Bulk Domain Lookup — WHOIS/RDAP, Expiry, DNS

Check hundreds or thousands of domains at once: is it registered or available, who is the registrar, when was it created, when does it expire, which nameservers and mail servers does it use. $1 per 1,000 domains.

Uses RDAP — the official, machine-readable successor of WHOIS run by the registries themselves (located via IANA's bootstrap registry) — plus live DNS lookups.

What can it be used for?

• Domain portfolio monitoring: expiry dates and days until expiry for all your domains (run it on a schedule)
• Availability checks for name ideas (registered: false)
• Lead and market research: domain age, registrar, hosting / email provider (from NS and MX records)
• Security and brand protection: check look-alike domains, DNSSEC status
• Data cleaning: validate domains in a CRM or spreadsheet

Input

Field	Description
domains	Domains or URLs (https://www.example.com/page → example.com)
includeDns	A, AAAA, MX, NS records (default on)
includeTxt	TXT records such as SPF (default off)
maxConcurrency	Parallel lookups (each RDAP server is additionally rate-limited politely)

An unregistered domain returns "registered": false.

Coverage

RDAP covers all generic TLDs (.com, .net, .org, .dev, .app, .ai, .xyz, ...) and many country TLDs (.uk, .kr, .tw, ...). Some country TLDs (for example .jp, .de, .io, .co, .cn) have no public RDAP service: for those the result has "rdapAvailable": false and contains DNS information only (whether the domain resolves, its nameservers and mail servers). We do not scrape registry WHOIS servers whose terms forbid bulk use.

Privacy

Only the registrar is returned. Registrant and contact details (personal data) are intentionally not included, even when an RDAP server provides them.
