  We evaluate closed string disk amplitudes in the pure spinor formalism. We
focus on low point functions (two- and one-point functions) but our analysis is
also relevant for higher n-point functions. Amongst others we discuss issues
arising due to the gauge fixing of the conformal Killing group of the disk and
due to the zero mode prescription in the pure spinor formalism. As expected, in
the end we find agreement with the known results from the RNS formalism.
