Error HTTP 403 in API calls

Google AI Studio
1

Hi Google AI Community Team,
on May, 22th I created on Google AI Studio https://aistudio.google.com/ three projects with three API Keys and I used Gemma 4 26B or Gemma 4 31B models through API calls until today; now, with cURL (for example: https://generativelanguage.googleapis.com/v1beta/models/gemini-flash-latest:generateContent ) I always obtain error:
{
“error”: {
“code”: 403,
“message”: “Your project has been denied access. Please contact support.”,
“status”: “PERMISSION_DENIED”
}
}

If can be useful, for example one project has number: 836329140066.

What is the cause of this error?
How can I solve?

Thanks.

Alessandro

Hi Google AI Community Team,

I rewrite because the problem still persists and I am blocked.

I add an information: now on the page https://aistudio.google.com/rate-limit?timeRange=last-28-days appears a snackbar message:

Livello di quota del progetto non disponibile. Contatta l’amministratore del progetto per ricevere assistenza.

I have just compiled the form Report unexpected 403's in Gemini API but I got no reply.

Can you help me to solve the problem?

Thanks.

Hello @GEdAI-UniGe ,

This is very likely caused by an issue which is currently only visible in Google Cloud console. We’re working to move visibility of this into AI Studio. To resolve this:

  • Open the Cloud console & select your project
  • You should see a banner which explains the issue / may allow you to appeal

Hi @Mahesh_Sutar ,

in Google AI Studio https://aistudio.google.com/usage?timeRange=last-28-days I see that the motivation is:

Livello di quota del progetto non disponibile. Contatta l’amministratore del progetto per ricevere assistenza.

but I am on the free plan, so why I no longer have quota tu use the API with free plan?

Can you help me to solve the problem?

Thanks.

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.
