Thought process Thought process Titel: Request for manual review — 403 PERMISSION_DENIED: "Your project has been denied access"

Gemini API
1

Hello,

API access to the Gemini API is denied for every project under my account. AI Studio in the browser works normally, which points to an incorrect block on API access rather than a policy problem.

Account

  • Google Workspace account, region Netherlands

Affected projects

  • gen-lang-client-05126077.. — Default Gemini Project, created 8 July 2026
  • gen-lang-client-07243952.. — Verver-com, project number 5933298255.., created 17 July 2026

Request and response

POST https://generativelanguage.googleapis.com/v1beta/models/gemini-2.5-flash:generateContent

json

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

Billing

  • Linked and active, Tier 1 Prepay, balance topped up today. The error is identical on the paid tier.

Usage

  • None. Monthly spend shows €0.00. The projects have never processed a successful request.

What I have already tried

  • A brand-new project (Verver-com) with a newly created API key, linked to the same billing account. Identical error.
  • A second Google Workspace account under a different domain. Identical error.
  • The API key is restricted to the Generative Language API and bound to a service account, in line with the June 19, 2026 policy on unrestricted keys. The 403 occurs regardless.
  • The call is a single-image generateContent request from a server-side function, well within rate limits.

There is no known policy violation and no usage history on either project. Could you review the account and restore API access for these projects?

Kind regards,
Mark Verver
