403 PERMISSION_DENIED — "Your project has been denied access" — Request for manual review

Gemini API
1

Hello Google Gemini API Team,

I am requesting a manual review of my Gemini API access.

My project is unable to use Gemini API content generation. Every generateContent request returns:

HTTP 403 PERMISSION_DENIED

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

Project name:
CODE 1440 Gemini

Project ID:
code-1440-gemini

I have performed direct REST API tests outside of my application.

Test 1 — List models:

GET https://generativelanguage.googleapis.com/v1beta/models

Result:
HTTP 200 OK
50 models returned
gemini-3.6-flash is present

Test 2 — Direct content generation:

POST https://generativelanguage.googleapis.com/v1beta/models/gemini-3.6-flash:generateContent

Result:
HTTP 403 PERMISSION_DENIED

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

I tested this directly from PowerShell using the API key, without using my Android application or Supabase backend.

I also tested both API keys associated with this project, and both receive the same 403 error when calling generateContent.

Google AI Studio chat itself works normally.

The Gemini API / Generative Language API is enabled for the project.

My intended use is personal development and testing for a productivity application called CODE 1440.

I would like to remain on the Free Tier and am NOT requesting a Paid Tier upgrade.

Could you please manually review the Gemini API access status of this project and determine why generateContent access is being denied?

I have not included any API keys or private credentials in this post.

Thank you.

Hello @Mr.Dev_1440 ,

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:

If you’re on the free tier with no billing attached, please try the below steps:

  1. Check Model Availability & Rate Limits:

    • Ensure that the model you are requesting is available on your current plan. For example, not all models are available on the free tier. You can verify model availability, quotas, and limits on the AI Studio Rate Limit dashboard.

  2. Ensure you have completed age verification by navigating to Google Account Age Verification and verifying date of birth in Google Account Personal Info.

  3. Complete Phone Verification and turn on 2-Step Verification (2SV) on the Google Account associated with your project.

  4. Once age, phone and 2sv are configured, retry your request or create a new API key in Google AI Studio.

  5. If completing these steps still does not restore access (or if using a model requiring a paid tier), you might want to consider adding prepayment credits directly in Google AI Studio and/ or attaching a Google Cloud Billing account in the Google Cloud Console. Please note this will mean you lose your free tier quota.

Hello Google Gemini API Team,

I am requesting a manual review of my Gemini API access.

My project PeryantoPC is currently unable to use Gemini API content generation. Every generateContent request returns:

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

I have confirmed that Gemini API (generativelanguage.googleapis.com) is enabled and that the request reaches Google successfully, but generateContent is rejected. Google AI Studio currently shows the project’s Billing Tier as Unavailable.

I would like to remain on the Free Tier and do not want to enable billing.

Project name: PeryantoPC
Project ID: peryantopc

Intended use: personal development and testing of an AI podcast/content automation project using the official Google Gemini API.

Could you please manually review the access restriction on this project/account and restore Gemini API access if it was applied in error?

Thank you.
