Getting a 403 error saying Project has been denied access

Getting a 403 error on my Gemini API and it sayd Your project has been denied access. Please contact support.
Need help to get this rectified ASAP.

Hi @GTM_Contrails ,

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.
