The transcribed information includes attribute information indicating an attribute of electric power related to power trading.

Abstract: An agent is an information processing apparatus that puts in a bid to allow a vehicle to conduct transaction of power reception/provision through a transaction market server. In the event of nonfulfillment of transaction which means that the vehicle does not conduct transaction of power reception/provision, the transaction market server performs penalty processing for imposing a penalty on a user of the vehicle. The agent includes a bid processing unit and an indicator value calculator. The bid processing unit is configured to put in a bid to the transaction market server. The indicator value calculator calculates an indicator value that represents an extent of the penalty imposed on the user in the penalty processing. When the indicator value reaches a threshold value, the bid processing unit suspends a bid.
