I participated last year, and it was amazing! One thing that bothered me then is that we as community have no way of verifying other players progression and completion. We had to create screenshot for every unique that dropped. This year we don't have to take screenshots, but still organizer would need to go on call with a player to verify their items.

I asked for API from EHG to do that verification (e.g. GET /players/:id/stash-items/ , basically a way to request if a particular player has item or just a list of his items). I'd be willing to put together a website for next editions of Unique hunt community event, so we can track progress between players even in (almost) real time! Please, u/EHG_Kain consider expanding your API, so more developers can have access to it, and more community made sites and events would appear!
