Detect VPN, Proxy & Tor in Python

No dedicated call needed — the flags ride along with a normal lookup.

import os
from ipapi_io import IpApiClient

client = IpApiClient(api_key=os.environ["IP_API_IO_KEY"])

info = client.lookup("185.220.101.1")
f = info["suspicious_factors"]

print(f["is_vpn"])         # VPN service
print(f["is_proxy"])       # open / anonymizing proxy
print(f["is_tor_node"])    # Tor node
print(f["is_datacenter"])  # hosting / datacenter IP (often a bot)
print(f["is_spam"])        # known spam source
print(f["is_crawler"])     # known crawler / bot
print(f["is_threat"])      # listed on a threat feed

if f["is_vpn"] or f["is_proxy"] or f["is_tor_node"]:
    pass  # require step-up verification (CAPTCHA, 2FA)

A dedicated check against the live Tor node list, with a count of matching nodes.

tor = client.tor_check("185.220.101.1")

print(tor["is_tor"])          # True
print(tor["tor_node_count"])  # number of matching Tor nodes
