  The high energy asymptotics of QCD correlation functions is often used as a
test for bottom-up holographic models. Since QCD is not strongly coupled in the
ultraviolet domain, such a test may look questionable. We propose that the sum
over resonance poles emerging in correlators of a bottom-up model should
reproduce the structure of a Veneziano like amplitude at zero momentum transfer
assuming equivalence of spin and radial states in the latter. This requires a
five-dimensional background that suppresses the ultraviolet part in the
effective action of a model. We give examples of emerging low-energy
holographic models.
