Kerbal Data Output is a data export program for Kerbal Space Progra It's currently in it's early stages, so please bear with me for any bugs and such.
This is the data it exports, in no particular order.
This exports information on all the vessels in the simulation.
Information on the active vessel.
Information on the given vessel ID. You can get this ID from either of the two above vessels data export paths, in the JSON output of the "id" field.
Data on all the celestrial bodies in the simulation.
Data on the given celestrial body.
Information on the simulation, such as the game's warp rate and paused/unpaused state.
Returns the KSP version.
How to get the data
As of now, there's no pretty graphs or anything, as I've been focusing on the JSON api itself. To get data out you just need to go to http://localhost:8080<path> -- where <path> is the given data export above.
