Heliophysics Application Programmer's Interface (HAPI)

The Heliophysics Application Programmer's Interface (HAPI) is a set of specifications for services to enable access to data and metadata.

HAPI Data Specification

The Heliophysics Application Programmer's Interface (HAPI) specification for a standard set of services for delivering digital Heliophysics time series data.

HAPI constitutes a minimum but complete set of capabilities needed for a server to allow access to the time series data values within one or more data collections. Because of this focus on access to data content, HAPI is very light on metadata and data discovery. Within the metadata offered by HAPI are optional ways to indicate where further descriptive details for any dataset could be found.

See specification for details.
