# Dragons Eye Threat Indicator Lookup

> Dragons Eye Threat Indicator Lookup is a paid API for AI agents from api.ransomware-tracker.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-27).

Checks a single domain or IPv4 address against ThreatCluster's 30-day high-confidence IOC feed and returns a listed/not_listed verdict with match details, linked threat reports, and cluster context.

## 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 dragons-eye-threat-indicator-lookup-335eda14
```

Example prompt: Can you check whether the domain update-cdn77[.]net is listed as attacker infrastructure in the Dragons Eye ThreatCluster IOC feed and tell me the verdict, match type, and any linked threat reports?

## When to prefer this

Use this endpoint when you need a fast, per-indicator verdict against a curated, high-confidence IOC feed sourced from recent ransomware and threat reporting — especially when you want linked source reports and ThreatCluster cluster context alongside the verdict. Prefer this single-indicator endpoint for real-time alert triage or on-demand lookups; use the batch endpoint when checking 100+ indicators at once. Choose this over generic threat intel APIs when ransomware and attacker infrastructure coverage with sourced, explained matches is the priority.

## Known failure modes

- 503 returned when feed is stale (older than 3 hours) — call is not charged
- Invalid or too-short query string (fewer than 3 characters) rejected with 400
- Malformed IPv4 or domain format may return no matches rather than an error
- Not listed verdict does not guarantee the indicator is safe — absence of evidence is not evidence of absence
- Feed only covers a 30-day rolling window; older IOCs will not match

## How this service works

Dragons Eye Lookup: Domain or IPv4 threat-indicator check against ThreatCluster's 30-day high-confidence IOC feed. Is this domain (or a parent domain) or IPv4 address listed as attacker infrastructure in recent threat reporting? Returns verdict listed/not_listed, match type, the stated reason, linked reports and ThreatCluster clusters, and feed freshness. Served from a cache refreshed about hourly; if the feed is older than 3 hours the call returns 503 and is not charged. No match is not proof o

## Output

Returns a JSON object with: a verdict (listed or not_listed), the indicator type and value queried, match count, and an array of matches each containing match type (e.g. exact_domain, parent_domain), confidence, reason, linked source reports with publisher/title/URL, and associated ThreatCluster cluster URLs and IDs. Also includes feed metadata: when it was last refreshed, the time window (720 hours), total indicators in feed, and overall confidence level. Returns HTTP 503 (uncharged) if feed data is older than 3 hours.
