Domain Intel: Tech Stack, Email Provider & Domain Age

Give it a list of company domains and get, for each one:

• Tech stack detected on the homepage: CMS and site builders (WordPress, Webflow, Wix, Shopify, VTEX, Nuvemshop...), frameworks (Next.js, Nuxt...), hosting and CDN (Cloudflare, Vercel, Netlify, CloudFront...), analytics, marketing automation (HubSpot, RD Station, Klaviyo...), live chat, payments (Stripe, Mercado Pago, PayPal...) and cookie consent.
• Email provider from MX records (Google Workspace, Microsoft 365, Zoho, Proofpoint, Locaweb...), plus whether SPF and DMARC are set and the DMARC policy.
• Domain age: registration and expiry dates and the registrar, from RDAP.
• Website basics: final URL after redirects, title, description, language and social profile links.

No personal data is collected: only public DNS, RDAP and the public homepage.

Use cases

• Qualify B2B leads by technology ("all Shopify stores using Klaviyo").
• Find companies on Google Workspace vs Microsoft 365 before an email or IT pitch.
• Check email-security posture (SPF/DMARC) across a list of prospects.
• Filter out very young domains in fraud or partner checks.
• Give AI agents a cheap, structured "what is this company's website built on?" lookup.

Input

{ "domains": ["shopify.com", "stripe.com", "nubank.com.br"] }

URLs are accepted too (https://www.example.com/page becomes example.com). Duplicates and invalid entries are skipped. Up to 10,000 domains per run.

Output (one item per domain)

{
  "domain": "shopify.com",
  "website": { "reachable": true, "finalUrl": "https://www.shopify.com/", "status": 200, "title": "Shopify", "language": "en" },
  "technologies": [{ "name": "Shopify", "category": "E-commerce" }, { "name": "Cloudflare", "category": "CDN" }],
  "email": { "provider": "Google Workspace", "mx": ["aspmx.l.google.com"], "spf": true, "dmarc": true, "dmarcPolicy": "reject" },
  "registration": { "createdAt": "2005-03-11T05:18:03Z", "expiresAt": "2027-03-11T05:18:03Z", "ageYears": 21.5, "registrar": "MarkMonitor Inc." },
  "errors": []
}

errors lists any part that could not be checked (for example a site that times out); the other parts are still returned.

Pricing

Pay per event: you are charged only for domains where something was found. Domains that do not exist or cannot be reached at all are returned free of charge.

Limits

• Detection reads the first 128 KB of the homepage, so tools loaded only at the very bottom of large pages may be missed.
• Sites that block bots may show as unreachable; email and registration data are still returned.
