Overview
Kelley Blue Book (KBB) is one of America's most trusted vehicle valuation services, and its API gives access to car pricing, configurations, and detailed vehicle data. It is widely used in automotive dealership software, insurance tools, and car-buying platforms. Access requires applying for API credentials through the KBB developer portal.
Beginner Tip
KBB API access is not self-serve — you need to apply and be approved at developer.kbb.com. While waiting for approval, explore their documentation to understand the pricing models (trade-in value vs. retail value) so you can choose the right endpoint for your use case.
