SoldStack
soldstack.fly.dev
SoldStack is a cloud-based API (software as a service) for developers who build tools for online resellers. Customers pay a monthly subscription ($9, $29 or $79) for a set number of lookups. Each lookup returns recent sold prices for an item from public resale marketplace listings, along with statistics like the median price, how quickly items sold, and estimated seller payout after fees. The service is fully automated and delivered online; there are no physical goods.
Sold prices from resale marketplaces in one API call: only the sales that match your item, the median, how fast it sold, what the seller kept after fees, and whether it's worth buying.
