Request for manual review — 403 PERMISSION_DENIED and all projects show Unavailable

Gemini API

Hello Google Gemini API Team,

My Gemini API projects previously worked normally on the Free Tier without a billing account.

On July 10, 2026, all existing projects suddenly became unavailable, and all Gemini API requests started returning:

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

Affected projects:

  1. Project name: AI-CHAT
    Project ID: gen-lang-client-08486882..
    Project number: 3966370459..

  2. Project name: Astrbot Gemini
    Project ID: astrbot-gemini-5020..

A newly created project also immediately showed Billing Tier “Unavailable”, so this appears to be an account-level restriction or provisioning issue rather than a single API key problem.

I have confirmed that:

  • I am the Owner of the affected project.
  • The Gemini API is enabled.
  • No warning, suspension, or appeal banner is visible in Google Cloud Console.
  • The Gemini API monitoring page shows a 100% error rate.
  • I have stopped all automated Gemini API requests.
  • I have corrected the deployment and network configuration.

No suspension or policy-warning email was received.

I have already submitted a report through the Google AI Studio “Send feedback” function.

Please manually review whether my account or projects were incorrectly flagged, and advise how I can restore Gemini API Free Tier access.

Hello @JaydenYale ,

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.

Hello, thank you for your response.

I checked both the Google AI Studio Projects page and Billing page, but there is no warning banner, error callout, appeal button, or explanation.

I also checked Google Cloud Console:

  • I am the Owner of the affected project.
  • The Gemini API is enabled.
  • No suspension or appeal banner is shown.
  • The API monitoring page shows a 100% error rate.

I previously used only the Gemini API Free Tier and do not have a Cloud Billing account. When I try to contact Cloud Billing Support, the assistant says that I am not an administrator of any billing account, so I cannot reach a support agent.

Could you please advise on an alternative appeal channel, or escalate this account flag for manual review?

Thank you.
