Can I get US used-car data via API?

Yes. Carapis returns structured listings from CarGurus, Cars.com, AutoTrader.com, CarMax and Carvana — make, model, year, mileage, price, VIN and dealer info — through one REST API, so you do not have to build separate US scrapers.

What are the biggest car sites in the United States?

By traffic, CarGurus leads (~36M/mo), followed by AutoTrader.com (~26-28M) and Cars.com (~27M). CarMax and Carvana dominate online-only used-car retail.

Can I get US auction and salvage car data?

Yes — Carapis also covers Copart and IAA, the two largest US vehicle auctions, which exporters and remarketers use for salvage and wholesale inventory.

How current is the United States data?

Listings are refreshed on an ongoing basis so prices, status and inventory stay close to live. See the pricing page for refresh tiers.
