We would be interested in re-selling your address verification services as an add-on to our product. Could you send us info about your API so we could test the interface?
Absolutely. You'll need to create an account and then create an authentication token and you're ready to go. On the bottom of the keys page (in the Test Driver area) you'll see a fully functional example url using your authentication token. Take a look at that as it will show you how to construct a request. Then look at our documentation. That should get you up and running.
