A domain reputation checking tool that determines if a domain is present in the Alexa or Cisco top one million domain lists. The tool provides both a user interface and API for programmatic access, making it suitable for integration into security workflows and automated systems. Installation is available through pip package manager or by cloning the repository directly. The application includes functionality to check if domain lists have been updated on the current day and compares etags to ensure data freshness. When querying a domain, the tool searches through the top one million domain lists to determine if the specified domain appears in these reputation databases. This capability is useful for threat analysis, domain reputation assessment, and identifying potentially malicious or suspicious domains that fall outside of commonly visited websites.
