When querying /v2/images , you can look at the public attribute:

  "images": [
    {
      "id": 7555620,
      "name": "Nifty New Snapshot",
      "distribution": "Ubuntu",
      "slug": null,
      "public": false,
      "regions": [
        "nyc2",
        "nyc2"
      ],
      "created_at": "2014-11-04T22:23:02Z",
      "min_disk_size": 20
    }

Your snapshots, as opposed to base distros and One-Click apps, will be "public": false For example using something like the jq utility, you can filter out public images:

curl -X GET -H 'Content-Type: application/json' \
-H 'Authorization: Bearer $TOKEN' \
https://api.digitalocean.com/v2/images?per_page=200 \
| jq '.images[] | select(.public == 'false')'

Though it might make sense to add additional filters directly into the API as we already do with ‘distro’ and 'application’ We collect API feedback in GitHub issues:
