How this service works
Is this IP hostile? Reputation verdict for an IPv4 from public abuse feeds (blocklist.de, Spamhaus DROP) plus Polyform's own observed scanner traffic. Returns malicious flag, 0-100 score, and which sources flagged it. For bot filtering, fraud and firewall automation. JSON.
Output
A JSON object containing the queried IP, a boolean malicious flag, a 0-100 numeric threat score (higher = more dangerous), an array of source names that flagged the IP (e.g. 'blocklist.de', 'spamhaus-drop', 'polyform-observed'), and a boolean observedByPolyform indicating whether Polyform's own scanner traffic data contributed to the verdict.
Example use cases
Firewall rule automation from live traffic
“I'm seeing a lot of requests from 91.108.4.200 hitting my API — can you check if it's a known malicious or scanner IP and tell me its threat score and which blocklists it appears on?”
Fraud detection on new user signup
“A new account just signed up from IP 185.220.101.47 — is that a malicious or abusive IP I should block? Give me the reputation score and sources that flagged it.”
Bot filtering for ad click validation
“I need to verify whether the IP 5.188.10.76 that clicked our ad is a known bot or scanner — check its reputation and tell me if it's flagged by blocklist.de or Spamhaus.”
Technical details
Endpoint
GEThttps://api.polyform.org/v1/threat/ip?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, per-IP reputation verdict that combines multiple authoritative public abuse feeds (blocklist.de, Spamhaus DROP) with Polyform's proprietary scanner observations into a single scored response — especially useful for real-time bot filtering, fraud gating, or firewall automation where you want source attribution alongside the verdict. Prefer it over raw DNSBL lookups when you want a unified numeric score and JSON output without managing multiple feed queries yourself.
Side effects
- Invalid or non-IPv4 address input returns an error
- Private/reserved IP ranges may return no data or a clean verdict
- IP not found in any feed returns malicious:false with score near 0
- Payment failure (x402) results in 402 response before data is returned
- Rate limiting or network timeout may occur under high request volume
