Guild Kdr API status

[wanted.6214]

Hello :) ,

I tried to use the Guild Kdr API following the examples on GitHub https://github.com/arenanet/api-cdi/blob/master/v2/wvw/guild-kdrs.js and here https://wiki.guildwars2.com/wiki/API:2/wvw/matches/stats:id/teams but nothing work, API return empty brackets or "no data for guild".

An example here: https://api.guildwars2.com/v2/wvw/matches/stats/2-2/guilds/C6C321F7-BC44-4F09-A865-F8C5514A123D

I posted here for asking if these API are enabled or not?

Thanks. :)
