Window Sticker API: Fetch & Parse Original Monroneys by VIN
Two honest facts define this category. One: for 12 brands — GM's four, Ford/Lincoln, Stellantis' four, Hyundai and Genesis — the original factory window sticker is retrievable by VIN, live from the manufacturer source, and an API can hand it to you as the real PDF or parsed into JSON with every option priced. Two: for Toyota, Honda, and most import brands, no provider can fetch the original, because those OEMs publish no public sticker endpoint — any "all brands" claim is a reconstruction, not the document.

Fetch the original PDF
# The original factory PDF by VIN curl -H "x-api-key: YOUR_KEY" -o sticker.pdf \ "https://www.carwhere.com/api/dealer/v1/window-sticker?vin=1GTPHGE80TZ138393" # Or availability-check first (JSON, costs one call): curl -H "x-api-key: YOUR_KEY" \ "https://www.carwhere.com/api/dealer/v1/window-sticker?vin=1GTPHGE80TZ138393&format=check"
Or get it as data: the parse endpoint
The part no other API offers. One call fetches the sticker and reads it — pricing block, itemized factory options, colors, powertrain — with a confidence grade computed by reconciling the option prices against the printed options total. A parse counts as 5 calls; a VIN we can't fetch or a document we can't read is never charged.
# Fetch AND parse in one call — the sticker as data, not a PDF
curl -H "x-api-key: YOUR_KEY" \

Generally 2016-and-newer vehicles sold through US dealers; availability is per-VIN and the check endpoint answers it definitively. Toyota, Honda, Subaru, Nissan, and European brands publish no public sticker endpoint — unavailable from every provider, us included.

FAQ
Is there an API for window stickers?
Yes. CarWhere's developer API fetches the original factory window sticker (Monroney label) by VIN for 12 brands — Chevrolet, GMC, Buick, Cadillac, Ford, Lincoln, Chrysler, Dodge, Jeep, Ram, Hyundai, and Genesis — as the manufacturer's own PDF, and can also parse it into structured JSON (MSRP, destination charge, itemized options). $49/month for 1,000 calls, 7-day free trial.
Can an API get Toyota, Honda, or Subaru window stickers?
No — and this is true for every provider, not just us. Those manufacturers do not publish a public per-VIN sticker endpoint, so there is nothing for any API to fetch. A vendor claiming "all brands" is reconstructing an approximation from decode + spec data, which is not the original factory document and will not show the actual options or original MSRP of a specific car.
What is a parsed window sticker? Why not just the PDF?
The PDF is an image of a document; most applications need the numbers. The parse-sticker endpoint returns the pricing block (base MSRP, destination charge, total MSRP) and every factory option line with its price as JSON, plus colors, engine, and transmission. Each response carries a confidence grade — "high" means the itemized options arithmetically reconcile with the printed options total.
How far back do window stickers go?
Manufacturer sticker systems generally cover roughly 2016-and-newer vehicles sold through US dealers, with coverage thinning for older model years — the originals predate the OEMs' digital records. Availability is per-VIN; the check endpoint answers it definitively for a specific car, and VINs we can't retrieve are never charged.
Is a window sticker the same as a build sheet?
They overlap but differ: the Monroney (window sticker) is the federally mandated consumer price label — MSRP, options with prices, fuel economy, assembly plant. A build sheet is the factory's internal production record (RPO/option codes, paint codes). For "what did this car come with and what did it cost new," the sticker is the document you want, and the one retrievable by VIN.
What do people build with a window sticker API?
Appraisal and diminished-value tools (original MSRP + options = loss basis), dealer websites and listing enrichment ("original MSRP $72,055" sells), lease-buyout and equity calculators, classic/CPO verification ("is this really a Denali with the Technology Package?"), and AI agents answering "what options does this VIN have."
