Accessing OpenAI billing metrics via API

[chicken_nuggets]

Hello,

I want to view real-time billing metrics all in one place on my website, so it would be very helpful if I could access my OpenAI billing through an API.

Thanks

“Billing metrics” is a rather ambiguous desire, but you can use the “costs” endpoint with an admin API key, that an owner can create in the platform site.

Here’s a quick Python script using that key set as environment variable to print a daily report by model (and yes, the API is currently working today):

Prepaid $10 for gpt-image-1, generated lots of images via API, but usage + costs still show $0

You will first want to go into the usage page: https://platform.openai.com/settings/organization/usage Then near top, select “Group by” → “Line Item”. That should show a bar graph display for the date range with the billed parts by model usage when you hover over a bar, and a legend at the bottom with the total for the period selected. For your API call, maybe it is the “costs” endpoint not behaving like you expect. It is limited to 7 days by default, requiring pagination, not obeying a range…

It will give costs similar to the main page of “usage”, collected daily buckets that can lag behind a bit, but shows you dollar figures.
