I am working as a Problem Curator in Hackerearth. As Hackerearth conducts challenges in different domains , due to which it creates a long list of challenges in clist. Due to the same reason, when people decide the date and time of the challenges on their website, specially (competitive) by reffering clist.by, they miss out our important competitive challenges, which leads to clash in time and date. So we have created different api, through which you can only show competitive challenges on clist. It will resolve the mentioned issue. Please find the required end point here .
