List of Federated Instances (feddit.it)

Hi everyone, I have some technical questions regarding federation. Answers backed by documentation would be perfect.

  1. Is there a way to get the list of federated instances of a specific instance?
  2. (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?)
  3. Can I get a list of actively blocked/defederated/muted instances?
  4. 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 a Mastodon, Lemmy, PixelFed or kbin 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?
