Tracking Usage Separately for Shared GPT-4 API Keys - Seeking Suggestions

I just gained access to the GPT-4 API and managed to create multiple API keys. I made a new one for my brother, who’s still on the waiting list, and shared it with him. I’d like to track usage for each key so he can pay me back for his usage. However, I’m having trouble finding a way to filter out usage based on API keys. Does anyone know if there’s a method to track this separately? Any suggestions would be appreciated

I want to know it too, maybe the team can help solve the usecase.

Hi @amazingpaddy

Welcome to the community.

That functionality isn’t doesn’t exist.

Also, sharing the API keys is prohibited by the OpenAI ToS.
