Gemini API 403 Permission Denied – Request for Project Access Review

Hello Gemini API Team,

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

My Google AI Studio project is:

Project name: Default Gemini Project
Project ID: gen-lang-client-05350813..

The billing tier is shown as unavailable, and when my application
calls the Gemini API, I receive:

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

I am developing a low-volume academic college project called
“AI Interview Platform” for development, testing, and demonstration.

The application uses Gemini to generate interview questions from
a student’s resume and evaluate interview answers.

I have updated the application to use gemini-3.8-flash, but the API
request is still rejected with the project-level 403 error.

I would like to use the Gemini API Free Tier for this educational
project and would prefer not to enable paid billing solely to
bypass this restriction.

Could you please review my project/account and restore Gemini API
access if the restriction was applied in error?

I have not included any API keys, passwords, or private credentials.

Thank you.
