Automotive data API
Identification, specifications, valuation, depreciation, ownership costs and marketplace listings behind one REST API and one key.
Valuations come from live marketplace listings rather than a licensed pricing book, so they reflect what comparable cars are actually being advertised for.
Endpoints this uses
| Endpoint | Path | What it contributes |
|---|---|---|
| VIN Decode | GET /v1/vehicles/vin/{vin} | Identify the vehicle. |
| Market Value | GET /v1/vehicles/market-value | Price it against live marketplace supply. |
| Depreciation | GET /v1/vehicles/depreciation | Project how that price decays. |
| Ownership Costs | GET /v1/vehicles/ownership-costs | Project what it costs to run. |
Market-derived, not book value
Valuation is derived from current marketplace listings for comparable vehicles, so the number moves when the market moves.
That is a different thing from a book value, and it is worth being explicit about which one your application needs: asking prices lead transaction prices, and the gap between them widens in a volatile market.
Pricing
The free Starter plan includes 1,000 calls a month shared across all eleven synchronous vehicle data APIs, plus $10 of one-time credit for usage after that allowance.
Credits never expire and are spent per successful call.
Every endpoint needs an API key; there is no unauthenticated tier.
Frequently asked questions
- Where does the pricing data come from?
- Valuation and depreciation are computed from live marketplace listings — current asking prices for comparable vehicles — rather than from a licensed book value.
- Can I get everything in one call?
- No single response combines every data product. Compose the explicit VIN decode, valuation, depreciation, ownership, and report operations your workflow actually needs.
