The description inside: http://www.tvmaze.com/api#season-episodes
--------
A list of episodes in this season. Specials are always included in this list; they can be recognized by a NULL value for number.
URL:/seasons/:id/episodes
Example: http://api.tvmaze.com/seasons/1/episodes

The API would benefit from specifying further which ID it expects. (In this case, it was the season ID)
The only reason I bring this up, is because this specific example made me run a few laps before figuring which ID it wanted. Now, after learning which ID it uses - it is obvious. Of course, it was not obvious until I realized that - a process that could be hastened by adding :id-season/episodes, or equivalent descriptions to the parameters.
