The rate limit of each secret keys

Hello developers,

I have a question about the rate limitation of account. A personal account maximum could create 5 secret keys and use the account credits together. So how’s the way to measure the rate limitation? count the API request separately by each key? or sum the requests of each key per minute together?

It is on Organization level, not on key, nor on user level.

We enforce rate limits at the [organization level] not user level, based on the specific endpoint used as well as the type of account you have.
