Suggestion about queries

Hello I am new here,
I am playing around with the warcraft log classic API trying to do simple things such as display logs and check them in details ( this is something that warcraftlog is capable doing it, I just want to do this by my self for learning purposes ).

I have successfully completed the list of reports completed by my guild. Now I would like to get into more details such as Rankings for every encouter.

I found this query
[/rankings/character/{characterName}/{serverName}/{serverRegion}]

Problem is I can access it just from the characterName but I would like to get all the ranking for all the participant not just for 1.

Any other end point that can help me to achieve this ?

Thanks
