In december 2018, JPL/NAIF announced an experimental API RESTful interface for their new WebGeoCalc server (which make online SPICE calculations). Documentation and JavaScript examples are already available.

This package provides a Python interface to make SPICE calculations through this API.


WebGeoCalc is not design to handle heavy calculation. If you need to make intensive queries, use Spiceypy or SpiceMiner package with locally hosted kernels.
