Deciphering Yahoo's request requirements

[Eeets]

This resource is incredibly useful - thank you so much for working on it.
I'm curious about how you decipher some of yahoos requirements when submitting requests. For example, when trying to get player stats for a previous season:
https://fantasysports.yahooapis.com/fantasy/v2/league/{league_code}/players;position=G;start=0/stats;season=2018
doesn't seem to work but adding "type=season" to the request as you have done in your player_stats api works perfectly.
https://fantasysports.yahooapis.com/fantasy/v2/league/{league_code}/players;position=G;start=0/stats;type=season;season=2018

How do you know to do this? I've looked through the api documentation and although it's helpful 'enough' it certainly doesn't explain things in this level of detail.

I discovered a few APIs by trial-and-error. But there was some data that I was not able to find the APIs for (e.g. Yahoo! predictions). I agree the their documentation was lacking in detail.
