The trust rankings are determined by millions of users in the active WOT community. The MyWot API provides access to the reputation rankings in four categories: trustworthiness, vendor reliability, privacy and child safety. In addition to the 0-100 reputation, MyWot provides a confidence score for how reliable the system believes the score to be.
