Does #Mastodon implement #ActivityPub client-server API?
I do what https://www.w3.org/TR/activitypub/#client-to-server-interactions tells me to:
- I look up my own Actor object and look up its outbox (qoto.org/users/robryk/outbox in my case),
- I send a POST with appropriate 'Authorization: Bearer ...' header,
and then I get 404 (GETs on that URL do succeed and show a collection).
Is client-server activitypub something that is ~ever implemented?
