"As of now, YouTube Kids does not offer a dedicated public API that exclusively returns YouTube Kids content. The standard YouTube Data API v3 can be used to search and list YouTube videos, but it doesn’t include a filter specifically for YouTube Kids content. This means there’s no guaranteed way to restrict results to only those available in the YouTube Kids app using the public API. If you're developing something intended for child-friendly content, you would need to implement your own filtering logic—perhaps by curating channels manually or using metadata like content ratings, titles, or tags (though these are not always reliable). Hopefully Google/YouTube provides more support for this in the future!"
