Show HN: I made a site that calculates the market price of items on ebay.

I 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!

I keep getting an error:

Application Error

Sorry! It should be ok now.

Now it's throwing a 500 error that says: "Sorry, we stuffed up. Please try again."

Can you dive more into the technical details of this, eg. are you using the ebay API or are you scraping the data?

[locksley → klous]

Yeah 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 → locksley]

And the scraper is using a "logged in" ebay account, correct? Because I believe to view completed listings you need to be logged in.

Perhaps implement a cache for the results? It already seems to be being hit quite hard!

This made me laugh aloud.

Sadly just reporting an error when I tried.
