403 PERMISSION_DENIED – Gemini API project is Restricted

Hello Google Gemini API Team,

I am experiencing an access restriction on my Gemini API project.

Google AI Studio currently shows:

Billing Tier: Unavailable
Status: Restricted

Every Gemini API request returns:

403 PERMISSION_DENIED
“Your project has been denied access. Please contact support.”

I have completed phone verification and 2-Step Verification.

I am trying to use the Gemini API for a small personal/student development project. I only need the Free Tier and do not want to enable paid billing.

Could you please manually review the project and restore Free Tier API access if this restriction is a false positive?

Thank you.
