Response is created in:

iotagent-json/lib/bindings/HTTPBinding.js

Line 475 in eccfc52

res.status(200).send(JSON.stringify(list.commands.map(parseCommand).reduce(concatCommand, {})));

command returned as stringified, so is text/html content-type

The same implementation is found in UL iotagent also
