Does anyone know how to use Google Flight RPC or how to post a json array to it? The only documentation I've found for it is here. It shows the responses and part of the requests. I'm not sure how to build and post a json array using the following example from part 1 of the linked documentation.

[,[[,"fs","[,[,[\"SJC\"]\n,\"2012-04-05\",[\"EWR\",\"JFK\",\"LGA\"]\n,\"2012-04-12\"]\n]\n"]
]
,[,[[,"b_ca","54"]
,[,"f_ut","search;f=SJC;t=EWR,JFK,LGA;d=2012-04-05;r=2012-04-12"]
,[,"b_lr","11:36"]
,[,"b_lr","1:1528"]
,[,"b_lr","2:1827"]
,[,"b_qu","3"]
,[,"b_qc","1"]
]
]
]
Also, how do I set up the necessary headers using cURL?
