403 PERMISSION_DENIED "Your project has been denied access" on a brand-new project (220250346102)

Hi team, requesting a manual review of my account.

Every Gemini API call returns:

{"error":{"code":403,"message":"Your project has been denied access. Please contact support.","status":"PERMISSION_DENIED"}}

What I already ruled out:

• Happens on TEXT-only requests as well as image requests, on both gemini-3.6-flash and gemini-2.5-flash.
• Happens with a brand-new API key created today in a project that had never used the Gemini API before: project number 220250346102 / project id um-click-reviews.
• The Generative Language API shows “enabled” on that project.
• The key was generated in AI Studio and is correctly restricted to the Gemini API (not an unrestricted key).
• An older key from a different project on the same account returns the same error, so it does not look project-specific.
• AI Studio itself loads normally, with no pending Terms of Service prompt.
• Account located in Brazil (supported region).

Usage is a small business CRM for my home-automation company in Sao Paulo: it summarizes customer WhatsApp audio and reads photos and PDFs that customers send. Low volume, no scraping, no resale of the API.

Could you check what flagged the account and restore access? Happy to provide any other IDs.

Thanks.
