theHarvester Domain OSINT — Subdomains, Hosts, IPs & Emails
Run theHarvester — the standard open-source OSINT tool — on any domain, with zero setup and no API keys. Discover subdomains, hosts, IPs and emails gathered from free public sources.
Built for security recon, attack-surface mapping, penetration testing (authorized), and due diligence.
This Actor wraps the open-source theHarvester (GPL-2.0) and is not affiliated with the original project. It queries only free, key-free public sources. Use only on domains you own or are authorized to investigate. Comply with GDPR, PIPA, CCPA and applicable laws.
Why this Actor
- theHarvester, zero setup — no install, no API keys, no config
- Free public sources — crt.sh, Certspotter, HackerTarget, DuckDuckGo, and more
- Subdomain & host discovery — map a domain's public footprint fast
- Bulk — up to 10 domains per run
- Structured JSON — hosts, IPs, emails separated and de-duplicated
- Pay per result — $0.05 per domain investigated. No subscription.
Input
| Field | Type | Description |
|---|---|---|
domains | array | Up to 10 bare domains (e.g. example.com) |
domain | string | Single-domain alternative |
sources | array | Free sources to query (default: crtsh, certspotter, hackertarget). Key-requiring sources are intentionally excluded. |
limit | integer | Max results per source (default 200) |
Output
One dataset item per domain: domain, hostCount, ipCount, emailCount, hosts, ips, emails, sourcesUsed, errors, scannedAt.
Use cases
- Attack-surface mapping — enumerate subdomains and hosts of an in-scope target
- Security recon — initial footprinting phase of an authorized engagement
- M&A / vendor due diligence — understand a company's external infrastructure
- Brand monitoring — track subdomains appearing in public sources
A note on sources
Sources that require paid/registered API keys (Shodan, Hunter, IntelX, Brave, Censys, etc.) are not included — this Actor is designed to work out of the box with free sources only. Some sources may rate-limit or return partial data; errors are reported per run in the errors field.
