Probably you have to write you own script to do this.

something like this https://github.com/zaach/jsonlint

You probably could use textproc/jq for this with the --exit-status argument. See https://stedolan.github.io/jq/manual/#Invokingjq

$ echo '{valid: true}' | jq -e; echo $?
parse error: Invalid numeric literal at line 1, column 7
4
$ echo '{"valid": true}' | jq -e; echo $?
{
  "valid": true
}
0

devel/yajl comes with json_verify which can be used for syntax checking JSON files.

However if you want to get fancy and also verify that the file conforms to a given schema, devel/py-jsonschema (or any other validation tool from http://json-schema.org/implementations.html) is worth a look.
