Gemini Project and Key Restricted

Hello Google AI Studio team,

My Google AI Studio projects are showing:

Status: Restricted

Billing Tier: Unavailable

The interface says: “This Project’s API access is restricted. Please set up billing to continue.”

I have completed 2-Step Verification, and my intended use is legitimate website development and testing for school.

Could someone please review my account/project and let me know why Free Tier API access is restricted and whether it can be restored?

Thank you.
