A linear correlation between X-ray and optical CORCHETE_OPENOIIICORCHETE_CLOSE line luminosities in AGN is thought to manifest the ionization of low-density gas by the field of high- energy photons from the central black hole vicinity. It is often used to estimate the AGN ionizing flux from optical spectra. We identified 33 AGN powered by low-mass BHs openPar<6e5 MSunclosePar. They form a tight openParspread 0.23dexclosePar sub- linear openParL_OIIIvirgulL_Xelev0.48closePar relation that steepens and puffs up once more massive objects are included. We propose to observe a complete flux limited sample of 21 AGN with low-mass BHs openPar<1e6 MSunclosePar with available optical IFU spectroscopy. We will pin down the transition mass where the L_OIII-L_X slope changes and check whether it is connected to AGN-driven outflows comma internal structure comma dynamics comma and star formation
