The Heliophysics Data Application Programmer's Interface (HAPI) specification is a time series download and streaming format specification. When data are available from a HAPI server, there is no need to download data files and write custom file reader programs. Using a HAPI client library, data can be loaded into an array using a single command in IDL, Javascript, MATLAB, and Python.

• Use this interface to
  • generate a HAPI URL to download data,
  • plot data from a HAPI server, and
  • generate cURL / IDL / IDL SPEDAS / Javascript / MATLAB / Python / Python SPEDAS / Wget scripts that read and plot the selected parameter.
• Begin by selecting a HAPI data server on the left or selecting an example below.

• Plot SYM-H timeseries from CDAWeb HAPI server
• Plot empire_tsi timeseries from LASP/LiSIRD HAPI server
• Plot B from T96 model at Cluster 2 location from AMDA HAPI server
• Plot HPlus_BEST_T1 energy spectra in CHEMS_PHA_BOX_FLUXES_FULL_TIME_RES dataset from DataShop
• List SYM-H timeseries from CDAWeb HAPI server
• Create Python script to read SYM-H timeseries from CDAWeb HAPI server
• Create MATLAB script to read SYM-H timeseries from CDAWeb HAPI server
• Create IDL script to read SYM-H timeseries from CDAWeb HAPI server
• Use this interface to test a server not in server list drop-down menu.
