They had API access designed at one time when Starfinder ran it. I was able to get most of the limited API working with an android app with his help, but that support died with him leaving a few years ago, and I never got a response from them since.
I came up with my own solution to the problem and built a chatlog parse program (which is all EL really is) that sends data to my twitch chatbot to display skills and globals live on twitch. Still in progress but as I polish it up I might be able to publish it. Skills and globals and skill analysis scripts are done, probably do some hunting trackers next for live DPS.
But as far as EL and their data, ever since it was sold, Its pretty clear they don't want to share the access anymore.
