Ephemeris source, reliability, and cost

[heymartinadams]

In the ReadMe is says: “Chart data is loaded from a remote online ephemeris REST service.” Where does the ephemeris originate from (source)? This is more a question of curiosity.

A related and more significant question since I’m looking into using this as a module in an app, is: Is this service guaranteed to be offered in the future (reliability), and if so, for free (cost)? I would be unable to use this module if there’ll be a significant cost associated to it or if at some point the service is terminated.

Thank you!

Answer to source: morphemeris, which uses swisseph.
