Domain Intelligence tools (6, 1 write)

write = sends, deletes, buys or posts
  • dns_recordsFree

    DNS records for a domain: A, AAAA, MX, TXT, NS, CAA and SOA, resolved in parallel.

  • domain_lookupFree

    Full report on a domain in one call: WHOIS/RDAP registration, DNS records, live SSL certificate, subdomains (live hosts with IPs first) and email authentication (SPF, DMARC, DKIM). Use it to triage a suspicious domain or profile a company's domain. If one section fails it comes back as an object with an `error` field and the rest is unaffected. Set wait=true to wait for every subdomain source (up to about 20 s) instead of the fast first result.

  • email_securitywrite actionFree

    Email authentication for a domain: SPF and DMARC records, and DKIM keys found by probing about 29 common selectors (Google, Microsoft 365, Mailchimp, SendGrid and others). Custom selectors may not be found.

  • ssl_certificateFree

    The certificate a domain serves on port 443, from a live TLS handshake: issuer, subject, valid_from, valid_to, days_until_expiry, SANs, signature algorithm and serial number.

  • subdomainsFree

    Subdomains of a domain from certificate transparency logs, passive DNS and DNS brute force. `live` lists hosts that resolve now, each with its IP; `subdomains` lists every name found, live first; `pools` summarises large shared-infrastructure zones. The first lookup of a domain is a fast snapshot and later ones are fuller; set wait=true to wait for every source (up to about 20 s).

  • whois_lookupFree

    Registration data for a domain: registrar, created, updated and expiry dates, nameservers and status. RDAP first (rdap.org, IANA bootstrap, 22 fallback servers), then port-43 WHOIS for 60+ TLDs. `_source` says which one answered. Use it for domain age, expiry or registrar checks.

Domain Intelligence API

WHOIS/RDAP, DNS, SSL/TLS, subdomains and email security (SPF, DMARC, DKIM) for any domain, in one REST call.

A FastAPI service that runs the five lookups in parallel and returns one JSON object. Built and run in production by Osiris Technical Institute.

  • Website and live demo:
  • Free web report for any domain: https://oti-labs.com/report/{domain}, e.g.
  • API key and pricing: RapidAPI listing
  • OpenAPI spec: rapidapi/openapi.json

Try it (no key needed)

The public demo returns the full aggregate result, limited to 5 requests per IP per day:

curl -s https://oti-labs.com/demo/example.com | jq

Use it (RapidAPI key)

curl -s "https://domain-intelligence-api.p.rapidapi.com/lookup/example.com" \
  -H "X-RapidAPI-Host: domain-intelligence-api.p.rapidapi.com" \
  -H "X-RapidAPI-Key: YOUR_RAPIDAPI_KEY"
import requests

r = requests.get(
    "https://domain-intelligence-api.p.rapidapi.com/lookup/example.com",
    headers={
        "X-RapidAPI-Host": "domain-intelligence-api.p.rapidapi.com",
        "X-RapidAPI-Key": "YOUR_RAPIDAPI_KEY",
    },
    timeout=30,
)
data = r.json()
print(data["whois"]["registrar"], data["ssl"]["days_until_expiry"], data["subdomains"]["count"])
// Node 18+ (built-in fetch)
const res = await fetch("https://domain-intelligence-api.p.rapidapi.com/lookup/example.com", {
  headers: {
    "X-RapidAPI-Host": "domain-intelligence-api.p.rapidapi.com",
    "X-RapidAPI-Key": "YOUR_RAPIDAPI_KEY",
  },
});
const data = await res.json();

MCP server

AI agents and assistants can use the API as tools through the hosted MCP server at https://oti-labs.com/mcp (Streamable HTTP, registry name com.oti-labs/domain-intelligence). No key is needed for the first 1,000 lookups a month per IP. After that, send a RapidAPI key in the X-RapidAPI-Key header; its free plan adds 1,000 a month.

claude mcp add --transport http domain-intelligence https://oti-labs.com/mcp

Tools: domainlookup, whoislookup, dnsrecords, sslcertificate, subdomains, email_security. Setup for Cursor, VS Code, Windsurf and Claude Desktop is in mcp/README.md.
