FAIRsharing record for: Heliophysics API

This FAIRsharing record describes: The Heliophysics Data Application Programmer’s Interface (HAPI) specification is a time series download and streaming format specification. A more detailed overview is given in Weigel et al. (2021). The HAPI specification was recommended by COSPAR in 2018 as the common data access API for space science and space weather data.

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 using HAPI IDL, Javascript, Java, MATLAB, and Python clients. Data from HAPI servers is also accessible to users of Autoplot, PySPEDAS, and IDL SPEDAS. Sample scripts and containing instructions for accessing data using the above–listed clients may be found by selecting a server, dataset, and time range at the web interface http://hapi-server.org/servers/.

A list of HAPI-compliant data servers is available at http://hapi-server.org/servers/.

The hapi-server GitHub project (https://github.com/hapi-server) contains a collection of repositories for HAPI–related software and documentation, including client and server libraries and code for verifying and testing a HAPI server.
