Reading My Frequent Team Sites

Hi ,

I want to read the frequent team sites on SharePoint Online accessed by the logged in person and display the list on those SharePoint Online sites in another .NET application. Can you let me know 

- what is the API to read the SharePoint Online frequent team sites available for a person 
- is there a sample to help, which uses SharePoint Online Search REST API. 

Kindly help.

Thank you.
