AutoTrader.com Data Parser & API

AutoTrader.com is Cox Automotive’s flagship US car-shopping portal — around 26-28M unique visitors per month across millions of listings — and Carapis extracts its full listing data, including spec, price, dealer details and history-report links, through one REST API. Because Cox serves Kelley Blue Book (KBB) listings off the Autotrader inventory feed, AutoTrader.com and KBB are effectively one inventory backend — and Carapis delivers it without you building or maintaining an Akamai-protected scraper.

What is AutoTrader.com?

AutoTrader.com is a leading US car-shopping marketplace owned by Cox Automotive. It aggregates dealer inventory plus private-seller listings with full specifications, pricing, photos and vehicle-history links, and reports roughly 26-28M unique visitors per month (Cox, Dec 2025). As part of Cox Automotive, its inventory feed also powers KBB.com’s listings — so it sits at the center of a very large share of US dealer data.

Market Position

AutoTrader.com is one of the top US car-shopping portals with ~26-28M unique visitors per month (Cox, Dec 2025), alongside CarGurus and Cars.com. Its owner, Cox Automotive, also controls Kelley Blue Book (KBB.com) and the Manheim wholesale auction network — and KBB listings are served off the same Autotrader inventory feed. That consolidation means one parsing strategy across the Cox cluster (AutoTrader.com + KBB) unlocks a large, overlapping share of US dealer inventory, with Manheim adding the wholesale side.

Data Fields Available

Carapis extracts a complete structured record from each AutoTrader.com listing:

• Vehicle identity — make, model, trim, model year, VIN
• Condition — mileage and listing condition
• Pricing — listed price and price positioning
• Specification — factory options and trim packages
• Listing context — dealer name / location / ratings, private-seller info, photo gallery
• History — links to CARFAX / AutoCheck vehicle-history reports

Because the same feed backs KBB, AutoTrader.com is the most efficient single entry point into Cox-served US dealer inventory.
