After updating, validate that your script registers the Premium tier status. You can check your remaining daily and monthly allowances by querying the /users endpoint using a curl command:
if == " main ": # Step 1: Identify the old "prod" key by its label keys = list_keys() old_key_id = None for key in keys: if key["attributes"]["label"] == "automation-prod-v1": old_key_id = key["id"] break
import os import requests def get_file_report(file_hash): # Retrieve the premium key from environment variables api_key = os.environ.get("VT_PREMIUM_API_KEY") if not api_key: raise ValueError("Missing VT_PREMIUM_API_KEY environment variable.") url = f"https://virustotal.comfile_hash" headers = "accept": "application/json", "x-apikey": api_key response = requests.get(url, headers=headers) if response.status_code == 200: return response.json() else: print(f"Error: response.status_code") return None # Example usage with a known malicious hash hash_to_check = "44d88612fea8a8f36de82e1278abb02f" report = get_file_report(hash_to_check) Use code with caution. Public vs. Premium API: Architectural Comparison Public API Tier Premium API Tier (Updated v3) Strict (4 requests / min) High-throughput (Customizable SLA) Data Privacy Files uploaded are shared publicly Commercial privacy options available Advanced Search Not available Full search modifiers (e.g., size, type, downloads) YARA Support Full Livehunt and Retrohunt integration Relationships Basic metadata Full behavior graphs and execution chains Best Practices for Quota Management
Never hardcode your Premium API key inside your scripts. Use environment variables or a secure vault (like AWS Secrets Manager or HashiCorp Vault) to inject the key at runtime. 2. Querying a File Report (Python Example) virustotal premium api key upd
Below is a production‑ready example of how to handle a URL scan using the Premium API:

Understanding the functional boundaries between the free community access tier and a premium corporate deployment ensures your automated scripts do not halt due to request exhaustion. Public vs Premium API - VirusTotal documentation After updating, validate that your script registers the
Understanding the technical boundaries between the free public key and the premium infrastructure highlights why enterprises make the financial investment. Feature / Limit Public API Key Premium API Key Strict 4 requests per minute High-capacity (Customized per SLA) Daily Request Caps 500 requests per day Millions (Scales with enterprise tier) Commercial Use Strictly prohibited Fully allowed and encouraged Search Functionality Hash lookup only Complex metadata, string, and behavioral search YARA Hunting Not available Continuous live and retroactive hunting Contextual Metadata Basic antivirus detection names
Once you have the key, settings change. Here is how to manage an to your key.
: Execute thousands of queries per minute without rate-limiting bottlenecks. Querying a File Report (Python Example) Below is
: Access detailed behavioral execution information and PCAP files for deeper analysis.
Treat your threat intelligence keys like administrative passwords. Rotate them at least once a year, or immediately upon team member offboarding. 6. Conclusion
Unlike the free API, which you can copy instantly from your profile settings, a Premium API key requires a formal request process.

As of Q2 2025, VirusTotal has deprecated most v2 API endpoints. Any "update" to your scripts or SIEM integration must now use the v3 API.
