The vehicle stack, endpoint by endpoint.

10 focused product surfaces are being shaped into one consistent contract. Every endpoint below is a preview, not a claim of current availability.

Vehicle Report API

Generate a coverage-checked Vehicles.dev report assembled from vehicle, market, safety and ownership data. Use GET /v1/reports/quote for a free coverage check before report generation.

GET /v1/reports/{vin}Per report

02 / Methodology

Trace the answer, not just the number.

The planned contract keeps observed facts, normalized records, and derived estimates distinct. That gives developers the context to decide where each answer belongs in their product.

Input
Source observations
Preserve when and where a listing, specification, or safety record was observed.
Shape
Normalized vehicle records
Resolve identifiers and units without erasing useful nulls or source timing.
Model
Versioned intelligence
Return valuation and depreciation assumptions beside the model version used.
Output
Coverage-aware responses
Expose the geography, mileage, horizon, and observation window behind an output.

03 / Pricing model

Start free. Pay for what your product uses.

A platform tier sets access and throughput. Transparent usage rates cover the data work. The premium Vehicle Report API is metered separately from standard API calls.

Planned launch pricingNo charges begin until your API key is enabled and pricing and coverage are confirmed with you.

04 / Questions

The useful details, up front.

The catalog is in early access. These answers describe the product contract we are building, not operational endpoint guarantees.

01Can I see where a value came from?

Each response is designed to carry observation time, model or dataset version, and the coverage details needed to judge it.

02How do listing and valuation data relate?

Listings are normalized into our own observation model. Value and depreciation outputs are derived products with versioned assumptions, not copied source records.

03Are vehicle reports included in API quotas?

No. Vehicle Report API is available on Pro and Scale and billed per successfully generated report at the tier rate. Coverage checks are free, unsupported VINs cost $0, and failed generations cost $0. Reports never consume standard API call quota.

04What counts as a billable API call?

Only responses that successfully complete the requested lookup are billed. Authentication failures, rate-limit rejections and server errors are not billable.

05Can I resell or redistribute the data?

Standard plans cover use inside your product, not redistribution of raw records or resale as a standalone dataset. Bulk and redistribution rights require a separate agreement.

06Which APIs are available today?

The catalog and launch rates are previews. We will confirm final pricing, coverage and release status before enabling a billable API key.
