Vincario (vincario.com, formerly vindecoder.eu) provides a REST API, currently version 3.2, that decodes a Vehicle Identification Number (VIN) into a vehicle specification and provides OEM VIN lookup, OEM service history, vehicle market value, stolen-vehicle checks, value lists (enums) for makes, models and other attributes, and the account credit balance. Requests are authenticated with an API key plus a control sum in the URL path. Vincario also runs a public MCP server (com.vincario/vehicle-data) and offers VIN OCR scanning and UK license plate lookup services, whose APIs are not yet publicly documented.
Vincario publishes 7 API contracts indexed on the APIs.io network, including VIN Decoder API, OEM VIN Lookup API, OEM Service History API, and 4 more. Tagged areas include VIN, Vehicle Data, Automotive, VIN Decoding, and Market Value.
Vincario’s developer surface includes authentication, documentation, API reference, engineering blog, and 11 more developer resources.
Regulatory Posture applies to this provider. Its tags matched the
Horizontal (data, software, accessibility, platform) regime, so
Regulatory Posture carries 15 points of the composite.
If this regime is wrong for your business, say so on your
provider repo — the
applicability map is public and we will correct it.
Create-or-Update Ergonomics does not apply to this provider. The published contracts declare
no write operations, and a read-only API cannot create-or-update. The facet is excluded from this provider's
denominator entirely — not scored zero. A reference or data API is not deficient for being unable to
upsert.
The six quality facets above are damped to 85 points between them,
because the conditional facet above carries the other
15. That is why each facet's contribution is shown against a damped
maximum: raising a quality facet moves the composite by 85% of its nominal
weight, not 100%. The full arithmetic is at apis.io/rating/.

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/vincario: open an issue to ask a question, or submit a pull request to add artifacts.

Markets this provider is in provisional
The Kin Score Market layer reads a provider inside its market:
its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted:
not part of the Kin Score or agent readiness.
Registered MCP server and declares compatibility are report only — not weighted.
Undeclared means we found nothing we can read, so there is no number: we never infer integrations.
Discovery needs no key. Ratings and market analysis are Pro.
