denied access. Please contact support.

Google AI Studio shows:
Billing Tier: Unavailable

I have already completed:

  • Age verification
  • Phone verification
  • 2-Step Verification
  • Personal Google account
  • Google Cloud project created and imported into AI Studio
  • New Gemini API key created

I also verified the API key configuration in Google Cloud Console:

  • The API key is active
  • It is explicitly restricted to Gemini API
  • It is shown as bound to a service account

The intended use is a personal, low-volume application called SellerAI for analyzing photos of my own second-hand items and preparing marketplace listings.

I would like to remain on the Free Tier and I am not requesting a paid-tier upgrade.

Could you please manually review whether the project/account was restricted by an automated verification or risk-control system and restore Gemini API access if this restriction was applied in error?

Thank you.
