Shodan API
Search engine for internet-connected devices, providing data on open ports, running services, software versions, vulnerabilities (CVEs), and geolocation for any IP or domain.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Single API key passed as query parameter — less secure than header-based auth (key appears in server logs and URL history). No scope granularity. TLS enforced. Python SDK is well-maintained. Data access is powerful; key exposure could enable significant reconnaissance.
⚡ Reliability
Best When
A security agent needs to enumerate internet-facing assets, enrich IP intelligence, or identify exposed vulnerabilities without active scanning.
Avoid When
You need real-time scan results or internal network visibility.
Use Cases
- • Attack surface discovery for an organization's internet-facing assets
- • Identifying vulnerable or misconfigured devices exposed to the internet
- • Enriching IP addresses with service/banner/vulnerability data in security workflows
- • Hunting for specific software versions or services across the internet
- • Monitoring for unauthorized exposure of internal services
Not For
- • Real-time network scanning (Shodan is a crawl-based snapshot, not live)
- • Internal network scanning (only covers internet-facing assets)
- • Passive DNS or domain reputation lookups (use other tools)
- • Teams without security context — data is sensitive and powerful
Interface
Authentication
Single API key passed as query parameter (?key=) or via SDK initialization. No scopes — key has access to all endpoints the account tier supports.
Pricing
Free tier is quite limited for agent use. The 'Membership' plan unlocks more results but API credits are still capped. Production API use requires the higher tier.
Agent Metadata
Known Gotchas
- ⚠ Query credits are consumed even for empty results — agents can burn credits on bad queries
- ⚠ Data is not real-time — banners may be days to weeks old
- ⚠ Free tier returns maximum 1 result per query — agents need paid tier for useful results
- ⚠ Facet queries and filters have non-obvious syntax that agents often get wrong
- ⚠ Scan API requires separate on-demand credits beyond subscription
- ⚠ Some search filters require Membership or higher — error messages don't always clarify which tier is needed
