🚀 Quick Start Examples
// Kelley Blue Book API Example
const response = await fetch('http://developer.kbb.com/#!/data/1-Default', {
method: 'GET',
headers: {
'Content-Type': 'application/json'
}
});
const data = await response.json();
console.log(data);Getting started with the Kelley Blue Book API
If you're looking to get information about cars, you might want to check out the Kelley Blue Book API. KBB is a widely-used car valuation and information service in the US. By making use of their public API, you can access this information programmatically.
How to Get a Kelley Blue Book API Key
There is no free, self-service Kelley Blue Book API key. KBB does not offer public developer signup for its vehicle-valuation data — the developer.kbb.com portal exposes only B2B products (such as IDWS 4.0 and Batch VIN) that require a commercial agreement with KBB / Cox Automotive.
To get access:
- Go to https://developer.kbb.com and use the Contact Us / B2B solutions link.
- Describe your use case; KBB provisions credentials for approved partners (typically dealers, lenders, and automotive businesses).
- There is no published free tier or instant key — pricing and terms are negotiated per partnership.
If you only need vehicle data for a small or non-commercial project, consider open-signup alternatives such as the NHTSA vPIC API (free, no key, VIN decoding at https://vpic.nhtsa.dot.gov/api/) for specifications, or commercial valuation providers with self-service keys. For official KBB values without an API, the consumer site at kbb.com is free to use. In short: the KBB API exists but is partner-only, so budget for a sales conversation rather than a quick key signup.
Accessing the API
Retrieving the current year make model data
fetch(`http://api.kbb.com/v1/vehicle/makeModelYear?year=current&state=USED&utm_campaign=certifiedpreowned&utm_medium=display&utm_source=hanckelroadbannerad&utm_content=survey`, {
headers:{
'Authorization': `Bearer ${apiKey}`
}
})
.then(response => response.json())
.then(data => console.log(data))
.catch(error => console.log(error))
This code retrieves the current year make model data for used cars.
Retrieving value range for a given year, make and model
fetch(`http://api.kbb.com/v1/vehicle/value/${year}/${make}/${model}/condition/${condition}?mileage=${mileage}&zipcode=${zip}`, {
headers:{
'Authorization': `Bearer ${apiKey}`
}
})
.then(response => response.json())
.then(data => console.log(data))
.catch(error => console.log(error))
This code retrieves the value range for a given year, make and model of a car, for a specific mileage and zip code.
Retrieving specific vehicle data
fetch(`http://api.kbb.com/v1/vehicle/${vin}`, {
headers:{
'Authorization': `Bearer ${apiKey}`
}
})
.then(response => response.json())
.then(data => console.log(data))
.catch(error => console.log(error))
This code retrieves a specific vehicle data by its VIN number.
Conclusion
The Kelley Blue Book API is an extremely useful tool for developers looking to access information about cars in the US. By following the examples in this post, you can easily get started with the KBB API and start building your own applications.
