403 PERMISSION_DENIED — Request to review Gemini API access for haqibati-platform

Hello Google team,

Please help review Gemini API access for my project.

Project name: Haqibati Platform
Project ID: haqibati-platform
Project number: 4416491719..
Model: gemini-3.5-flash-lite
Billing tier: Free tier

My application’s generateContent requests return:
HTTP 403 / PERMISSION_DENIED
“Your project has been denied access. Please contact support.”

I have confirmed that:

  • My Google Account age is verified.

  • My phone number ownership is verified.

  • 2-Step Verification is enabled, and a subsequent request still returned the same error.

  • AI Studio displays Free tier, with no visible restriction notice.

  • The Google Cloud dashboard shows no visible suspension banner.

The application uses server-side requests from Cloudflare Pages Functions to validate Arabic training-program titles and generate training outlines.

I would like to remain on the Free tier. Could you identify the reason for the access restriction and advise how to request a manual review or restore access if eligible?

If this forum cannot handle the review, please direct me to the appropriate support or appeal channel.

Thank you.
