Error code: 429 while having sufficient balance

I have been using API for the past few months , everything works. All of sudden , it started reporting errors: -
Error code: 429 - {‘error’: {‘message’: ‘You exceeded your current quota, please check your plan and billing details. For more information on this error, read the docs:’, ‘type’: ‘insufficient_quota’, ‘param’: None, ‘code’: ‘insufficient_quota’}}
Actually, for the last month, I haven’t used any of my quota yet as I focus on building UI and deployment, so that this doesn’t looks like a exceeding quota issue or rate limit issue.

I have been trying very hard and couldn’t figure it out while I am sitting $200 quota without using a cent .


It’s resolved. For Now: on the billing page, we need to either add credit balance or enable auto recharge.
