# Polyform IP Threat Intelligence

> Polyform IP Threat Intelligence is a paid API for AI agents from api.polyform.org, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-09).

Returns a malicious/safe verdict, 0-100 threat score, and source attribution for an IPv4 address by cross-referencing public abuse feeds (blocklist.de, Spamhaus DROP) and Polyform's own scanner traffic observations.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability polyform-ip-threat-intelligence-dc82c852
```

Example prompt: Can you check whether 45.134.26.5 is a hostile or malicious IP — I want to know its threat score and which abuse feeds have flagged it?

## When to prefer this

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.

## Known failure modes

- 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

## 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.
