    • itemType integer Required

      Must be 2

      Value is 2.

    • token string Required

      The item's token contract (with the null address used for native tokens) Token address

    • identifierOrCriteria integer Required

      The ERC721 or ERC1155 token identifier or, in the case of a criteria-based item type, a merkle root composed of the valid set of token identifiers for the item. This value will be ignored for Ether and ERC20 item types, and can optionally be zero for criteria-based item types to allow for any identifier.

    • startAmount integer Required

      The amount of the token in question that will be required should the order be fulfilled.

      When endAmount differs from startAmount, the realized amount is calculated linearly based on the time elapsed since the order became active.

  • startTime integer Required

    The block timestamp at which the order becomes active.

  • zoneHash string Required

    A value that will be supplied to the zone when fulfilling restricted orders that the zone can utilize when making a determination on whether to authorize the order. Most often this value will be the zero hash 0x0000000000000000000000000000000000000000000000000000000000000000.
