B2B Domain Contact, MX Email Provider & Tech Stack Enricher (MCP Ready)

Fast, deterministic B2B company domain enrichment built for AI Agents (Model Context Protocol / Apify Standby Mode), Outbound Sales / RevOps teams, and Market Intelligence pipelines.

Given a list of company domains (e.g., apify.com, stripe.com), this Actor resolves live website metadata, business email addresses, social media links, DNS MX email infrastructure, and web technology signals in < 1.5 seconds per domain without browser overhead.

Use Cases

• Outbound Sales & SDR Enrichment: Turn raw company domain lists into actionable contact records with verified social profiles (LinkedIn, X/Twitter, GitHub) and role/business emails.
• Email Deliverability Segmentation: Detect whether a prospect uses Google Workspace, Microsoft 365, Proofpoint, Mimecast, Zoho, or Proton Mail via live DNS MX inspection so you can route outbound campaigns by mail server type.
• Technographic Qualification: Identify companies running Next.js, Shopify, WordPress, HubSpot, Stripe, or Cloudflare before reaching out.
• AI Agent Tool Calling (/mcp): Expose instant domain intelligence to Claude, Cursor, LangGraph, or custom MCP agents via Apify Standby Mode.

Pricing (Pay-Per-Event)

This Actor uses transparent Pay-Per-Event (PPE) pricing enforced by @fleet/ppe-guard:

Event Name	Price (USD)	When is it charged?
apify-actor-start	$0.00005	Once when the Actor starts after input validation passes.
result-item	$0.00200	Per schema-validated company domain profile pushed to the dataset ($2.00 per 1,000 domains).

• Budget Ceiling Protection: Respects ACTOR_MAX_TOTAL_CHARGE_USD and automatically self-throttles at 95% of your budget ceiling so runs finish cleanly without mid-item data truncation.
• Restart Idempotency: Persists charged domain keys in CHARGE_LEDGER_V1 so container migrations never double-charge the same domain.

---

Standby MCP & AI Agent Integration

This Actor supports Apify Standby Mode (webServerMcpPath: "/mcp"). Connect any MCP client (Claude Desktop, Cursor, or mcp.apify.com) to invoke the enrich_company_domains tool with zero container cold-start latency.

Data Privacy & Responsible Use

• Public Business Data Only: This Actor inspects publicly accessible company homepages and public DNS MX records. It does not bypass authentication, scrape private social profiles, or store extracted data outside your Apify run dataset.
• Compliance: Users are responsible for complying with applicable regulations (such as GDPR, CCPA, and CAN-SPAM) when contacting business addresses obtained from public company websites.

FAQ & Support

• Why did a domain return empty emails? Many enterprise homepages do not list raw mailto: addresses on their root page. Chain this Actor with b2b-company-lead-finder to infer {first}.{last}@domain patterns and permute executive emails backed by MX verification.
• Support & Issues: Please open a ticket in the Issues tab on the Apify Store page with your Run ID for fast assistance.
