Heliophysics Events Knowledgebase API
Third party clients can communicate with the Heliophysics Events Knowledgebase (HER) via our web API. Usage of an API function amounts to using HTTP to fetch a web document. The base url for all API calls is (including the question mark)
http://www.lmsal.com/her/dev/search-hpkb/hek?
Following the url base, one can append a list of keywords to specify the type of command and options for that specific command.
Search for Features/Events in HER
To search for Features and Events in HER, one must append to the base url:
cmd=search
In addition to the command (cmd), one must specify which event type to search for. For all event types, use **
cmd=search&event_type=**
For some but not all event types, use a comma delimited list of two-letter abbreviations. E.g. the following specifies that one wishes to search for active regions, flares and emerging flux regions (see http://www.lmsal.com/helio-informatics/hpkb/VOEvent_Spec.html for full list of event types).
cmd=search&event_type=ar,fl,ef
