How to access information about user, browser and OS through API

Hi, I’m looking through the event object I get from calling ‘List a Project’s Events’. And I can’t find what browser was used when this event occurred nor what user and which OS. I can see this information on the events page for the event on sentry.io when I’m logged in, so I assumed it was accessable through the API as well, could someone please help?

You should be able to find this information under tags, the format would like similar to:

"tags": [
      {
        "value": "Chrome 28.0",
        "key": "browser"
      },
      {
        "value": "Other",
        "key": "device"
      },
      {
        "value": "error",
        "key": "level"
      },
      {
        "value": "Windows 8",
        "key": "os"
      },
      {
        "value": "3a18797e31ed1de128a029219f521e0f90da26d6",
        "key": "release"
      },
      {
        "value": "http://example.com/foo",
        "key": "url"
      },
      {
        "value": "id:1",
        "key": "user"
      }
    ],
