I see AWS Lists down available devices on this portal http://awsdevicefarm.info/ There is devices.js file that loads in this page that is essentiallly a json string containing details of devices.
I want to know is there a API call by which I can find list of all available devices in AWS Device farm. I am not able to locate that API.
You're looking for the list-devices API which will return a list of device type available in the public offering. However, it's not possible to list specific device instances if you're looking for a device with a specific UDID value.
