The superconductors with the Ginzburg-Landau (G-L) parameter ($\kappa$) $\sim1/\sqrt{2}$ exist near a critical Bogolomonyi (B) point where they show inter-type domains between type-I and type-II superconductivity. While such physics is well understood for isotropic superconductors, experimental investigation of anisotropic B-point remains an unattained goal mainly due to unavailability model material systems. Theoretically, are expected or behaviour definite directions applied magnetic field. Here, from directional point-contact Andreev reflection spectroscopy field-angle dependent ac susceptibility measurements, we that ZrB$_{12}$ superconductor, it exhibits field-direction behaviour. These observations match remarkably theoretical expectations superconductor B-point. Therefore, our results project as system superconductivity can be explored experimentally.
