Gemini Vision 403 PERMISSION_DENIED — Project gen-lang-client-064372505.. — Manual Access Review

Hello Gemini API Team, I am requesting a manual review of Gemini API access for my project. Project name: Default Gemini Project Project ID: gen-lang-client-06437250.. Billing tier: Free tier Model: gemini-3.6-flash The Gemini API is enabled and the API key is active and restricted to the Gemini API. I have completed the recommended account verification steps: - Age / date-of-birth information verified - Phone / recovery information completed - 2-Step Verification enabled - Gemini API enabled in Google Cloud - API quotas are available - API key is active - DNS/TCP/TLS connectivity is working A minimal text Gemini request succeeds. However, a direct Vision request using a completely synthetic, non-private PNG consistently returns: HTTP 403 PERMISSION_DENIED “Your project has been denied access. Please contact support.” The same result occurs after completing the account verification/security steps. This was reproduced outside of my main curriculum processing workflow, so it is not caused by PDF processing, application persistence, or a private document. Could you please manually review the Gemini API access state for this project and check whether there is a project/account access flag or restriction affecting multimodal/generateContent requests? I have intentionally not included any API key or private credentials. Thank you.

Hello @ahmed9 ,

It seems like your projects are flagged by automated account security checks. To unblock this error, you should consider upgrading to a paid plan. You could add prepayment credits directly in Google AI Studio and/ or by attaching an active billing account in the Google Cloud Console.
