Sematext Cloud API


Sematext Cloud exposes REST API to access its functionalities. The REST API can be used to easily manage your Account and Apps remotely, without the need to be logged-in via a browser. It also makes it possible to automate certain tasks, such as creation of new Apps, definition of Alert Rules, etc.

To use the API, you need the API key of your account - it can be found here for US region or here for EU region. You can also get the API Key using Login endpoint by providing username/password. The API Key needs to be passed as Header parameter with name Authorization and value should be in the format apiKey <Value>. e.g. apiKey e5f18450-205a-48eb-8589-7d49edaea813

Access to API key of some account is allowed for OWNER, BILLING_ADMIN and ADMIN users. Users with USER role cannot access API key of that account, though they can always use their own account's API key to manage their own Account, Apps, etc.

Request/Response format

All API calls accept JSON in requests and return JSON response. For POST requests not all attributes listed in API Explorer are mandatory. All API responses contain attribute success which has value true or false. Optional response attributes are message (which provides textual message about what API call did) and data, which contains data returned by the call, under specific response key (apps in the below example). Example of response:

  "success": true,
  "message": "Created application new-solr-app, token is: xxxxx-xxxx-xxxxx",
  "data": {
    "apps": [
        "id": 20651,
        "name": "new-solr-app",
        "appType": "Solr",
        "appTypeId": 1,

Also, all responses contain an HTTP code which describes success or failure. In case of a successful call, HTTP code will be 200 (OK). Any other non-2XX HTTP code represents an error (most commonly used codes are 400 - Bad Request, 401 - Unauthorized, 403 - Forbidden and 500 - Internal Server Error).
