[QUOTE]VT APIv3 is the preferred way to programmatically interact with VirusTotal. While older API endpoints are still available and will not be deprecated, we encourage you to migrate your workloads to this new version. It exposes far richer data in terms of: IoC relationships, sandbox dynamic analysis information, static information for files, YARA workloads management, crowdsourced detection details, etc.[/QUOTE]
