Original factory window stickers (Monroney labels) by VIN for 20 makes, plus an NHTSA spec decode.
Scored across 3 tools
Each tool serves a clearly distinct intent: one performs a VIN lookup, one enumerates covered makes/model years, and one explains a negative result. There is no realistic scenario where an agent would confuse which tool to call.
All names use consistent snake_case, which is good. The verb styles vary slightly (imperative get_ vs. interrogative which_/why_), but the semantics are transparent and readable, so this is a minor deviation rather than a real inconsistency.
Three tools is on the thin side, but the server's scope is a single narrow lookup service, so each tool earns its place. Two of the three are meta/explanation tools rather than core operations, which is justified by the domain but keeps it from being a perfect fit.
For a read-only lookup service, the surface covers the main query, the coverage map, and the failure explanation, leaving no obvious dead end. Minor gaps exist (no batch lookup or VIN validation helper), but agents can work around these easily.
Look up the original factory window sticker (Monroney label) for a 17-character VIN, with an NHTSA specification decode. Returns links, never the PDF itself: page is the result page to give a person, and pdf is the label when one exists. For Toyota, Lexus, Nissan and Infiniti it returns only labels we already hold. Free. A key is optional and raises the daily limit.
Inputs: vin (required). Returns: vin, vehicle, warning, windowSticker
The 20 makes that return an original factory window sticker, by source, with the model years each answers for and the last day it returned a label. Every other make gets a specification decode only.
Inputs: no named parameters. Returns: asOf, notes, sources, coverageUrl
Why a make, or a make and model year, has no window sticker here, and where to get one instead. Covers makes we get labels for (Ford only while a car is new, Toyota from 2025) and makes we don’t (Honda, Mazda, Tesla).
Inputs: make (required), model_year. Returns: make, steps, reason, source, +5 more
