Discover SSH Host Key

Specific question: is it possible to schedule a discovery for SSH Host Key in the web GUI or is it possible to create a script using API to do the discovery of the SSH Host Key of all linux assets?

just the same as selecting a single linux server and running Discover SSH Host Key from the menu but in this way i can do it only for one server linux at time but we need to execute this command for all the linux server automatically for example every day...
