Request for Manual Review — Gemini API Free Tier — 403 PERMISSION_DENIED — Project Quota Tier Unavailable

Hello Google Gemini API team,

I am requesting a manual review of my Gemini API project access.

I am trying to use the Gemini API on the Free Tier for local development of my application, MIFA AI.

Project:
My First Project

Current Google AI Studio status:

  • Project quota tier: Unavailable
  • Billing tier: Unavailable
  • API access: Restricted

My application receives:

HTTP 403 Forbidden

Request endpoint:
https://generativelanguage.googleapis.com/v1beta/models/gemini-3.8-flash:streamGenerateContent?alt=sse

Model:
gemini-3.8-flash

The API key was newly created in Google AI Studio and is an Authorization API key.

The request uses the official Gemini API authentication header:
x-goog-api-key

The API key itself is NOT included in this post.

I have already completed the account verification requirements:

  • 2-Step Verification is enabled
  • Phone number verification is complete
  • Age / date-of-birth verification is complete

Despite these being completed, Google AI Studio continues to show:

“Project quota tier unavailable. Please contact your project administrator for assistance.”

API requests continue to return HTTP 403 PERMISSION_DENIED.

I am requesting access to the Gemini API Free Tier for legitimate low-volume local development and testing.

I am NOT requesting a paid-tier upgrade, and I do not want to enable paid billing or prepayment.

Could you please manually review the account/project restriction and let me know whether this project can be granted Free Tier Gemini API access?

If there is a specific requirement or restriction that is preventing Free Tier access, please tell me what needs to be completed.

Thank you.
