Kelley Blue Book (KBB) Data Parser & API
Kelley Blue Book is the US car-valuation authority — around 20M visits per month — and Carapis can extract both its KBB valuation bands and its dealer listings through one REST API. Owned by Cox Automotive, KBB serves its listings off the AutoTrader.com inventory feed, so a single parsing strategy covers both — and its trade-in, private-party and retail price bands add a unique pricing-signal layer on top of raw listings, delivered without you building or maintaining an Akamai-protected scraper.
On request — not in the live feed today. We do not continuously crawl Kelley Blue Book (KBB) right now. Activation takes 2–3 weeks of engineering and is quoted per source, because each one ships with dedicated proxies, anti-bot tuning and ongoing maintenance. Ask us to add it.

What is Kelley Blue Book?
Kelley Blue Book (KBB.com) is the best-known US vehicle-valuation brand, owned by Cox Automotive. It draws roughly 20M visits per month (Semrush, Apr 2026) and is unique among major US sites for publishing structured valuation bands — trade-in, private-party and retail price ranges by make/model/year/trim/mileage — alongside dealer listings that are served from the same Autotrader inventory feed.
Market Position
KBB attracts ~20M visits per month (Semrush, Apr 2026), making it one of the most-visited US automotive sites. As part of Cox Automotive, it shares an inventory backend with AutoTrader.com, and sits in the same cluster as the Manheim wholesale network — so the Cox listings reachable through KBB largely overlap with Autotrader. Its distinctive value is the valuation layer: the KBB price bands are a market-pricing reference that complements listing data from CarGurus, Cars.com and others.
What the API returns
Response schema
Indicative — this is the shape, not a guarantee. Every source returns the same structure, so what you build against does not change when you add one. Which fields carry a value depends on the source and on the individual listing: a site that does not publish mileage returns null there, and Kelley Blue Book (KBB) is no exception.
List — GET /apix/api/vehicles/ — returns 30 fields per vehicle:
