Notes
The KBB Developer Portal (developer.kbb.com) lists four APIs: IDWS 4.0, the Advertising Data API, the Instant Cash Offer (ICO) API and the Batch VIN API, with documentation and an account area. Kelley Blue Book is part of Cox Automotive, and the portal's contact is Cox Automotive's address in Irvine, CA. Access requires an account and approval from Cox. No MCP server is documented.
