Kind of hard to rationalise, but sometimes when a json body is of a slightly unintuitive format (in this case, it's not simply a collection like one might assume, but a one element hash with what we're interested in being the value) I like to explicitly assign the important value just to make that a bit more obvious.

Not a big deal though so happy to condense it down if I'm alone in having been tripped up by the assumption that api calls for collections will naturally just be returned as an array.
