I had to do something similar for the search engine I'm working on. What I'm currently testing is indexing the api/v3/post/list endpoint and matching on the actor_id to the internal id. The only major problem with this is that I now need to crawl the entire fediverse in order to support all of the different sites.
Oh wow, that's also a huge undertaking! It is kinda sad that the api/v3/resolve_object endpoint was working without auth before the 0.18 release. Maybe I can see if we can get an api endpoint specifically for this? Without needing auth and without returning all the post information that we aren't interested in.

Ideally what I’d love is if posts worked like communities. For example you can navigate to https://lemmy.world/c/lemmy_support@lemmy.ml and you’ll be taken to the community page on Lemmy.world. But if we could link to something like https://lemmy.world/p/1543053@lemmy.ml and land on a particular post, that would make having to do a lookup completely pointless.
There is some good and some bad news for this. They are aware of this problem, and are having discussions to change it. But I don't know when it is coming. And I agree that a lookup would be useless if we can simply create the url directly.
Your redirect idea would probably work excellently as a browser extension — there are are redirect extensions like that for Mastodon already, actually.
As for the domain… the only thing I can think of would be, like you said, a Lemmy instance.
Firefox already has the Lemmy Link extension to do this. It seems to work pretty well from what I've seen.
Yeah a browser extension could be a good alternative. I was initially hoping to use a website based tool so that it could work regardless of the users platform / browser.
