You can generate an appropriate set of commands by opening the Chrome Developer console (View ... Developer ... JavaScript Console), (re)loading a page of interest, selecting the network tab, selecting a downloaded object, right clicking and then choosing (Copy ... Copy all as cURL). You should make sure that you only have one neuron displayed if you do not want to have to parse the object identifier relationships.
