FEP-844e: Capability discovery has been published to the FEP repository:
https://codeberg.org/fediverse/fep/src/branch/main/fep/844e/fep-844e.md
I already use it to signal RFC-9421 support. An anonymous Application
object is added to actors:
{
"generator": {
"type": "Application",
"implements": [
{
"name": "RFC-9421: HTTP Message Signatures",
"href": "https://datatracker.ietf.org/doc/html/rfc9421"
}
]
}
}
All important information is embedded, so additional HTTP requests are not necessary.
