How this service works
Domain Intelligence: RDAP/WHOIS, DNS, identity and DomainSure reputation
Output
Returns a structured JSON object with a top-level status and individual sub-objects for registration (WHOIS/RDAP ownership and dates), dns (DNS records and attributes), identity (identity-related signals), and reputation (DomainSure listing status and risk signals). Also includes the queried domain, query timestamp, product version, and price paid ($0.01 USD).
Example use cases
Phishing domain investigation
“I got a suspicious email from someone at secure-paypal-login.com — can you check if that domain is flagged for phishing or has any bad reputation signals, and also pull its registration and DNS info?”
Vendor domain due diligence
“Before we onboard a new supplier, can you run a full domain intelligence check on acmecorpsupplies.net — I want registration history, DNS setup, identity signals, and any reputation issues?”
Brand protection monitoring
“Someone might be typosquatting our brand — can you look up the domain intelligence for mybrandz.com, including who registered it, what DNS it's pointing to, and whether it's been flagged anywhere?”
Technical details
Endpoint
GEThttps://app.domainhelp.com/api/v1/domain/:domain?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a one-stop, structured domain intelligence lookup combining WHOIS/RDAP, DNS, identity, and reputation data in a single call. It is ideal for cybersecurity workflows (phishing detection, suspicious domain triage), vendor due diligence, brand protection, or any scenario where you need to understand the full profile of a domain. It supports batch lookups of up to 100 domains per call and allows selective component inclusion. Prefer this over separate WHOIS-only or DNS-only tools when you need correlated multi-signal intelligence at low cost ($0.01/call).
Side effects
- Domain not found or unresolvable — status returns 'unavailable'
- Timeout querying upstream RDAP/DNS sources — status returns 'timeout'
- Partial data returned when some components succeed but others fail — status returns 'partial'
- Invalid domain format (too short, too long, malformed) — validation error
- Rate limiting or payment failure for x402 micropayment — HTTP 402 or 429
- Unsupported TLD or registry — status returns 'unsupported'
