Count data from other websites

Hey,
I want to count data or however it is called from other websites on my wordpress blog, for example: I want to count how many some specific items are here https://backpack.tf/profiles/76561198128826431 or from here https://steamcommunity.com/id/masinac_3d/inventory (There are same items) . Is there any way to do so ? I’m new to wordpress so I might not understand everything. Thanks !
