To know what software an instance is running (Mastodon, Pleroma, Akkoma, Firefish, Friendica, etc), have to make 2 calls:
1. `/.well-known/nodeinfo` - get the `href` for a nodeinfo link e.g. https://mastodon.social/.well-known/nodeinfo
2. `/nodeinfo/2.0` (possibly 1.0 or 2.1 too) - get the `software.name` e.g. https://mastodon.social/nodeinfo/2.0
Andβ¦ both are not CORS-enabled (again) for web apps to request π π’
