Is there any way to add a free one or does it only work by subscription?
I want my website visitors to have access to information about Bitcoin ATMs around the world.
The only information I've found is about "custom integration"
Custom map integration for your website
We provide an iframe integration of bitcoin ATM map for particular operator's locations as a subscription service.
I guess that best would be e-mail them (
support@coinatmradar.com) and ask.
And if the answers you get are not what you'd like (i.e. if it's a paid service), you can look for the (few) competitors, maybe you get lucky.
