I am using the Gemini API for post-payment, and I got the following error.

\*\*  
ClientError\*\*: 429 RESOURCE\_EXHAUSTED. {‘error’: {‘code’: 429, ‘message’: 'Your prepayment credits are depleted. Please go to AI Studio at [https://ai.studio/projects](https://ai.studio/projects) to manage your project and billing. Learn more at [https://ai.google.dev/gemini-api/docs/billing#prepay](https://ai.google.dev/gemini-api/docs/billing#prepay). ', ‘status’: ‘RESOURCE\_EXHAUSTED’}}

It seems now you have to be in Tier 3 to be able to change back to Postpay.
