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.

Space Weather-related data are available through this interface and HAPI software from AMDA , CAA , CCMC , CDAWeb, DAS2, INTERMAGNET, KNMI, LISIRD, SSCWeb, and ViRES.

HAPI servers are available from this interface.

• Use this interface to
  • generate a HAPI URL to download data,
  • plot data from a HAPI server, and
  • generate scripts (with install instructions) that read and plot the selected parameter using HAPI clients for cURL / IDL / IDL SPEDAS / Javascript / MATLAB / Python / Python SPEDAS / Python Kamodo / Wget. Example scripts can be created using links in "Example Queries".
• Begin by selecting a HAPI-enabled data server on the left or selecting an example query below.
