Domain Intelligence API endpoints
| Method | Endpoint | Description |
|---|---|---|
| lookup | ||
| GET |
Full Lookup /lookup/{domain} |
Returns DNS, WHOIS, SSL, subdomains, and email-security data in one concurrent response. Internal lookups run in parallel for maximum speed. Sub-second response on cache hits. |
| domain | ||
| GET |
DNS only /domain/{domain}/dns |
Low-level DNS resolution for A, AAAA, MX, NS, TXT, SOA, and CAA records. Uses an asynchronous resolver with a strict 5-second timeout. |
| GET |
Subdomains only /domain/{domain}/subdomains |
Subdomain discovery via concurrent multi-source aggregation (crt.sh, certspotter, hackertarget) with a DNS bruteforce fallback. Returns up to 1,000 results. |
| GET |
WHOIS only /domain/{domain}/whois |
Domain registration data retrieved via a highly resilient three-tier fallback chain: rdap.org → IANA bootstrap → legacy WHOIS port 43. |
| GET |
Email Security only /domain/{domain}/email-security |
Analyzes the domain's email authentication posture. Inspects DNS TXT records to determine SPF, DKIM, DMARC, MTA-STS, and BIMI configurations. |
| GET |
SSL only /domain/{domain}/ssl |
Performs a live TLS handshake to port 443 and parses the leaf certificate. Returns the issuer, validity window, SANs, signature algorithm, and key info. |
