Gemini API returns 403 “Your project has been denied access” on Free Tier project

Hello Google Gemini API Team,

I am a university student working on a non-commercial academic research-agent project.

My Gemini API requests consistently return:

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

Project:

  • Project name: analyst-auditor

  • Project ID: gen-lang-client-01832668..

  • Billing tier: Free Tier

I have already completed:

  • Created a Gemini API key for the project

  • Enabled 2-Step Verification

  • Confirmed the API key loads correctly in Python

  • Tested the official Google GenAI Python SDK

  • Tested directly with gemini-3.6-flash

  • Created/tested a new API key

  • Confirmed that the project is imported into Google AI Studio

The API request reaches Google successfully, but every generateContent request is rejected with HTTP 403.

My intended use is low-volume development and testing for a university project. I would like to remain on the Free Tier if possible.

Could you please manually review the Gemini API access status of this project/account and let me know whether the restriction can be removed?

I have not included my API key or any other private credentials.

Thank you.
