I need an application that can retrieve item prices from Half.com.? I believe this can be done using Ebay Web Services.? Since I'm not that familar with Ebay Web Services and what is possible, ? I am going? provide 2 possible ways to accomplish what I? need.
1)? ? This application will run in the background and alert me (popup notice) whenever a particular price has been reached for a particular item.? I will need to be able to populate an input file with a large number of product IDs and a corresponding price for the alert for the application to use.
If it is not possible to do this, then I would like the application to use the following method:
2)? ? The application will accept an input file that? I will need to be able to populate with a large number of product IDs.? The application? will then? retrieve the lowest 2 prices associated with each item and present all of the products and prices in a table.? This table needs to be sortable by price.
Finally, it looks like there are some limitations to the number of API calls allowable? per day.? I need to be able to run this program multiple times a day and it will involve hundreds of products, I would like to avoid exceeding the API call limit if at all possible.
