eBay Browse API (vehicles) vs NHTSA vPIC for AI agents
eBay Browse API (vehicles) is eBay's Buy API for searching and reading eBay listings by keyword and category; the docs read today cover vehicle parts fitment but do not show a vehicle-specific listings guide. NHTSA vPIC is a free US government API that decodes VINs and lists makes, models and manufacturers; it has no listings or prices.
The short answer
- eBay Browse API (vehicles): Approved eBay partners who want eBay listings, including Motors, in their own app.
- NHTSA vPIC: Free, keyless VIN decoding to identify a vehicle's make, model, year and specs.
