Free Tier Gemini API access restricted – 403 PERMISSION_DENIED

Hello Google Gemini API Team,

I am requesting a manual review of my Gemini API access.

My Google AI Studio project currently shows:

Billing Tier: Unavailable

The Rate Limit page shows:

Project quota tier unavailable.
This Project’s API access is restricted. Please set up billing to continue.

When I try to use the Gemini API from Python, I receive:

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

I have already completed phone verification and enabled 2-Step Verification.

My intended use is personal development and testing of a personal AI assistant.

I would like to remain on the Free Tier and do not want to enable paid billing.

Project ID: famous-robot-509905-..

Could you please review the restriction on my project/account and restore Gemini API Free Tier access if I am eligible?

I have not included my API key or any private credentials.

Thank you.
