  In this work, we use angular diameter distances of 38 galaxy clusters with
joint X-ray/SZE observation to circumvent the circularity problem in the Amati
relation for Gamma-ray Bursts (GRBs). Assuming the validity of cosmic-distance
duality relation, we obtain the luminosity distance from the cluster angular
diameter distance and use that to calculate the isotropic equivalent energy of
two different GRB datasets, after restricting the GRB redshift range to
$z<0.9$. We then check the validity of the Amati relation for both these
datasets. The best-fit Amati relation parameters using galaxy cluster distances
as low-redshift anchors are consistent with a previous estimate for the same
dataset. The intrinsic scatter which we obtain for the two datasets is about
45% and 15%, and is comparable with that found by other distance anchors used
to vet the Amati relation.
