Prepay setup page is blank and Gemini API returns 429 for my project

Hello Google AI team,

I need help with a billing/prepayment issue on my Gemini API project.

Project name: Jo muflih
Project ID: jo-muflih

The project is linked to a Google Cloud Billing account.

In Google AI Studio, the project shows Paid Tier 1, but the Gemini API Billing page says that no prepayment method is set up.

When I click “Set up prepay” and then “Agree & continue”, the page becomes completely blank/white and I cannot complete the prepayment setup.

My API requests return this error:

429 RESOURCE_EXHAUSTED

“Your prepayment credits are depleted. Please go to AI Studio to manage your project and billing.”

I have already tried:

  • Refreshing the page
  • Using Chrome normally
  • Allowing third-party cookies
  • Using a different API key from the same project
  • Checking the Google Cloud Billing account
  • Reopening the AI Studio billing page

The problem still persists.

Could you please check whether the billing/prepayment status for project “jo-muflih” is synchronized correctly and help me enable the required prepayment setup?

Thank you.
