Kelley Blue Book (KBB) Data Parser & API

Kelley Blue Book is the US car-valuation authority — around 20M visits per month — and Carapis extracts 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.

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.

Data Fields Available

Carapis extracts a complete structured record from KBB:

• Vehicle identity — make, model, trim, model year, VIN
• Condition — mileage and condition tier
• Valuation — KBB trade-in, private-party and retail price bands (the standout field)
• Pricing — dealer listing price (via the Cox/Autotrader feed)
• Specification — factory options and trim packages
• Listing context — dealer name / location, photo gallery

The KBB valuation bands are the unique asset here — a ready-made pricing-signal layer for residual-value and appraisal models.
