Gemini API 403 PERMISSION_DENIED: Project denied access

Hello,

I’m requesting a review of Gemini API access for my project.

My application successfully reaches the Gemini streaming endpoint, but Google returns the following response:

{

“error”: {

“code”: 403,

“message”: “Your project has been denied access. Please contact support.”,

“status”: “PERMISSION_DENIED”

}

}

Project ID: [YOUR PROJECT ID]

Account type: Google Workspace account

Region: United States

Application: AquaHunter Intel AI Companion

SDK: Vercel AI SDK with @ai-sdk/google

Requested model: gemini-3.6-flash

I have verified that:

- The API key is loaded by the server.

- The request reaches the Gemini streamGenerateContent endpoint.

- The same request consistently returns HTTP 403.

- The error is marked as non-retryable.

- The application does not expose the API key to the browser.

- The project is being used for a legitimate AI companion development prototype.

- No bulk automation, scraping, or intentional policy-violating activity is involved.

Could you please confirm whether the project, account, or Workspace domain has been restricted and review it for reinstatement?

I can provide the project number and sanitized request details privately if required. I will not post the API key publicly.

Thank you.
