isipsafe

Official Python client and command-line tool for isIPsafe, the free IP reputation and abuse reporting service.

• Check whether an IP address is malicious before you trust it
• Report attackers from your logs, one at a time or 10,000 at once
• Download the blocklist in a firewall-ready format (nftables, ipset, nginx, apache, MikroTik, STIX and more)

No dependencies outside the Python standard library. Python 3.9+.

pip install isipsafe

Get an API key

Lookups work without a key (400 per day per address). Reporting, bulk uploads and the blocklist need a free key from isipsafe.com/login. A key also raises the lookup limit to 10,000 per day.

export ISIPSAFE_API_KEY=sl_your_key_here

The client sends the key in an Authorization header, never in the URL, so it stays out of proxy and server logs.

Python

from isipsafe import Client

client = Client()  # reads ISIPSAFE_API_KEY, or pass Client("sl_...")

result = client.check("185.220.101.1")
print(result.abuse_confidence_score, result.total_reports, result.categories)

if result.is_malicious():  # score >= 75, has reports, not allowlisted
    block(result.ip_address)

client.report(
    "203.0.113.50",
    ["ssh", "brute-force"],
    comment="sshd: 212 failed logins in 10 minutes",
)

Report many addresses at once

result = client.bulk_report(
    [
        {"ip": "203.0.113.50", "categories": ["ssh", "brute-force"], "comment": "sshd"},
        {"ip": "198.51.100.4", "categories": "port-scan"},
    ]
)
print(result.saved_reports, result.invalid_reports)

Blocklist

ips = client.blocklist(confidence_minimum=90, except_countries=["GB"])
nft = client.blocklist_raw(format="nftables")

Everything else

Method	What it does
check(ip, max_age_in_days=None, verbose=False)	Score, report counts, location and network for one address
is_malicious(ip, threshold=75)	Shortcut that returns True or False
report(ip, categories, comment=None, timestamp=None)	Report an address or CIDR network
bulk_report(rows) / bulk_report_csv(text)	Up to 10,000 reports in one request
reports(ip, page=1, per_page=25)	Reports filed against an address, newest first
check_block(network)	Reported addresses inside a network (up to /16 or /48)
blocklist(...) / blocklist_raw(format=...)	The highest-confidence addresses
clear_address(ip)	Delete your own reports for an address
categories()	All report categories and their slugs

Errors

Every error inherits from isipsafe.IsIPsafeError.

Exception	When
AuthenticationError	Missing or wrong API key (401)
ValidationError	Invalid input, or an allowlisted address was reported (422)
RateLimitError	Too many requests (429); see .retry_after
APIError	Any other error status; see .status
NetworkError	The API could not be reached

Lookups are retried automatically on network errors and 5xx responses. Reporting the same address twice within 15 minutes is not an error: report() returns a result with duplicate=True.

Command line

$ isipsafe check 185.220.101.1
185.220.101.1  not flagged
  score       56/100 (Medium)
  reports     24 from 5 reporters
  categories  port-scan, hacking, vuln-scan, web-app-attack, c2
  network     DE AS60729 Stiftung Erneuerbare Freiheit
  flags       Tor exit
  details     https://isipsafe.com/ip/185.220.101.1

$ isipsafe report 203.0.113.50 -c ssh,brute-force -m "sshd: 212 failed logins"
$ isipsafe bulk-report reports.csv
$ isipsafe blocklist --format nftables --confidence-minimum 90 -o blocklist.nft
$ isipsafe check-block 185.220.101.0/24
$ isipsafe categories

Add --json to check, report, reports, check-block and categories for machine-readable output.

Use --fail-if-malicious in shell scripts. The command exits with status 1 when the address is malicious:

if ! isipsafe check "$IP" --fail-if-malicious --threshold 80 > /dev/null; then
    echo "blocking $IP"
fi

Exit codes: 0 success, 1 malicious (only with --fail-if-malicious), 2 error.

Categories

Use the slug or the numeric ID. Common ones: ssh, brute-force, port-scan, web-app-attack, sql-injection, vuln-scan, bad-bot, ddos, email-spam, phishing. Run isipsafe categories for the full list, or see isipsafe.com/categories.
