There are some API:
1. Query commodity price of a given image. 
2. Recognize a specified object/commodity in a given image.
3. Query weather information.
4. Query agenda.
5. Query to-do list.
I will give you a task request. It is your job to find out a possible combination of some of the APIs I describe above to handle the task. Reply with the API names in an order that the task can be divided and conquered by using these APIs , no other words . My first request is: "how much does the bag in the video cost?" The word "reply" should not appear in your response.
