CarAPI gives developers a single REST API for vehicle makes, models, trims, VIN decoding, and OBD-II codes. See 2026 pricing plans and how it compares.
CarAPI's core value proposition is consolidation: instead of stitching together separate data sources for vehicle specifications, VIN decoding, and diagnostic codes, developers get one authenticated REST API covering all of it. The year, make, and model layer spans a very wide historical range, while more detailed trim, submodel, engine, body, color, and mileage data is available from roughly the 1990 model year forward through current and near-future model years. VIN decoding takes a 17-character vehicle identification number and returns structured attributes, letting applications auto-fill vehicle details from a VIN rather than requiring manual entry, and a companion license-plate-to-VIN lookup extends that convenience further upstream. The OBD-II diagnostic code database, covering more than 9,000 codes, serves a different but related audience: repair shops, telematics platforms, and fleet management tools that need to translate a diagnostic trouble code into a human-readable description.
This breadth is what differentiates CarAPI from narrower competitors that focus on just VIN decoding or just a makes-and-models catalog. It also explains the plan structure: rather than gating by feature category alone, CarAPI primarily gates by daily call volume, with the higher tiers unlocking progressively deeper data (submodels on Plus, full trim and specification depth on Premium) alongside higher rate limits, so the right plan depends as much on how much data depth an application needs as on its request volume.
CarAPI's pricing is unusually transparent for a data API: all three tiers and their exact daily call limits are published on its website rather than gated behind a sales call. Base, at 199 dollars a year, is aimed at developers prototyping or running lower-volume applications who mainly need core year/make/model and VIN decoding. Plus and Premium, at 249 and 299 dollars a year respectively, raise both the daily call ceiling and the depth of data available, with Premium unlocking the full specification set including engines, colors, and detailed trims. For teams that occasionally spike above their plan's daily limit, CarAPI offers metered overage billing rather than hard-blocking requests, which reduces the operational risk of an unexpected traffic spike breaking an integration.
Because CarAPI keeps a minimal public corporate footprint, with no disclosed founding date, headquarters, or team size, buyers evaluating it for a production system built around uptime-sensitive workflows, like real-time VIN decoding at a dealership point of sale, should treat it the way they would any smaller, specialized data vendor: verify current uptime history, support responsiveness, and data freshness directly before committing, since that operational detail isn't part of CarAPI's public marketing materials.
CarAPI provides vehicle makes, models, trims, body styles, engines, colors, mileage data, VIN decoding, license plate to VIN decoding, MSRP and market pricing, and a database of over 9,000 OBD-II diagnostic codes.
There is no permanently free production tier. Developers can prototype against a public dataset without an account, but live/production use requires one of the paid annual plans starting at 199 dollars per year.
As of 2026, CarAPI has three annual plans: Base at 199 dollars per year (1,500 calls/day), Plus at 249 dollars per year (3,000 calls/day), and Premium at 299 dollars per year (6,000 calls/day, full data depth).
CarAPI offers optional soft rate limiting with metered overage billing at roughly 0.001 dollars per call (about 1 dollar per 1,000 requests) rather than hard-blocking requests once the daily limit is reached.
