Connections that you make to OpenAI, using your API keys, should be coming from datacenter locations known by you. There should be no reason why you do not know how and where your API keys are being employed, such as client applications that connect directly to OpenAI and not through you.
OpenAI does not provide you a detailed log of what you are doing, neither with accounting of individual API calls and how they are costing you, nor showing the IP addresses employed.
