API seems to be fine! I'm admittedly using AI for the integration, so minimal exposure on my end, but agents seem to be good at navigating the API which is good.
I'm using it for my project Leviath (leviath.dev), focused on building structured agents. In particular, the way that agents are constructed is via a graph, and so I have a TUI with this that allows both viewing runs, and creating agents with it now in a terminal nicely :D Previously only the web interface really was viable, now it's all doable via CLI which is nice for folks who just want to go through there.
