Hey Matthew, we unfortunately don't track percent ownership by day. Technically, we do have it by week, but we didn't have a way to access that. Hm.
I just coded it up and added it in, though, so if you need to get percent_owned data by week, you'll be able to as of about two weeks from now by making requests like:
http://fantasysports.yahooapis.com/fantasy/v2/player/<player_key>/percent_owned;type=week;week=<week>
Note that percent_started is also an interesting resource, and that one is accessible by date.

Wanted to include what I am trying:
http://fantasysports.yahooapis.com/fantasy/v2/player/%s/percent_owned;type=date;date=2011-09-09
The return value includes:
( [coverage_type] => season [value] => 86 )
Always seems to be season.

Is it possible to get historical ownership by day? I'd like to specify a date for a percent_owned on a player to see how their ownership has changed. Hoping there is a way. I've tried the obvious (adding a date to the query).
Thanks.
