Kelley Blue Book
Kelley Blue Book's Cox Automotive-run API program (IDWS, Advertising Data, Instant Cash Offer, and Batch VIN) provides vehicle valuation, pricing, and configuration data behind an approval-gated API key, per developer.kbb.com's own access instructions. Its legacy Swagger doc-viewer content pages (/content/data/*.html) now 404 into the site's SPA shell — orphaned — but the surrounding portal, the key-request process, and Cox Automotive's successor developer platforms (developer.coxautoinc.com, coxautoinc.mashery.com) all remain live over HTTPS, confirming https true and that the program has moved rather than gone dead; cors could not be re-probed live since no public endpoint or key is available. Access requires Cox Automotive approval with no public self-serve signup — paid.

- Sign up with the provider to get an API key.
- Send it on every request as a header
Authorization: <key> - The exact header isn't documented — Authorization is a common default; confirm in the provider's docs.
Your key is stored only in this browser (localStorage) and sent directly to the API — never to greatapis.
