Do you pay 1 Energy to put Hall of Legends' ability on the chain?

When I use Hall of Legends to ready my legend, do I have to pay 1 Energy when placing that effect on the chain? If I am playing Rek'Sai, can I put Hall of Legends on the chain first, then use Rek'Sai's legend ability, and decide later whether to pay to ready the legend?
