Request for Manual Review – Gemini API 403 “Your project has been denied access”

Gemini API
1

Hello Google Gemini API Team,

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

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

HTTP 403 PERMISSION_DENIED

"Your project has been denied access. Please contact support."

I have already completed the relevant account verification steps:

  • Age verification completed

  • Phone number verification completed

  • 2-Step Verification enabled

  • I am using a personal Google account

  • I am located in Taiwan, which is listed as a supported region

I also performed direct REST API tests outside of any third-party application.

The results are:

GET /v1beta/models
→ HTTP 200
→ Model list is returned successfully

POST /v1beta/models/[model]:generateContent
→ HTTP 403
→ "Your project has been denied access. Please contact support."

I also tested the API through a different supported-region network exit. The model-list request continued to work, but generateContent still returned the same project-access error.

This appears to indicate that the project can authenticate successfully and access the model-list endpoint, but content-generation access is being denied at the project level.

My intended use is personal development and creative-writing experimentation. I would like to remain on the Free Tier and am not requesting any paid-tier upgrade.

Could you please review the access status of my Gemini API project and restore access if this restriction is a false positive?

For privacy reasons, I have omitted my email address, Project ID, Project Number, IP address, and API key from this public post. I can provide the project details privately if they are required for investigation.

Thank you for your help.

Hi @Bob8,
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. Verify your Google Account:

  3. Upgrade to a Paid Tier:

    • If verifying your account does not restore access (or if using a model requiring a paid tier), you can unlock access by adding prepayment credits directly in Google AI Studio or attaching a Google Cloud Billing account in the Google Cloud Console.

Hi Payal,

Thank you for your reply.

I have already completed the steps you mentioned:

  • My phone number is verified.

  • 2-Step Verification is enabled.

  • Age verification is completed.

  • I am using a personal Google account.

  • I am in Taiwan, which is a supported region.

  • I also created and tested a new API key.

The issue is not with the API key or model availability. I tested the Gemini API directly through REST:

GET /v1beta/models → HTTP 200, and the model list is returned successfully.

However:

POST /v1beta/models/[model]:generateContent → HTTP 403

with the exact error:

Your project has been denied access. Please contact support.

I also tested from a different supported-region network exit, and the result was the same.

Because the model-list endpoint works while generateContent is specifically denied, it seems that the restriction is applied to the project itself rather than being a normal account verification or API key issue.

Could you please let me know whether this type of project-level restriction can be manually reviewed by the Gemini API team? I am specifically requesting a review of the access restriction, rather than a paid-tier upgrade.

I would be happy to provide my Project ID or other project details privately if they are needed for investigation.

Thank you.
