Domain Intelligence: WHOIS/RDAP, DNS, MX, SPF, DMARC & SSL Checker

One row per domain with registrar, creation/expiry date and domain age (RDAP), A/AAAA/NS/MX/TXT records, email provider detection, SPF & DMARC policy, and SSL issuer/expiry. Bulk, fast, no API keys.

Why this actor

• Everything in one row (WHOIS + DNS + email security + SSL) that competitors split across 3–4 actors; email-provider detection for B2B segmentation.
• Pay only for results: $2.50 per 1,000 domain checkeds, no start fee, failed lookups are free.
• Robust: automatic retries with exponential backoff, respects Retry-After, per-item error rows instead of crashed runs.
• Clean, flat JSON/CSV/Excel output ready for Google Sheets, Make, Zapier, n8n, Clay, or the Apify API.

Use cases

• Lead enrichment: is the prospect on Google Workspace or Microsoft 365?
• Email deliverability audits (SPF/DMARC) for agencies
• SSL / domain expiry monitoring for portfolios
• Fraud & trust checks via domain age

How to use Domain Intelligence Checker

1. Enter domains (e.g. apify.com, github.com). URLs are fine too; the domain is extracted.
2. Toggle SSL and WHOIS checks if you only need DNS.
3. Click Start and get one row per domain, ready for CSV, Excel or your CRM.

Comparison: Domain Intelligence Checker vs alternatives

	This actor	Typical alternatives
Checks per row	WHOIS/RDAP + DNS + MX + SPF + DMARC + SSL	Usually one check per tool
API keys	None	WHOIS APIs need paid keys
Bulk	Thousands per run	Web tools: one at a time
Pricing	$2.50 / 1,000 domains	Per-lookup credits or subscription

Pricing

Pay-per-event: $0.0025 per domain checked (= $2.50 / 1,000). Use Max results to cap spend. Apify's free plan credit covers thousands of results per month.

Agents can also call it directly via the Apify API (POST https://api.apify.com/v2/acts/shawndunn~domain-intelligence-whois-dns-ssl/run-sync-get-dataset-items) and pay per result, with no subscription.

FAQ

Is it legal? The actor only reads publicly available data from public endpoints, without logins, and does not bypass paywalls or access controls. You are responsible for using the data in line with applicable laws (e.g. GDPR) and the source sites' terms.

Something broke? Open an issue in the Issues tab; we typically respond within 24 hours and ship fixes fast.

How do I check domain expiry dates in bulk? Paste your domain list; registrar, createdAt and expiresAt come from RDAP, the modern replacement for WHOIS.

Can I see which email provider a company uses? Yes. MX records are mapped to providers such as Google Workspace or Microsoft 365, which is useful for sales targeting and deliverability audits.

Can I monitor SSL certificate expiry? Schedule the actor weekly and alert on sslDaysLeft via a webhook or Slack integration.
