API Documentation
There're two kinds of tokens: user token and node token.
The /node/* API calls need node token specified.
- with query string: xxxx/xxxx?access_token=[your token here]
- with "Authorization" header: Authorization: token [your token here]
Arguments in post body must be specified in application/x-www-form-urlencoded format: arg1=xxx&arg2=xxx, application/json and multipart/form-data are not accepted.

Access through Data Exchange Server
".well-known" API prints all the available resources on that node. This API needs the node online.
curl -H "Authorization: token d6d68b4b6b43f213569f5832dd8277b2" https://iot.seeed.cc/v1/node/.well-known
response:
{"status": 200, "msg": [

"GET /v1/node/Grove_Example1/with_arg/int_arg -> float cx, float cy, float cz, int degree",
"POST /v1/node/Grove_Example1/float_value <- float f",
"HasEvent Grove_Button1 button_pressed",
"POST /v1/node/Grove_Gyro_ITG3200/zerocalibrate <- void"]}The items on the right of the right arrow "->" are the properties that you can read via that API call, while the items on the right of the left arrow "<-" are the values that you can write to that method/action.
"HasEvent" keyword indicates that there's a particular event which will be reported by that grove module, you can receive an explicit semantic event message from the event reporting websocket, e.g. {u'msg': {u'button_pressed': u'0'}} which means the button attached to GPIO0 is pressed.
Access through Data Exchange Server

Put the node into deep sleep mode in which the whole board's power will be shut down except that power of CP2102 if the system is powered by USB.
This will reduce the current consumption of the board to ~10mA if it's powered by micro USB (due to the usb to serial chip CP2102). And the current will drop to ~1mA if the board is powered by battery.
The sleep will not be intermittently triggered. You need to call the sleep API every time you want the node to sleep. You can continue to send GET/POST requests after a sleep command has been executed, the node will return a 404 status code and a message saying it's offline. Then the node wake up and join the router within about 5 seconds. You do some stuff and put the node into sleep again.

Change the data exchange server for a specific node. As the changing will be taken place at the node side, this API needs the node online. This API will cause the node reboot once. After rebooted, the node will interact with the configured data exchange server for data and event transmission. And the configured data exchange server can be queried with the nodes/list API.
curl -X POST https://iot.seeed.cc/v1/node/setting/dataxserver/192.168.31.2?access_token=d6d68b4b6b43f213569f5832dd8277b2
If you want to get the node event at any time, you should open a websocket in the client's background. After, send the Node Key to complete the handshake. Like this:
<script>
var ws = new WebSocket('wss://iot.seeed.cc/v1/node/event');
ws.onopen = function() {
ws.send("d6d68b4b6b43f213569f5832dd8277b2");
};
ws.onmessage = function (evt) {
alert(evt.data);
};
</script>Then, the onmessage will get event data when node post it.
The event data format like this:
{'event_name_here': 'event_data_here'}
