The NFTs Pricing Details endpoint has been enhanced to incorporate the NFTTransferBlockchainEvent structure, which offers details about the chain position for the latest sale event. In order to accomplish this, a new field called last_sale has been introduced, encompassing the blockchain_event and recipient_paid data to represent the chain position and pricing details respectively. Meanwhile, the last_sale_price field has been deprecated and is scheduled for removal on September 1st, 2023.
