  title: CarGurus Developer APIs Car Selector API
  description: 'Documented HTTP APIs published by CarGurus under the /Cars/api/ path. Four surfaces are described here: the open (no-auth) Car Selector API for building new/used listing search widgets, and three partner/dealer-gated APIs - Instant Market Value (IMV), Dealer Reviews, and Dealer Stats. The gated APIs authenticate with an appId and authToken issued by CarGurus and are passed as query parameters alongside a JSON body. Endpoint paths, methods, and the Car Selector, IMV, and Dealer Reviews schemas are taken directly from CarGurus developer documentation; the Dealer Stats response is modeled from CarGurus documentation and published examples (endpointsModeled). CarGurus does not publish a public inventory-listings pull API - dealer inventory is ingested via inventory feeds (feed providers / IMT) - and leads are delivered to dealer CRMs rather than exposed here.'
