Hello,
I am trying to use the Gemini API Free Tier with my personal Google account.
However, my project is marked as “Restricted” in Google AI Studio, and I receive the following error when using the API:
403 PERMISSION_DENIED
“Your project has been denied access. Please contact support.”
I have tried both gemini-3.6-flash and gemini-3.5-flash-lite, but both return the same error.
Google AI Studio asks me to set up billing, but I would prefer to use the Free Tier without enabling paid billing.
Could you please help me understand why my project is restricted and whether I can restore Free Tier access?
Thank you for your help.
