Show HN: I made a site that calculates the market price of items on ebay.
- locksley 14y agoI made this in rails over a couple of weekends after learning how to code late last year. The inspiration came from wanting to buy an iPhone 5 from ebay but not knowing what a fair price should be. After a writing a script to calculate this for myself, I thought it could be useful for others too and abstracted it into its current incarnation. Any feedback would be fantastic, especially on UX!
- Pezmc 14y agoPerhaps implement a cache for the results? It already seems to be being hit quite hard!
- byoung2 14y agoI keep getting an error: Application Error An error occurred in the application and your page could not be served. Please try again in a few moments. If you are the application owner, check your logs for details.

- locksley 14y agoSorry! It should be ok now.
- pavel_lishin 14y agoNow it's throwing a 500 error that says: "Sorry, we stuffed up. Please try again." http://i.imgur.com/zhNDB.png http://i.imgur.com/zhNDB.png
- bdfh42 14y agoSadly just reporting an error when I tried.
- klous 14y agoCan you dive more into the technical details of this, eg. are you using the ebay API or are you scraping the data?
- locksley 14y agoYeah sure, it's a scraper. The histogram is then built out of the 200 results retrieved from 'completed listings', minus the ones that weren't sold. The X/Y scatter plot is built from the 200 upcoming results, intended as a way to find good bargains after you know the median/mean price.
- klous 14y agoAnd the scraper is using a "logged in" ebay account, correct? Because I believe to view completed listings you need to be logged in.
