Gemini API Access Denied Across Two Projects – Request for Manual Review

Hello Google Gemini API Team,

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

Every Gemini API content-generation request returns:

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

I have already completed the recommended account checks:

  • Age information is valid
  • Phone number is verified
  • 2-Step Verification is enabled
  • I am using a personal Google account
  • I created a new Google Cloud project
  • I created a new Gemini API key
  • The same 403 error occurs on both the original and the new project
  • Google AI Studio shows the billing/access tier as “Unavailable”

Intended use: personal academic research and Fiji/ImageJ bioimage analysis.

I would like to remain on the Free Tier if possible.
Could you please manually review my account/project access and restore Gemini API access if this restriction was applied in error?

I have not included any API keys or private credentials in this post.

Thank you.
