  Quantum resources are fundamental for the development of quantum technology.
Thus, verifying their presence is crucial for studying their role in various
information-processing tasks. Here, we enquire whether can one detect the
presence of a quantum resource in some operational task or equivalently does
every quantum resource provides an advantage over its free counterpart in some
black box scenario where one does not have much information about the devices.
We introduce the framework for detecting quantum resources semi-device
independently by considering the prepare-and-operation scenario with the
restriction on the dimension of the quantum channel connecting the preparation
box with the operation box. For any dimension $d$, we show that for any
resource theory with less than $d^2$ number of linearly independent free states
or free operations, there exist correlations that can detect the presence of a
quantum resource. For the particular case when the quantum channel is
constrained to transmit only qubits, we explicitly construct witnesses to
observe the presence of various quantum resources.
