Domain WHOIS and DNS Lookup: Bulk Domain Intelligence, $1 per 1,000 Domains

Enrich any domain with WHOIS records, full DNS, and email-deliverability posture. Returns registrar, registrant org, creation date, expiry, name servers, A / AAAA / MX / TXT / NS / CNAME records, SPF / DMARC / DKIM status, and the inferred email provider (Google Workspace, Microsoft 365, Zoho, custom). Built for bulk: pass 10,000 domains and it returns one row per domain. Ideal for B2B prospecting, security audits, M&A research, and email-deliverability cleanup.

What you get

• WHOIS: registrar, registrant_org, creation_date, expiry_date, updated_at, registrant_country, status_codes[]
• DNS A/AAAA: ipv4_addresses[], ipv6_addresses[], cname_target
• Mail records: mx_records[], primary_mx, email_provider (Google, Microsoft 365, Zoho)
• Security records: spf_record, has_spf, dmarc_record, dmarc_policy, dkim_selectors[]
• Other DNS: ns_records[], txt_records[], soa_record, has_dnssec

Primary use cases

• B2B prospecting. Enrich 50,000 leads with email provider, registrar age, and parent organization
• Security audits. Identify domains with weak or missing SPF / DMARC across a portfolio
• M&A research. Inventory the full domain estate of a target company including aliases and ccTLDs
• Email-deliverability cleanup. Verify sender domains have SPF + DMARC + DKIM before outbound campaigns
• Brand monitoring. Track lookalike domain registrations and their hosting infrastructure
