Error handling

Each API response contains a success (boolean) field. When success is false, the error (string) field with the error description is also included.

Example success response:

{
	"success": true
}

{
	"success": false,
	"error": "Missing data"
}

In addition, various HTTP errors may occur, e.g. 404 if the endpoint does not exist or 500 if API is unavailable due to some backend malfunction. If the status is not 200, the contents of response body is unpredictable and should be ignored.
