How to use YouTube API to check if a video is restricted?

问题

When embedding this YouTube video for example, we get This video contains content from... who has blocked it from display on the website error message.

How can I use the API to find if a video is blocked or not?

The nearest parameters I found are status and contentDetails:

GET https://www.googleapis.com/youtube/v3/videos?part=status&id=dYQ2IyMuPes&key={YOUR_API_KEY}

Which returns no indication about the restriction:

   "contentDetails": {
    "duration": "PT2M",
    "dimension": "2d",
    "definition": "hd",
    "caption": "false",
    "licensedContent": true,
    "projection": "rectangular"
   },
   "status": {
    "uploadStatus": "processed",
    "privacyStatus": "public",
    "license": "youtube",
    "embeddable": true,
    "publicStatsViewable": false
   }

回答1:

Check if it is restricted in the region contentDetails.regionRestriction or age-restricted content contentDetails.contentRating or content claimed by partner contentDetails.licensedContent? I am just speculating here too.

Edit: You can use this to check if it is embeddable too status.embeddable.

Be sure to have the "part" set correctly. It's a required field and you probably have "snippet there" and you need "contentDetails". (or "snippet,contentDetails" for both)

Example:

GET https://www.googleapis.com/youtube/v3/videos?part=contentDetails&id=OoKpYXTmYak&key={YOUR_API_KEY}


{
 "kind": "youtube#videoListResponse",
 "etag": "\"XpPGQXPnxQJhLgs6enD_n8JR4Qk/Xn7P-qyclepPOIFp9Bn69FdtR-4\"",
 "pageInfo": {
  "totalResults": 1,
  "resultsPerPage": 1
 },
 "items": [
  {

   "kind": "youtube#video",
   "etag": "\"XpPGQXPnxQJhLgs6enD_n8JR4Qk/_vu8XkjotVqxtJKQ2peTcRK8TYE\"",
   "id": "OoKpYXTmYak",
   "contentDetails": {
    "duration": "PT1M41S",
    "dimension": "2d",
    "definition": "hd",
    "caption": "false",
    "licensedContent": true,
    "regionRestriction": {
     "allowed": [
      "ES",
      "US"
     ]
    },
    "projection": "rectangular"
   }
  }
 ]
}

This is allowed in the US and Spain only
