Yard Puller

Used auto parts, valued before you pull them. A tool for the people who recover parts from self-service salvage yards and sell them on eBay. Calgary, Alberta.

What it does

Pulling a part costs time whether or not it is worth anything, so the question that matters is which parts are worth recovering before driving to a yard. Yard Puller holds a catalogue of part numbers, values each one against what the same part is currently listed for and has recently sold for on eBay, and ranks what is standing in the yards by what a visit is actually worth.

How it uses the eBay API

eBay Browse API
One search per part number, returning that part's live competing listings. Results are cached and re-measured on a graded schedule โ€” high-value numbers daily, dormant numbers monthly.
Seller connection (planned)
The next version lets an operator connect their own eBay seller account, through eBay's own sign-in, so that a part they have pulled can be listed from the tool. Until that version is live the application holds no user tokens and no user account data.

Data handling

Today the application authenticates with client credentials only. It has no user login and does not access, collect or store any eBay user account data; what it retains is aggregate and non-personal โ€” part numbers, listing counts, price statistics. When seller connection ships, each operator's account data will be kept separately, used only to serve that operator, and deleted on their request or on notice from eBay. The full privacy policy says exactly what is kept and for how long.

Status

In daily production use by the business it was built for. Not yet open for public sign-up.
