## Tools (3)

- `get_window_sticker`: 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, no key.
- `which_makes_are_covered`: 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.
- `why_no_sticker`: 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).
