Some suggestions as the API is in my opinion not complete:

• Get all races of a season so that you have the complete schedule. Not possible at the moment as competition id is required.

• Get all drivers of a season. You can not search on driver who are active in season 2021.

-Like to Driver object has an array with teams, the Team object should have an array with Driver per season.

• Split complete name of driver in firstname and lastname, so that you sort or order on driver lastname in your own project.

I have got also some property ideas for the different objects but i think the points above are absolutely an added value to your API.
