Are credit grants just a scam?

There might be some confusion here.

“Credit Grants” in billing shows anytime a balance is loaded to an API organization. That can be your payments.

It is made worse because OpenAI is not showing the real purchase date or date they were added. The “Received” is false, back-dated to the start of the month for their own obfuscation and confusion-providing.

The balance $0.00/X.XX means you have exhausted the particular balance of the line item.

API Data sharing, free tokens per day on certain models when enrolled, is simply never billed.
