Vincario Vehicle Info API

  title: Vincario VIN Decoder Account Vehicle Info API
  description: 'REST API for the vindecoder.eu service operated by Vincario. The API decodes a Vehicle Identification Number (VIN) into a full vehicle specification and also provides vehicle market value, real-time stolen-vehicle checks, the list of decodable vehicle details, and the remaining account balance.


    Authentication uses an API key (id) and a secret key. Each request carries a per-request control sum in the URL path. The control sum is the first 10 characters of the SHA1 hash of the pipe-delimited string `{lookup}|{id}|{apikey}|{secretkey}`, where `{lookup}` is the uppercased VIN for VIN-based endpoints (decode, vininfo, vehicle-market-value, stolencheck) and the API key itself for the balance endpoint, and `{id}` is the endpoint identifier (for example `decode`, `vininfo`, `vehicle-market-value`, `stolencheck`, `balance`). The secret key is never transmitted; it is only used to derive the control sum. The path layout is `/{apikey}/{controlsum}/{id}/{vin}.json`.'

      description: Path-signed authentication. The API key (id) and a per-request SHA1 control sum are passed as URL path segments rather than headers or query parameters; this scheme is declared as a placeholder because OpenAPI 3.0 cannot natively express path-segment-based signed credentials. The control sum is `substr(sha1("{lookup}|{id}|{apikey}|{secretkey}"), 0, 10)`. The secret key is never sent over the wire.
