Hello Sergio, there is no free API version on Fanpage Karma. Please see the documentation on www.fanpagekarma.com/api/doc to test. For further questions, please always contact us at firstname.lastname@example.org
Hi Chris, API documentation is quite terse. I'm trying to do some tests within my own code, but the sample link you provide (www.fanpagekarma.com/api/v1/facebook/6815841748/kpi?token=abcdefghijklmnopqrstuvwxyz) does not work. It does not return the JSON file it should.
