New thumbnail endpoints can be found on thumbnails.roblox.com. We do not recommend relying on endpoints from www.roblox.com because they are gradually being replaced.

See Official List of Deprecated Web Endpoints for announcements about other endpoints that we plan to remove.

Is there any endpoint with the same behaviour as https://www.roblox.com/asset-thumbnail/image?assetId=id&width=420&height=420&format=png? I don’t want to use the API directly because it would require an extra request to get a thumbnail.
