Why can't we have a unified API across the fediverse to use in mobile apps?
Is there a reason why all the services, that use the ActivityPub protocol don't have a unified API?
None of the mastodon apps allow me to log in with a lemmy/kbin account.
Also none of the lemmy apps allow me to log in with a kbin account.
Even though kbin has both mastodon (microblogging) and lemmy (threads, communities) functionality.
Also, Pixelfed recently introduced "login with Mastodon", but all it really does is just create a new user on it's instance and copy over the mastodon followers and profile info.
Why can't we just have one account to rule them all?
OP is just asking why they a third party mastodon app can't login to a Lemmy or kbin server, which is a valid question.
From an authentication standpoint there's no reason for their auth flows to be at all different or use different endpoints relative to their domain.
The returned profile or account object might have different fields which could cause an app to crash, but there's no reason for every fediverse app to not use some of the same basic schemas and endpoints.
I'm not an expert, those who know more, please correct me.
Regarding logging-in with one account into another instance, I think that's not how it's intended to work. But I'm oot sure I understand what you're asking.
There is a lot of work to do, even outside of ActivityPub. As Dave mentions, we also need a common posting API. The most popular Mastodon client apps do not support either ActivityPub or Micropub. But a lot of progress can be made focusing on interoperability for the server-to-server part of the API. That should be the top priority with Threads set to join the fediverse.
If it does, I should be able to post images on the pixelfed app that show my username as @adonis.
It cannot work as stated because there could be another @adonis accounts in other instances and the only way to prevent that would be to centralize all the signups which goes against the whole idea of decentralization. That's why the user must be @adonis1@kbin.whatever as it is shown now.
Regarding the OAuth/JWT, again... not an expert, but what I understand is that that kind of integration is much stronger than the current system. AFAIK, it could work as you say, but that would make things much more complex for the servers; you usually provide OAuth authentication for a few services, I don't know how well that scales with ... hundreds / thousands (?) of authentication provders. But, who knows, maybe in the future it's implemented in one way or another.
We should take into account that this technology is fairly new and people are still building on it.

> With extensive work, these tools can all be made to work together under a single username. Every tool needs to be made aware of every other tool, and a lot of the actual federation code needs to be externalised to an all-encompassing server. This can be done without breaking any spec and without becoming incompatible with the rest of the Fediverse, but it’ll require a LOT of work.
You basically summarized my original plan for communick. The basic idea is:
Take the existing services, provide commercial hosting
Use the revenue to fund development of protocol-level integrations, contribute back to open source
Build tools to make it easy for companies to migrate away from Facebook/Twitter/Instagram/WhatsApp and own back their internet presence again
???
Profit / Destroy Big Tech.
Unfortunately, the amount of people willing to pay for commercial providers of social media is embarrassingly small, so I am stuck at step 1 and the best I could do is to build a SSO system for Matrix/Mastodon/XMPP, to let people use the same credentials on all "communick.com" servers.
ActivityPub has a C2S (client to server) API in addition to the S2S (server to server) API, it's just that nobody cared about it to implement it. And because nobody implemented it nobody iterated upon it so now it sits as this underspecified (and unusable) state.
Yea, but that's just a lowest common denominator (e.g. it doesn't include things like lemmy community sidebars), and also generally not appropriate for a client application. ActivityPub transmitts all events that are happening (posts, likes ...) between servers, and they are supposed to index and aggregate things (e.g. sum up votes, sort posts). It's just not feasible to expect the same from a mobile app for example, you'd have to at least create another standard for that.
So services end up implementing their own client APIs to fit their needs. And imo that's actually a good thing, because it allows them to try out features and specialize on different use cases. But afaik the ActivityPub people are working on another standard for client APIs, at least it's on their radar.
