The Accuracy score on eBay sold listings APIs

This score out of 100 shows how complete a provider's answer is on each search.

  • We send each call the words of a search, as a buyer types them on ebay.com.
  • We have no copy of eBay's sold listings to check an answer against.
  • We compare the answers of four calls instead: two from CompsAPI, one from Trawl and one from CompSniper.
  • For each search, we count the parts in the answer, such as the sold listings and each listing's price.
  • We count a part on a search if any call's answer had that part.
  • On each search, we divide the parts a call gave by the parts in all four answers together.
  • For the sold listings part, we count the listings in the answer.
  • We divide the call's listing count by the largest listing count of the four answers on that search.
  • We count no more than 240 listings, the most one call of CompsAPI returns.
  • A sold listing also has parts, such as the price.
  • For each part, we count the share of a call's listings that have the part.
  • The two calls of CompsAPI may send stored answers up to 15 minutes old.
  • Trawl also sends stored answers.
  • CompSniper is the live call: CompSniper reads eBay's sold history at the time of the call.
  • We score a stored answer the same way as a fresh answer.
  • We average the results over all searches.
  • Every search counts the same.
  • A call scores 0 on a search when the call found no sold listing.
