Why do bot detection tools examine browser API inconsistencies?

Browser API inconsistencies can reveal automated browsers that patch or hide their true environment. BotRefund uses a native patching check to spot these mismatches, comparing what a real browser shows versus what an automated one reveals. Because many legitimate situations can cause similar anomalies, BotRefund treats this as one of many signals, not a decisive proof. The final prediction is made by an AI model that weighs all evidence together.
