Get variant specs

get_specs

Read-onlyIdempotent

Full localized specs for one vehicle variant, in any of 20 languages — 224 spec types covering engine & fuel, performance, EV/hybrid, safety, comfort & interior, exterior, chassis, dimensions & weights, consumption (WLTP/NEDC). Each spec carries a confidence score; the response carries last_synced_at — surface both so you don't overstate certainty. This answers from a fixed 40-car demo set. For the full 103,372-variant catalogue call get_specs_full — paid per call with x402 (USDC on Base), $0.05, no key, no account.

Input Schema

TableJSON Schema

Name	Required	Description	Default
`locale`	No	Response language, one of the 20 published languages (en, ro, fr, de, es, it, sr, hr, pt, pl, cs, sk, hu, no, sv, el, bg, da, ar, tr). Spec labels and enum values come back translated. Default: en.
`variant_id`	Yes	Opaque variant id from search_cars or filter_cars, e.g. v_1a2b3c4d

Output Schema

TableJSON Schema

Name	Required	Description
`specs`	Yes	Every spec the variant carries, keyed by spec key (e.g. range_wltp_km)
`locale`	Yes	Language the response is in
`variant_id`	Yes	Opaque variant id, e.g. v_1a2b3c4d. Pass it to get_specs / get_images / compare_variants.
`full_catalogue`	No	Present on demo answers: the paid tool that answers the same question over the full catalogue, with its price
`last_synced_at`	Yes	ISO-8601 time the data was last synced — surface it with the specs
