Gemini API returns 403 even for a minimal text request — access review requested

Hello Google team,

I am developing a small video-game inventory application in Portugal and cannot use the Gemini API.

Project ID: [vintedapp-509611]
Model: gemini-3.6-flash
Test date: 24 September 2026
Environment: Python, Google Gen AI SDK, macOS

Even a minimal text-only generate_content request asking “Reply only OK” returns:

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

This test does not use any scraped content, images or files.

I generated a replacement API key through AI Studio and verified that the application loads the configured key. The error persists. I do not see a restriction banner on the Cloud Console welcome page.

Could you review the project’s Gemini API access and explain what action is required? I can provide further details through a private support channel.

Thank you.
