After installing, just ask your agent naturally:
- "Look up the DNS records for github.com" — runs A record query via Google DNS
- "Check the SSL certificate for stripe.com" — inspects cert chain, expiry, TLS version
- "Who owns openai.com?" — WHOIS lookup with registrar, dates, nameservers
- "Run a full health check on my-domain.com" — 11 parallel checks, overall score out of 100
- "Check if 203.0.113.1 is blacklisted" — queries 47 DNSBL engines + AbuseIPDB
- "Find all subdomains of example.com" — CT log discovery with DNS resolution
- "Does google.com have SPF, DKIM, and DMARC configured?" — runs all three email auth checks
- "Test SMTP connectivity to smtp.office365.com on port 587" — checks TLS, capabilities

All API endpoints are free and require no authentication. The base URL is https://dnsrobot.net. Endpoints accept JSON request bodies and return JSON responses. Three endpoints (subdomain_finder, ip_blacklist, port_check with multiple ports) stream results as NDJSON (newline-delimited JSON).
For full endpoint documentation with parameters and response schemas, see the SKILL.md file.
