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!
