Request for Manual Review: 403 PERMISSION_DENIED and "Unavailable" Across Multiple Gemini API Projects

Hello Gemini API Team,

I am experiencing an unexpected Gemini API access restriction affecting multiple projects across two separate Google accounts.

Affected projects:

Google Account 1:

  • astrbot-gemini-502002
  • gen-lang-client-0848688205

Google Account 2:

  • gen-lang-client-0738183760

The affected projects are currently shown as “Unavailable” in Google AI Studio.

For the affected projects I tested, Gemini API requests return:

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

These projects previously worked normally, but the restriction appeared unexpectedly.

I also checked the affected projects in Google Cloud Console. I could not find any warning banner, policy violation notice, suspension reason, or “Request an appeal” option explaining why access was denied.

I have already submitted GCP Account Suspension Inquiry requests through the Google Cloud support troubleshooter, but I am also posting here because the same issue is affecting multiple projects across two separate Google accounts.

Could someone from the Gemini API team please review this issue or help route it to the appropriate team for manual review?

If these restrictions were applied in error, I would appreciate restoration of Gemini API access.

I can provide additional project information, screenshots, error logs, or support tracking numbers if needed.

Thank you.
