Run curl command to run a playbook in semaphore against a specified host without using inventory?

[jengstrom440]

I would like to run a curl command to semaphore API to tell it to use the hostname of the system it is calling it as the inventory to run against instead of specifying it in an inventory or using a survey. I want it to pick up the hostname system variable to run against, not an ansible variable. How would one go about doing that? My only workaround so far is SSH to the ansible server, and run ansible-playbook and bypass semaphore completely, which defeats the point of having semaphore. Any ideas? I have spent a considerable amount of time attempting to get this to work and have gotten close, but not quite there. Thanks in advance.
