@cookie_mumbles I had a quick test with my alts to see where justmytoots works, as several fedi implementations support various degrees of the Mastodon API.
No accounts/lookup endpoint:
- GNU Social
- Akkoma
- Misskey
Works with JMT:
- Pleroma[0]
*Almost* works with JMT:
- IceShrimp
Mastodon supports both acct=@user@host and acct=user@host, but IceShrimp only supports it without the leading @ and JMT always sends the leading @.
[0] Unexpected! I wonder if it was added after the Akkoma fork or if Akkoma removed it.
