# Castle ## **What is Castle?** Castle is an anti-bot service designed to prevent automated attacks such as account takeovers, fake account creation, and policy-violating behaviors. It monitors browser characteristics, user behavior, and request patterns to detect malicious activity. ## x-castle-request-token When interacting with Castle-protected endpoints, you must include a valid `x-castle-request-token`. This token is generated using various browser-specific factors, including the `__cuid` cookie and other session details. Our API generates this token, making it easy to integrate with Castle-protected websites. An example website using it is [DailyPay](http://dailypay.com). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
