Issue in fetching OpenAI API usage, billing cost, and credit balance programmatically for backend monitoring

Hi everyone,

I’m trying to fetch OpenAI API usage, billing cost, and credit balance programmatically for backend monitoring.

I tried calling the below endpoints. GET /v1/usage GET /v1/dashboard/billing/usage GET /v1/dashboard/billing/credit_grants GET /v1/dashboard/billing/subscription

But did not get any response from these endpoints.
