Abstract
A facility for assessing availability of an item for purchase from a merchant using a model of the availability of the item is described. The facility receives asynchronous messages identifying changes in the merchant's inventory for the item that affects the availability of the item for purchase from the merchant. For each received asynchronous message, the facility updates the model to reflect the changes in the merchant's inventory identified in the message. The facility then evaluates the state of the model in order to assess availability of the item for purchase from the merchant.
