Hi everyone, I have some technical questions regarding federation. Answers backed by documentation would be perfect.
- Is there a way to get the list of federated instances of a specific instance?
- (Regarding question 1, should this consider active followers between instances? If not actively defederated/blocked, when one account follows another from another instance, the two instances get federated, right?)
- Can I get a list of actively blocked/defederated/muted instances?
- How does this change between applications? Are for example Lemmy and Mastodon the same?
My goal is to possibly create a graph/network analysis.
Thank you for your help.
You can see the list of federated instances of each instance at https://example.com/instances
You can also get that data in json format by using https://example.com/api/v3/federated_instances
https://lemmy.readme.io/reference/getfederatedinstances
Mastodon and Lemmy are both using the ActivityPub protocol (Lemmy uses some extensions to federate downvotes and some other actions) to communicate between instances, but the API to interrogate the instance will be different.
This is exactly what I am looking for. I am interested also in how other federated applications do it. I had a look at Pixelfed’s documentation, but they don’t seem to have an API for that… Do you know anything about other services?
