Manheim Data Parser & API

Manheim is Cox Automotive’s wholesale auction network — the largest dealer-to-dealer auction channel in the US, moving a very large B2B volume — and Carapis extracts its per-lot data, including VIN, condition grade, announcements and sale history, through one REST API. Manheim is dealer-gated (login-only) with little public traffic, but its structured wholesale data is among the most valuable in North America for pricing intelligence — delivered without you managing dealer-only access yourself.

What is Manheim?

Manheim is the largest physical and digital wholesale vehicle auction operator in the US, part of Cox Automotive. It is a B2B channel: licensed dealers buy and sell used vehicles, including off-lease and fleet cars, through Manheim’s physical lanes and online platforms. Because it is dealer-gated behind a login, it has low public traffic but a very large transaction volume — and each lot carries a structured Manheim condition grade, announcements and sale data.

Market Position

Manheim is the leading US wholesale dealer-auction channel; together with Copart, IAA and OPENLANE, the US wholesale auctions move well over 800K vehicles per week. As part of Cox Automotive, it shares ownership with AutoTrader.com and Kelley Blue Book (KBB) — so one Cox cluster spans retail listings (Autotrader/KBB) and the wholesale side (Manheim). Manheim’s condition grades and Manheim Market Report values are an industry-standard wholesale-pricing reference, making it uniquely valuable for residual-value and remarketing models.

Data Fields Available

Carapis extracts a complete structured record from each Manheim lot:

• Vehicle identity — make, model, trim, model year, VIN
• Condition — mileage, Manheim condition grade, damage/announcements, run condition
• Sale data — sale / bid history and channel
• Listing context — auction location, photo gallery

The condition grade, announcements and wholesale sale data are the standout fields — a structured wholesale-pricing signal not visible on retail portals.
