Can you buy roost on Coinbase?

Excuse me, I was wondering if you could clarify something for me. I've been reading about different cryptocurrencies and I came across the term "roost." Is it possible to purchase this particular cryptocurrency on the popular exchange platform, Coinbase? I've had success buying and selling other coins there, so I'm curious if "roost" is also an option. If not, could you recommend any other reliable exchanges or platforms where I might be able to acquire it? Thank you for your time and assistance.
