Thumbnail APIs

Asset Thumbnails

• https://assetgame.roblox.com/Thumbs/Asset.asmx/RequestThumbnail_v2?assetId=1818&assetVersionId=0&width=420&height=420&imageFormat=Png&thumbnailFormatId=0&overrideModeration=false

  • Returns {"d":{"final":true,"url":"https://tr.rbxcdn.com/139602eb7c640c43833470e07caada4a/420/420/Image/Png"}}

• https://www.roblox.com/item-thumbnails?params=[{assetId:1818}]

  [{
    id: 1818,
    name: "Crossroads",
    url: "/Crossroads-place?id=1818",
    thumbnailFinal: true,
    thumbnailUrl: "https://t7.rbxcdn.com/134692bb990302f51fb8f52cfcdd8083",
    bcOverlayUrl: null,
    limitedOverlayUrl: null,
    deadlineOverlayUrl: null,
    limitedAltText: null,
    newOverlayUrl: null,
    imageSize: "large",
    saleOverlayUrl: null,
    iosOverlayUrl: null,
    transparentBackground: false
  }]

  You can specify the small image size (110x110) with params=[{assetId:1818,imageSize:small}]. Otherwise it will default to large (420x420)

  Both of these APIs support JSONP, so this code can be embedded in any web page:

  $.getJSON('https://www.roblox.com/item-thumbnails?params=[{assetId:1818}]&jsoncallback=?', function(json) {
      alert(json[0].name);
  });
