Manual review request — Gemini Files API upload returns 403 PERMISSION_DENIED

Gemini API
1

Hello Google AI Team,

I am requesting a manual review of an unexpected Gemini API project restriction.

Error

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

Project details

  • Project name: My-Gemini-App
  • Project ID: my-gemini-app-5054..
  • Project number: 6095614993..
  • Billing tier: Unavailable
  • Billing account: None (free-tier project)

What I verified

  • The API key was created in Google AI Studio and is restricted to the Gemini API.
  • Model metadata access works.
  • GET /v1beta/files?pageSize=1 returns HTTP 200.
  • Gemini Files API video upload consistently returns HTTP 403.
  • The same failure occurs through the official Google Gen AI JavaScript SDK.
  • The key is stored only in a backend environment variable and is not exposed in the frontend.
  • No restriction or appeal banner is visible in Google Cloud Console or Google AI Studio.
  • Cloud Billing Support cannot assist because this free-tier project has no billing account.

Use case

This project is an internal AI short-video quality-control system. Gemini is used only to review uploaded video content quality, including opening-hook quality, product visibility, selling-point clarity, pacing, subtitle/audio clarity, visual quality, and compliance risks.

Please check whether the project or account was incorrectly flagged by an automated security review and restore Gemini Files API upload access, or provide the appropriate free-tier appeal channel.

Thank you.
