This code: https://codeberg.org/rimu/pyfedi/src/branch/main/app/api/alpha

Its mostly freamon and rimu working on that part. Iirc its meant to be lemmy api compatible, but i think there are some adaptations needed to accomadate the piefed way differences.

Freamon got a fork of a lemmy app to sort-of work back in september (https://matrix.to/#/!NVUzKiFppMtECaxHQm:matrix.org/$KJqJfus8DVy-B64AC8uWEQ9oiGsRA04AReRF-05nQYA?via=matrix.org&via=tchncs.de&via=jeena.net) so the alpha api stuff has been coming in since then.
