B2B Domain Contact, Email Gateway, DNS SaaS & Tech-Stack Enricher (MCP-Ready)

Replace 3 separate outbound enrichment tools with a single zero-browser, sub-second B2B Domain Intelligence API built for Clay.com, Instantly, Smartlead, n8n, and MCP AI Agents.

For every company domain, this Actor extracts:

1. Cold-Email Gateway & Deliverability (DNS MX / SPF / DMARC): Identifies Google Workspace vs Microsoft 365 vs Proofpoint / Mimecast enterprise security gateways so cold-email agencies can segment sending inboxes and protect deliverability.
2. Hidden Enterprise SaaS Stack via DNS TXT Fingerprints: Uncovers internal B2B tools verified in root DNS TXT records even when invisible on the website (OpenAI Enterprise / ChatGPT, Anthropic / Claude, Atlassian Cloud, Slack Enterprise, HubSpot, Stripe, Linear, Notion, Miro, DocuSign, OneTrust, Salesforce, Klaviyo, etc.).
3. Verified Website Contacts & Social Profiles: Crawls the homepage and discovered /contact, /about, and /impressum subpages to extract clean business emails and company social links (LinkedIn, X/Twitter, GitHub, YouTube, Instagram, Facebook).
4. Active Ad Pixels, Web Tech Stack & Funnel Signals: Detects Meta Pixel, Google Ads Tag, LinkedIn Insight Tag, TikTok Pixel, GTM, GA4, HubSpot, Intercom, Stripe, Shopify, Webflow, Next.js, plus self-serve /pricing, /docs, and /careers ATS links.
