descriptionstringFixed string: "peaqOS machine"
didstringMachine DID derived from the machine wallet address (did:peaq:<wallet_address>)
activebooleanAlways true for registered machines
servicesarrayList of service endpoints. Contains one "web" entry if a data_api attribute is configured on the DID document; otherwise empty.
services[].namestring"web"
services[].endpointstringValue of the data_api DID attribute
data_visibilitystring"private", "onchain", or "public". Defaults to "private" if the DID document has no data_visibility attribute.
