How this service works
Domain lookup in one call: DNS records (A, AAAA, MX, TXT, NS, CNAME, SOA, CAA with TTLs), registry RDAP registration data (registrar, created, updated and expiry dates, status, nameservers, DNSSEC) and the TLS certificate (issuer, names, validity, days left, chain verified). Use to check a domain before linking to, buying or trusting it. No registrant contact data. Typical response 1 to 2 s. Failed calls are not charged.
Output
Returns a structured JSON object with up to three sections depending on which parts were requested: (1) DNS section with each requested record type (A, AAAA, MX, TXT, NS, CNAME, SOA, CAA) and their TTLs; (2) registration section with RDAP data including registrar name, creation date, last updated date, expiry date, domain status flags, nameservers, and DNSSEC status; (3) TLS section with certificate issuer, covered names (SANs), validity start/end dates, days remaining, and chain verification result. No registrant contact (WHOIS privacy) data is returned.
Example use cases
Pre-purchase domain due diligence
“Before I buy the domain acmecorp.io, can you check its full registration history, when it expires, who the registrar is, and whether its DNS and TLS are clean?”
Suspicious link safety check
“I got an email with a link to secure-payments-verify.com — can you look up that domain's DNS records, registration details, and TLS certificate to help me figure out if it's legit or a phishing site?”
Email deliverability DNS audit
“Can you pull the DNS records for mybusiness.com — especially the MX, TXT, and SPF records — and also check whether the domain's TLS certificate is valid and how many days it has left?”

Endpoint
POSThttps://quantagentshop.com/v1/domain-lookup?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a comprehensive, single-call domain intelligence report combining DNS, RDAP registration, and TLS certificate data — instead of making separate DNS, WHOIS, and certificate queries. It is ideal for domain vetting workflows, pre-purchase due diligence, phishing/spam domain investigation, and infrastructure audits. Failed calls are not billed, making it low-risk for exploratory checks. Prefer this over manual DNS tools or separate WHOIS lookups when speed and consolidation matter.
Side effects
- Domain does not exist or is not resolvable — DNS section may return empty or NXDOMAIN
- RDAP data unavailable for certain TLDs — registration section may be null or partial
- Domain has no TLS certificate — TLS section returns null or error flag
- Malformed domain name input — API returns validation error
- Upstream DNS or RDAP timeout — call fails and is not charged
- Rate limits exceeded — HTTP 429 response
