Get the device search filter catalog
Return every criterion a device filter accepts — each with its key, valueType, allowed operations and live company values — plus the custom fields defined for devices. This is the vocabulary for getDevices: use a criterion’s key as the filter key and one of its values inside the clause ({"<key>":{"operationType":"INCLUDE","values":["<value>"]}}). Call this first whenever you are unsure a criterion exists — getDevices rejects an unknown key with 400. To build a device group target instead, use getDeviceGroupFiltersOptions: device groups accept a deliberately narrower set of criteria, because a group targeting a volatile criterion would change population daily.
