I am trying to use the fantasysports collection API to get a list of players and their stats by season and week number.
https://fantasysports.yahooapis.com/fantasy/v2/players;player_keys=380.p.29236,380.p.28429,380.p.27619,380.p.31074,380.p.26822,380.p.24045,380.p.29370,380.p.6243,380.p.100003,380.p.8780,380.p.31144,380.p.26650,380.p.29384,380.p.24815,380.p.27789,380.p.8447/stats;type=week;week=1?format=json"

but for every player the stat values are 0:
{
"stat": {
"stat_id": "3",
"value": 0
}
},

How can I use the player collection to get a list of players stats by a week number??
