How to get a list of changes for all project teams in the last hour via REST API?

[evgeniy]

I need to find out which users have been removed/detached from all projects in the last hour via REST API. 

Going through all projects and checking the relevance of the current command does not suit me, since this action heavily loads the system. I need to do this with the minimum count of requests to JIRA

Hello @evgeniy  Welcome :) 
did you try using the Jira Audit Logs API 
GET /rest/api/3/auditing/record 

https://developer.atlassian.com/cloud/jira/platform/rest/v3/api-group-audit-records/#api-rest-api-3-auditing-record-get

or as a Admin you can check the Audit log and try to export the related need to an excel.
