Request for manual review — Gemini API 403 PERMISSION_DENIED / multiple projects Restricted

Hello Gemini API / Google AI Studio team,

I am requesting a manual review of Gemini API access for my Google account and projects.

Google AI Studio currently shows:

Billing tier: Unavailable
Status: Restricted

Gemini API content generation requests return:

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

I have already completed the recommended account verification steps:

Phone verification completed
2-Step Verification enabled
Account holder is over 18 / age verification completed
API key is valid
I created a completely new Google Cloud project, imported it into Google AI Studio, and the new project was immediately marked Restricted as well

This suggests that the restriction may be account-level rather than related to a specific API key or project.

My intended use is low-volume personal/academic PDF translation through Zotero PDF2zh. I am not using the API for scraping, bulk messaging, proxying, quota circumvention, or abusive automation.

Project 1 ID: unified-altar-508109…
Project 2 ID: commanding-iris-482509..

I would like to remain on the eligible Free Tier and would appreciate a manual review of the automated account/project restriction. If this restriction was applied in error, could you please restore Gemini API access?

I can provide additional account or project information privately if required.

Thank you.
