We present a new X-Ray Accretion Disk-wind Emulator (\textsc{xrade}) based onthe 2.5D Monte Carlo radiative transfer code which provides aphysically-motivated, self-consistent treatment of both absorption and emissionfrom a disk-wind by computing the local ionization state and velocity fieldwithin the flow. \textsc{xrade} is then implemented through a process thatcombines X-ray tracing with supervised machine learning. We develop a novelemulation method consisting in training, validating, and testing the simulateddisk-wind spectra into a purposely built artificial neural network. The trainedemulator can generate a single synthetic spectrum for a particular parameterset in a fraction of a second, in contrast to the few hours required by astandard Monte Carlo radiative transfer pipeline. The emulator does not sufferfrom interpolation issues with multi-dimensional spaces that are typicallyfaced by traditional X-ray fitting packages such as \textsc{xspec}.\textsc{xrade} will be suitable to a wide number of sources across theblack-hole mass, ionizing luminosity, and accretion rate scales. As an example,we demonstrate the applicability of \textsc{xrade} to the physicalinterpretation of the X-ray spectra of the bright quasar PDS 456, which hoststhe best-established accretion-disk wind observed to date. We anticipate thatour emulation method will be an indispensable tool for the development ofhigh-resolution theoretical models, with the necessary flexibility to beoptimized for the next generation micro-calorimeters on board future missions,like \textit{XRISM/resolve} and \textit{Athena/X-IFU}. This tool can also beimplemented across a wide variety of X-ray spectral models and beyond.
