Hi,
that doesn't look valid GeoJSON to me, you have no other options than
transforming the JSON to valid GeoJSON (or to any other format recognized
by QGIS ogr provider), or you can create a vector layer from scratches and
and add the individual features in a loop, it largely depends on what you
need to do next with those data.
Both approaches require a bit of programming.
