  We investigate a cosmological scenario by finding solutions using first-order
formalism in the Horndeski gravity that constrains the superpotential and
implies that no free choice of scalar potential is allowed. Despite this we
show that a de Sitter phase at late-time cosmology can be realized, where the
dark energy sector can be identified. The scalar field equation of state tends
to the cosmological scenario at present time and allows us to conclude that it
can simulate the dark energy in the Horndeski gravity.
