eBay Price Research Help

This page describes how to use the eBay Price Research Utility. This utility provides an interface to the free Advanced GetPriceResearch call. This call allows some basic research on current prices for items on eBay.

This interface is a shared resource with only 1000 searches per month. Search counts are limited so please do not overuse the script. There is support to limit the number of searches and you may sometimes encounter an error message. In that case, simply search again tomorrow.

Current Input Includes:

• Query: A set of search keywords. The interface does not accept advanced eBay syntax (such as, -foo to exclude any listings with foo in the title).
• Min Price, Max Price: Price range specification. This is useful for limiting search to specific items. For instance, if you are looking for used Canon 5D prices (which usually runs around $1100), limit the price range to $500 to $1500 to exclude the 5D Mark II.
• Category: A few camera specific categories are provided. Only child categories are supported by the call, meaning it is impossible to only search Camera & Photo or Film Cameras categories. Currently having trouble with this feature -- please set it to All Categories

Current Output Includes:

• Total Items: The total number of items sold in the past 30 days is listed first.
• Pseudo-Histogram: A histogram of recent prices is simulated based on the day by day min/max/average price information returned from the call. This histogram is most accurate when at most three listings are returned per day, typically for less than 100 items.
• Median, Average, Range, Quartiles: Basic statistics of the prices over that time period are returned. The average and range are accurate, the median and 25th/75th quartiles are simulated (most accurate for < 100 items). The median, in particular, gives a good estimate of the going rate for an item.
• Daily Sales Statistics: A table showing total items, average price, minimum price, and maximum price for each day returned by the search.

Have fun with it! Feel free to experiment!

Next feature planned: Live eBay auction listings for the research query. Find the going rate then find an auction you can bid on!
