Work with SentryAPI

Hi everyone,
Me and my team are working on a project ,which requires getting data from Sentry API. I have seen documentation about Api(https://docs.sentry.io/api/) ,but haven’t seen anything about getting “organization saved searches” (https://blog.sentry.io/2016/01/19/introducing-saved-searches) from api. Our goal is to get “organization saved searches” and then retrieve issues by them. Is it possible? Maybe, Sentry has another type of filters, which you can save in Sentry and then retrieve issues by them?

Second question is about library,to work with Sentry api and getting data from it. Is It exits?Or we need to write our own library to goals from first question?

Thank you so much!
