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.

| popularity This indicator reflects the "current" impact/attention (the "hype") of an article in the research community at large, based on the underlying citation network. | Average | |
| influence This indicator reflects the overall/total impact of an article in the research community at large, based on the underlying citation network (diachronically). | Average | |
