Overview of the NASA CDAWeb data browsing, SSCweb orbit, and Heliophysics Data Portal heliophysics web service APIs

The Space Physics Data Facility (SPDF) https://spdf.gsfc.nasa.gov/ manages the non-solar archive and associated services, and provides machine-readable APIs for the popular CDAWeb data browsing system https://cdaweb.gsfc.nasa.gov/WebServices/ , SSCweb orbit location query system https://sscweb.gsfc.nasa.gov/WebServices/ , and recently added an API for the Heliophysics Data Portal https://heliophysicsdata.gsfc.nasa.gov/WebServices/ to search for heliophysics resources, described by SPASE metadata. We'll present an overview of these APIs and software packages for calling them.
