Sold prices from more than one source, with automatic failover

Your number never rests on one feed. For US and UK scans a specialist eBay sold-price API goes first and asks again with broader words when an item is described too specifically, and an independent backup service steps in if that call fails (in Canada, Australia and the larger EU markets that service goes first), and our own archive of over a million sales covers the rest. Some categories add a specialist source, such as Discogs for records or Poshmark for fashion.
