Network Programming in .NET

Keeping your API relevant to your customers is something that makes can sometimes take your service in a directions that you never knew existed. This morning, I didn’t know what a CNIT number was, this afternoon, it looks like we’ve now got the only commercially available CNIT API available outside of the French government,

A CNIT number or “Code national d’identification du type“, has been used since 1998 and consists of 12 characters that can succinctly define the essential characteristics of a vehicle. For example: the fourth character defines the fuel type and transmission (0-9), the fifth defines the engine power (0-9), and the seventh code defines the body style (0-7). The CNIT is more general than the type Mines, but does not allow to know the level of equipment of a vehicle. Recently, the CNIT can contain 15 characters.

Our VIN lookup service now includes a JSON segment that contains the CNIT and TVV values of a car, in the following format

<Vehicle xmlns:xsi=”http://www.w3.org/2001/XMLSchema-instance“ xmlns:xsd=”http://www.w3.org/2001/XMLSchema“ xmlns=”http://regcheck.org.uk“>
