Year Make Model Options
Populate Year, Make, Model, and Variant dropdown menus. Each response returns exactly one layer. dimension is optional — when omitted, the response shape is inferred from make/model/year. Billing: most calls cost 1 unit. dimension=variants with year + make (no model) costs 1 unit per model; the response includes modelCount. Required filters help you get better, more relevant results. year, make, and model can be combined for reversed lookups (e.g. years for a given make+model).
Query parameters
Return exactly this array when required filters are present. If omitted, the response is inferred automatically from make/model/year.
Filter to a specific manufacturing year. Required when filtering by model without make.
Filter to a specific manufacturer (e.g., Toyota, Ford, Lexus). Required for dimension=models.
Filter to a specific model (e.g., Camry, F-150, LX). Required for dimension=trims and for dimension=variants unless both year and make are set.
Optional substring filter on trim names. Only applied when querying dimension=trims or dimension=variants.
Response
Distinct values for the requested (or inferred) dimension(s).
