Please help! Getting reports in certain circle using api



I need you help urgently. I want to use ushahidi public api to get incidents in certain circle in location. For example I want to get all incidents that in range of 500 meters from certain location.

How can i do that. In the documentation i found by location name and location id but nothing related about certain region according to longitude and lattitude.

I started a project and spent lots of time in It and this issue is just showstopper

Your Support is highly appreciated.

Thank you
