NHTSA vPIC API beginner's guide — what it is, how it works, when to use it
With any new API, the hardest part is figuring out what it actually does and where it's useful. Let's start there.
What is NHTSA vPIC API?
Official US Government API for every car in the world by VIN — free, no key.
NHTSA maintains vPIC — a database of every car ever built worldwide, by VIN. Free, no key, no declared rate limit. For a vehicle-check product in Israel, this is your global layer and pairs well with data.gov.il (Israel-specific).
Who it's for
- Vehicle-check apps
- Appraisers and tow companies
- Digital insurance
- Vehicle-value calculators
