API error: Error code: 429 but no API usage in settings

I am getting below error for API call:

OpenAI API error: 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: https://platform.openai.com/docs/guides/error-codes/api-errors.’, ‘type’: ‘insufficient_quota’, ‘param’: None, ‘code’: ‘insufficient_quota’}}
Could not get an answer from GPT.

But, I see I didnt spend anything. Attached is my usage and billing.
Can anyone explain how do i use free tier?

The image shows you were given free api credits in 2022. Which expired in 2023. No matter. If this is your first time discovering the API and creating a new account, you would find that the free trial credit program has been discontinued anyway.

Your next destination is to click on “billing”. It will say you have a balance of $0.00 to pay for API services. You need to prepay, purchasing credits. Throw in $5, wait a bit, and thus, after you checked your plan and billing, you will see the message about checking your plan and billing has gone away.
