Randall,
This looks remarkably easy to use. Just a small tip: On opencname's home page, you suggest users try the following API call:
$ curl https://api.opencnam.com/v1/phone/2024561111
US GOVERNMENT
I tried it and received a different result: $ curl https://api.opencnam.com/v1/phone/2024561111
DIST OF COLUMBI
Perhaps you should update your home page to reflect this?
