With access to over 5 billion indexed subdomains sourced from Certificate Transparency, passive DNS, and X.509 data, sub.md provides a robust solution for researchers seeking efficient data extraction without the hassle of active scanning or SDK dependencies. 

The API facilitates simple and seamless integration using just one curl call, delivering plain-text output that is easy to read and utilize.

Sub.md's pricing structures cater to various needs, including a free tier for casual users and multiple subscription options for professional researchers, complete with higher query limits and dedicated support. An upcoming dashboard will further enhance functionalities by monitoring attack surfaces continuously and tracking changes across large portfolios. This tool is designed for operational efficiency and ease of use in the cybersecurity landscape.
