CarGurus

CarGurus is an automotive shopping and dealer marketing platform that connects car shoppers with franchise and independent dealers through data-driven listings, its Instant Market Value (IMV) deal ratings, and dealer reviews. For developers and partners, CarGurus publishes a small set of documented HTTP APIs under /Cars/api/ - an open Car Selector API for building new/used search widgets, and partner/dealer-gated APIs for Instant Market Value, dealer reviews, and dealer performance statistics (leads, VDPs, SRPs, impressions). Dealer inventory itself is ingested through inventory feeds (feed providers / IMT), not a documented public pull API, and leads are delivered to dealer CRMs rather than exposed as a public REST endpoint.

CarGurus publishes 4 APIs on the APIs.io network, including Car Selector API, Dealer Reviews API, Dealer Stats API, and 1 more. Tagged areas include Automotive, Marketplace, Car Listings, Dealer, and Vehicle Pricing.

CarGurus’ developer surface includes documentation, signup flow, engineering blog, and 8 more developer resources.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/cargurus-dealer: open an issue to ask a question, or submit a pull request to add artifacts.
