Hi there!
I needed a Micropub Endpoint for my Kirby site, but since there was no plugin, I wrote one myself. And now it’s mentioned on Kirby Kosmos Ep 6. Oh help.
Anyway, if you are interested, use it. And if you get into troubles, please shout here or file an issue on Github.
The plugin is here.
More information on Micropub is here.
An example of a Micropub client is here or here.
