How to request actors json

Hi! I am trying to explore ActivePub specification, and It would be good if I can check examples online, with browser or curl. I've registered on fediverse.blog, but I did not find any place where to start. For example I am https://fediverse.blog/@/nataraj How should I get actors json about myself?

you can request this url with the Accept: application/activity+json header, it should send you the json  you can also normally access user's outboxes on /@/USER/outbox (but there are only published articles inside for the moment, nothing else)  If I may add, when debugging Plume's AP stack, I always use curl, just add -H "Accept: application/activity+json" to your commands and it works, it's easier than using Firefox network debugging tools
