Project denied access — 403 PERMISSION_DENIED, even after creating a new project

Gemini API
1

Hello,

I’m requesting help restoring access to the Gemini API. All requests from my project are being rejected with the following error:

403 PERMISSION_DENIED: {“error”: {“code”: 403, “message”: “Your project has been denied access. Please contact support.”, “status”: “PERMISSION_DENIED”}}

Details:

  • This is a brand new project (created within the last few days) — this is not a case of a previously-working project suddenly breaking.
  • Project ID: gen-lang-client-06403171..
  • I generated a new API key under this project (via Google AI Studio) and it fails with the same 403 error.
  • I also attempted to create a second, separate Google Cloud project via Google AI Studio to work around this, but the project creation itself was rejected with: “Failed to create project, The request is suspicious. Please try again.”
  • I am the Google Workspace administrator for this domain, and I’ve confirmed in the Admin Console (Security > Access and data control > API controls > App access control) that all Google services, including “Cloud Platform,” are set to unrestricted for the organization. So this does not appear to be an org-level policy restriction.
  • My use case is a legitimate small, non-commercial personal project: a family-only educational chat app for my children (elementary school students) to ask study questions, gated behind Cloudflare Access so only my family can use it.

Could you please investigate why my account/project is being denied access, and restore access if this was applied in error? I’m happy to provide my project ID, API key ID (not the secret), or any other verification details needed.

Thank you for your help.

Hello @nakashige43,

Getting a 403 API error response and / or seeing “Unavailable” next to your project in AI audio indicates a flag has been placed on your account. To proceed:

  1. Check for banners / error callouts in the AI Studio Projects page & the Billing page.

  2. If the issue isn’t clear from the above, contact Cloud Billing Support.
