D&D Beyond has the full basic rules and SRD which provides all the rules you need to play, all the base classes with a subclass each, all the base races with one subrace where applicable, and all unearthed arcana (plus blood hunter and gunslinger). With the Eberron book, you actually have access to all the base classes and four additional races. You can also use all the tools.
I was awarded a code for the Eberon source book but I already own that sourcebook on D&D Beyond. Can I exchange this code for a different book?

Hi there,
unfortunately not - any such giveaways are for specific books.
I recommend finding a friend who might appreciate receiving the book. 😊

Pity. Might have gotten me to actually use the platform.
Thanks so much for the quick response!

But... You have content on DDB, why not use the platform for that?
Without at least the phb it's rated useless
