When buying a car—new or used—knowing exactly what you’re getting is essential. One of the most effective tools for ensuring transparency is the window sticker. Also called a Monroney label, a window sticker is a legally required label displayed on new cars, detailing critical information such as price, features, and performance ratings. Through tools like the window stickers API or vehicle features API, both buyers and sellers gain access to key data points that support a transparent and trustworthy buying experience.

What is a Window Sticker?

A window sticker is essentially a vehicle’s “ID card,” giving a complete picture of its features and specs. By using a window sticker by VIN, buyers can view essential vehicle details directly through the Vehicle Identification Number. Each sticker includes:

• Manufacturer’s Suggested Retail Price (MSRP): The starting price suggested by the manufacturer.
• Vehicle Specifications: Core details on engine, transmission, fuel type, drivetrain, and other major features, often accessible via a vehicle features API.
• Standard and Optional Equipment: A comprehensive list of standard features along with any added packages, retrievable through vehicle options data for more accurate representation.
• Fuel Economy: Estimated miles per gallon (MPG) for city and highway driving to help buyers understand fuel costs.
• Safety Ratings: Crash test scores from the National Highway Traffic Safety Administration (NHTSA).
• Warranty Details: Information on warranty coverage provided by the manufacturer.
