Site24x7 API Step Performance Report: how to get all steps execution time on a period?

Dear all,

Refereing to my screen shot for the colors.
Web site Site4x7 provides the Step Performance Report and give for Web monitoring the steps details (blue) for a period.
I need to automate this report on all web monitors (red) and all the steps I manage (green).
How to do this using the API if possible?

Kind regards,
Ronan
