Edmunds API vs NHTSA vPIC for AI agents
Edmunds API is Edmunds' former open developer API; access is now limited to selected partners and to dealers through a dealership program. 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
- Edmunds API: Not available to new developers; only existing Edmunds partners and dealers can use it.
- NHTSA vPIC: Free, keyless VIN decoding to identify a vehicle's make, model, year and specs.
