Hello!
I worked on a small PHP API client wrapper around the Fly machines API. I hope you find it useful. A quick note, I did not test if every implemented function is working properly since I only use a small part of the package and wrote the package by looking at the flyctl golang code.
This is my first Laravel package, so please be kind 
.
https://github.com/SecurityDiscovery/laravel-fly-machines
A simple example:
use SecurityDiscovery\LaravelFlyMachines\Facades\LaravelFlyMachines as FlyMachines;
// List machines of an app.
$machines = FlyMachines::machines('my-fly-app')->list();
Of course, there is plenty of room left for improvement. For instance, someone could try to map the response to an object (type-hinting, etc) or implement tests .
Feel free to check it out. The README also contains more examples!
