Is there a self hosted Postman API?

Is there a way to have a self hosted postman api?

I really like, but it would be awesome if I could have a self hosted one for our cicd and monitoring pipeline.

As an ops engineer I want to enable devs to upload their postman scripts they use for monitoring and alerting.

My idea was to use something like prometheus blackbox exporter to query the postman api to get the health of our kube env and services.

I was thinking of writing something similar to the API using Newman if nothing like this exists.
