CartrouteChangelog
API and product changes, newest first. Breaking API changes ship under a new dated API version; the current version is 2026-09-01.
Every condition, in stock only
Renewed, refurbished, open-box and used offers are now returned with a condition label, up to 10 offers per retailer per product. The best offer is always new when a new unit is in stock. Out-of-stock offers are no longer returned. New search filter: condition=any|new|used (replaces in_stock).
Live prices from Amazon, Best Buy and eBay
Searches now return live new-condition listings from Amazon, Best Buy and eBay, grouped by product with the retailer listing title on every offer. Responses state data_source: "live" and a live object with the fetch time. Price history is recorded daily from this date.
