YouTube video details now include AI disclosure

The /v1/youtube/video endpoint now includes YouTube’s ‘How this content was made’ disclosure. The new ai_label field provides details such as label (e.g., ‘Made with AI’ or ‘Auto-dubbed’), text, is_altered_or_synthetic, and is_auto_dubbed flags. This helps you identify content that creators have declared as altered or synthetic, or that YouTube has machine-translated.
