Pressing FAV icon on a cache selected on LIVE MAP page shows list of cachenames who Favorites this cache.
The GroundSpeak API does not support this feature. There is no way for me to query this data.
So unfortunately this is a no-go.
is it possible to get the data from GCVOTE?
Nope, GCVOTE has nothing to do with favorites on gc.com. 2 different things...
Cache GCD has 782 Favorites right now and GCVote reports 4.45 stars from 10 votes.
And yes, in general that data can be accessed but I personally don't care for it and will not support a random voting website that clearly never caught on (see cache GCD and it's numbers).
