For convenience, we offer an API around the CT Logs: https://ctl.shodan.io/
It has an API endpoint that returns the subdomains for a domain based on the CT Logs. Ex: https://ctl.shodan.io/api/v1/domain/microsoft.com/hostnames

In 2016, somebody decided to write a worm that compromises Ubiquiti devices, change their hostnames to match how the system was compromised and close off the service. Years later the worm is still active with hundreds of compromised systems: https://trends.shodan.io/search?query=tag%3Acompromised+ubiquiti#overview
