Vehicle Market Value API
The vehicle market value API estimates the market value for used and new cars by VIN based on millions of historical vehicle sales stored in VinAudit’s sales database. With the assumption that sale prices are normally distributed, VinAudit’s market value model estimates the “below market” and “above market” values within a distribution. Access to the vehicle market value API requires an API account with market value access enabled.
