Virustotal Premium Api Key Upd May 2026
Cause: You are accidentally using the public API endpoint (/api/v3/) without the Premium key header, or the new key was mis-classified as a "Basic" key due to a billing sync delay.
Fix: Verify your subscription via /api/v3/users/me and check the premium boolean. If false, contact VirusTotal support to re-sync your license.
