Is that the entire xpub? It seems too short. Also, I can't get it to validate. – Nick ODell – 2017-03-15T16:16:37.517

so here you are not for answer you only want to test xpub ? , i asked how to do this on bitcoin core without any api , so what ???? – Terry Higgins – 2017-03-16T07:17:32.780

1I think the reason that you're having trouble is that the xpub isn't valid. That means that you'll have trouble no matter what library you use. – Nick ODell – 2017-03-16T16:20:11.837
