How to check LB's total number of origins?

Developers API
1

Hello.

I’m using CloudFare’s Load Balancer.
I understand that there is a limit to the resources available.
So, I want to check total number of LBs and origins using CloudFlare API.
The number of LBs is likely to be possible, but the number of origins currently generated seems to be difficult to inquire through APIs.
Am I wrong? Please let me know that there is a possible way.

Thanks.
