hi @aaronedam, thanks for your question, - default api response is json format, this format is easy to parse then xml (eg directly usage in js/nodejs app..) - server cost is not too hight , api response is only static json data (data are sync. on midnight), so price is only for bandwige - i plan added crypto and comodities (like gold,silver etc)
