BirdsiteLIVE status - is it a dead project or... ???

So, somehow I got lost in the internet woods and came across birdsiteLIVE - which is basically a bot that makes twitter accounts viewable on the fediverse with activitypub(it's one way unfortunately, so twitter accounts won't see any replies or anything like that).

So I did some digging to give it a try, and after some time I arrived at the conclusion that mastodon.social, the instance I have an account on and the largest instance, doesn't seem to have any active or useful birdsitelive servers federated. But this is based on searching for mirrored twitter accounts - I haven't yet figured out how to see which servers mastodon.social has federated. So if someone could point me in the right way there that would be helpful.

I know there was the big API price hike(just like reddit) in february and maybe that killed off many of the birdsitelive instances. But it seems like some are also still running? It looks like the official beta instance is dead https://mastodon.social/@BirdsiteLIVE@fosstodon.org/109299139482179395

The last release on github was on march 16th.

I guess... what's the deal? how are the servers that are running, running despite the API switch? I guess I do not want to suggest birdsitelive to people unless there's some expectation it can keep working in reasonable capacity I suppose. It seems like a highly useful tool.
