A REST VIN decoder API that decodes 17-character VINs against official OEM catalogs (not scraped), validates the check digit with the ISO 3779 formula and returns make, model, year, assembly plant and SSPL supersessions — ready for your ERP, CRM or AI agent.
Free VIN APIs like NHTSA vPIC are fine to identify a vehicle sold in the US, but they don't return the OEM part number, don't validate SSPL supersessions and poorly cover Latin American assembly plants. Selling parts without returns requires more: a VIN decoder API wired into the manufacturer's official Electronic Parts Catalog.
Our VIN decoder API is the same technical layer that powers AutoParts AI Agent inside dealerships across Mexico, Colombia, Argentina, Chile, Peru and the Dominican Republic. We expose it as an authenticated REST endpoint so your team can integrate it directly in your ERP, internal app or your own AI agent.
P50 latency under 150 ms, P95 under 400 ms. Enterprise 99.9% SLA. OpenAPI 3.1 documentation, TypeScript and Python SDKs and dedicated technical support.
More than a generic decoder — an API built for selling auto parts.
Applies the position-9 verification formula and rejects malformed VINs before spending a catalog call.
WMI (1–3), VDS (4–9) and VIS (10–17). Returns make, model, body, engine, model year and assembly plant.
Authenticated calls to Toyota TIS, Nissan FAST, Honda iN, Suzuki, JLR Topix and more. Returns OEM part numbers, not guesses.
Cross-checks the requested part against the OEM's live SSPL table and returns the current part number, not the legacy one.
Consistent schema across OEMs. Your ERP integrates once and supports new brands without touching code.
10,000 req/min by default, scalable under SLA. No surprises during end-of-month demand spikes.
Three HTTP calls and your system quotes parts like a factory-authorized dealer.
Send the VIN. The API validates format, check digit and rejects invalid VINs before spending OEM catalog quota.
Returns the structured JSON: WMI, VDS, VIS, make, model, year, engine, plant, country of assembly and destination market.
With the decoded VIN and a part category, returns OEM part numbers, live SSPL supersessions and the exploded diagram when available.
The technical detail that separates identifying a vehicle from quoting the right part.
We give you sandbox access and a sample VIN decoded against the official EPC. No card, no commitment.
No proprietary SDK, no lock-in. Plain REST, normalized JSON across OEMs.
