I use VirusTotal’s sandboxing tools/reports and graphs for this kind of thing, and their free API limits are suitable for many needs, although there are limits to individual upload size in the tens of MB on the web, which are somewhat higher if using CLI iirc, but not by much. I think their paid offerings may raise these upload size limits.
