Instagram: Our service has two ways of posting: SMMplanner API and Instagram API. SMMplanner API is our extended API. Posts are published through an emulated Android device, which means Instagram sees them as sent from a regular mobile device and they get the same reach as if you published them from your smartphone. Instagram API is a limited API made by Instagram. Posting is realized by Instagram itself, thus not reducing your reach either.Detailed API comparison table
VK, Facebook, OK, Twitter, Telegram, Viber: We work with these networks through their official APIs, meaning each network gives us their documented API with posting privileges. Therefore they have no reason to reduce the posts' reach, since we bring traffic to their network.
