Summary
The Smartcitizen V0 API is a publicly available interface allowing anyone to develop applications and experiments on top of the Smartcitizen platform. For more general and hardware information check the documentation.
# Shell example
# In the shell examples we use either curl or the `http` (HTTPIe) program
// Javascript example
# The json responses will look something like this:
[
{
"example_response":"example_value"
}
]
Schema
All API access is over HTTPS (with the exception of /add) and accessed via api.smartcitizen.me
Blank fields are included as null instead of being omitted.
All timestamps are returned in ISO 8601 format:
YYYY-MM-DDTHH:MM:SSZ
Root Endpoint
You can issue a GET request to the root endpoint to get all the endpoint categories that the API supports:
$ curl https://api.smartcitizen.me
http GET https://api.smartcitizen.me/v0/
// Run this in your browser console
fetch('https://api.smartcitizen.me/v0/')
.then(function(response) {
return response.json();
})
.then(function(myJson) {
console.log(JSON.stringify(myJson));
});
HTTP/1.1 200 OK
{
"current_user_url": "https://api.smartcitizen.me/v0/me",
"components_url": "https://api.smartcitizen.me/v0/components",
"devices_url": "https://api.smartcitizen.me/v0/devices",

"sensors_url": "https://api.smartcitizen.me/v0/sensors",
"users_url": "https://api.smartcitizen.me/v0/users"
}
JSON-P Callbacks
You can send a ?callback parameter to any GET call to have the results wrapped in a JSON function.
Postman
We recommend that you try our API using Postman, we have created a shared collection that you can import from here https://www.getpostman.com/collections/85a92402907e3cb07759
Versioning
By default, all requests receive the v0 version of the API. We encourage you to explicitly request this version via the URL or the HTTP Accept header.
| endpoint | |
|---|---|
| BAD | https://api.smartcitizen.me/users |
| GOOD | https://api.smartcitizen.me/v0/users |
Accept: application/vnd.smartcitizen; version=0,application/json
Authentication
There are 3 ways you can access the API. OAuth 2.0 is the recommended method.
OAuth 2.0
# Send authenticated POST for username 'user1', which should return the 'access_token'
$ curl -XPOST https://api.smartcitizen.me/v0/sessions -d "username=user1" -d "password=password"
# OAuth2 Token (sent as a parameter)
$ curl -G https://api.smartcitizen.me/v0/me?access_token=OAUTH-TOKEN
# OAuth2 Token (sent in a header)
$ curl -H "Authorization: Bearer OAUTH-TOKEN" https://api.smartcitizen.me/v0/me
You can obtain a general access_key by sending an authenticated POST request to https://api.smartcitizen.me/v0/sessions
A basic example resides here https://example.smartcitizen.me and its source code is here https://github.com/johnrees/smartcitizen-oauth-example.
Applications can be added here https://id.smartcitizen.me/oauth/applications. Whilst in development this is completely open for public access but this will change. The correct Client ID and Client Secret can be found at https://id.smartcitizen.me/oauth/applications.
HTTP Basic Auth
# Add a base64 encoded hash of 'username:password' in the header
curl 'https://api.smartcitizen.me/v0/me' -H 'Authorization: Basic am9objpzbWFydHBhc3M='
# NOT RECOMMENDED - add username and password in the header
curl 'https://api.smartcitizen.me/v0/me' --user username:password
This method enables you to authenticate your requests with your username and password. Despite using SSL we do not recommend this method as it can be very easy to accidentally share your secret credentials.
Filtering Responses
Pagination
$ curl --include 'https://api.smartcitizen.me/v0/users?page=5'
HTTP/1.1 200 OK
Link: <https://api.smartcitizen.me/v0/users?page=1>; rel="first",
<https://api.smartcitizen.me/v0/users?page=173>; rel="last",
<https://api.smartcitizen.me/v0/users?page=6>; rel="next",
<https://api.smartcitizen.me/v0/users?page=4>; rel="prev"
Total: 4321
Per-Page: 25
Most endpoints that return more than a single result e.g. /v0/users, v0/devices will return blocks of the result set that can be manipulated using the following parameters.
| Parameter | Default | Description |
|---|---|---|
| page integer |
1 | page |
| per_page integer |
25 | page |
The headers will include links to the Total results count, number of results shown Per-Page and first, last, next and previous results.
Global Search
curl -XGET https://api.smartcitizen.me/v0/search?q=barcelona
HTTP/1.1 200 OK
[
{
"id": 506,
"type": "Device",
"name": "Barceloneta Sensor",
"description": "Barcelona sensor place at a 7th floor in front of the beach. Working on different batteries to have more autonomy outdoors. Next: Solar Panel!",
"owner_id": 3,
"owner_username": "tomasdiez",
"city": "Barcelona",
"country_code": "ES"
}
...
To search both Users and Devices at the same time you can use the global search endpoint.

Basic Searching
Similar to the pagination, you can filter and sort most responses that return more than one result. This is done with the Ransack library. You can query different endpoints and filter them by using search matchers.

|---|---|---|---|
| /users?q[username_eq]=adam | string | adam | Users where username equals 'adam' |
| /users?q[username_cont]=osc | string | osc | Users where username contains 'osc' |
| /devices?q[name_cont]=sck | string | sck | Devices where username contains 'sck' |
| /devices?q[owner_id_eq]=1 | integer | 1 | Devices where owner ID equals 1 |
| /devices?q[tags_name_in]=Barcelona | string | Barcelona | Devices which have the tag 'Barcelona' (case sensitive). |
| /devices?with_tags=Barcelona|Amsterdam | string | Barcelona|Amsterdam | Devices which have ANY of the tags separated by PIPE | |
| /devices?q[postprocessing_id_not_null]=1 | integer | 1 | Devices where postprocessing is not_null |
| /sensors?q[id_lt]=100 | integer | 100 | Sensors where ID less than 100 |

http DELETE https://api.smartcitizen.me/v0/devices/10
HTTP/1.1 200 OK
You can only delete devices that you own. After a device is deleted with the API there will be a grace period in which you can contact support to reinstate a device if you have removed it in error. After this grace period has passed, the device and its data will be removed permanently from our databases and cannot be restored.
Sensors
Every device has sensor(s). A sensor is something on a device that can record data. This could be anything, some examples are - temperature, humidity, battery percentage, # wifi networks.

Post Readings
A device has one Blueprint we call kit, and a blueprint has many sensors through components.
Most devices on the platform share the same blueprint, a default SCK 1.1 (e.g. Kickstarter Board). But new devices (e.g. Raspberry Pi's, new Sensor Add-ons) might use a different Blueprints.

Adding/editing a device's tags
PATCH https://api.smartcitizen.me/v0/devices/:id
Include comma seperated list of tag names in user_tags property.
For example, if there are tags with the names interesting and cool-hardware you could add these tags to a device by PATCHING user_tags = 'interesting,cool-hardware'.
If you then wanted to remove cool-hardware you would PATCH again, but without the second tag i.e. user_tags = interesting.

Real Time
Websockets
The real time API uses websockets to push devices information in real-time and it is based on the famous socket.io library. We support WSS, WebSockets over SSL/TLS, like HTTPS. We also support fallback to long polling for older browsers.
data-received is currently the only available topic. Everytime a device publishes data to the platform data is pushed over the channel. With the same model as device GET.
