The VinLINK system is a standard HTTP POST protocol.
- Open TCP/IP connection to VinLINK server.
- Send request formatted as an HTTP POST (RFC 2616, see http://www.faqs.org/rfcs/rfc2616.html).
(for example: http://service.vinlink.com/report?type=basic&vin=1FMCUo4112KA7126 )
- The VinLINK server will access vehicle data, format it as XML, output the information through the same TCP/IP connection and close the connection.
The information is sent as a standard HTTP reply, with content set to "text/xml".
- Reads the information and close your side of the TCP/IP connection.
Meanwhile, one of their competitors says:
You will find that using the decoder web service is as simple as making an HTTP request.
Using REST/XML you should be able to implement within 1 hour.
Two similar services. Two very different explanations.

Hey Dan, are either of these services “free” or are they charging per decoded VIN? Glad to see your new blog.

They all charge, usually per decoded VIN. I don’t remember exactly off the top of my head, but it starts around 20¢/decode and drops with volume.
