FreeCNAM
A free CNAM resource and API
We wanted to provide the community with a free and simple way to access telcom CNAM data, so we've launched this resource.
Using this free API is simple: Just make a normal (GET) request to https://freecnam.org/dip with a phone number set to the "q" query parameter
Example:
The response to this request is a standard 15-character CNAM result.
https://freecnam.org/dip?q=2021112222 The response to this request is a standard 15-character CNAM result.
It is really as simple as that.
Since this is a free community service, there are common sense rate limits to prevent abuse.
