hapi
HAPI, the
Heliophysics Data Application Programmer’s Interface
is a protocol for serving streamed time series data.
This reader can read HAPI CSV and binary tables
if they include header information
(the include=header request parameter
must be present).
An example HAPI URL is
https://vires.services/hapi/data?dataset=GRACE_A_MAG&start=2009-01-01&stop=2009-01-02&include=header
While HAPI data is normally accessed directly from the service, it is possible to download a HAPI stream to a local file and use this handler to read it from disk.
This format cannot be automatically identified
by its content, so in general it is necessary
to specify that a table is in
HAPI
format when reading it.
However, if the input file has
the extension ".hapi" (case insensitive)
an attempt will be made to read it using this format.
