An n8n lead enrichment workflow you can import in one click
The CyberMax Developer Kit is a free, MIT-licensed set of files that plugs CyberMax tools into n8n, Zapier, Make, Postman and MCP clients. Its chained n8n recipe enriches a domain list in two steps: Hollerdex finds each site's public contact details (role emails, phones, social profiles, contact page) and DomainDNA adds the tech stack, WHOIS and domain age, then n8n merges them per domain. Import the JSON, add your Apify token, run. You pay only per result found.
Hollerdex output for two domains (public contact details only)
| Domain | Primary email | Email type | Socials found | Contact page | Pages checked |
|---|---|---|---|---|---|
| apify.com | hello@apify.com | role | linkedin, x, tiktok, github, discord | apify.com/contact | 5 |
| airtable.com | privacy@airtable.com | role (legal) | linkedin, x, facebook, instagram, youtube | airtable.com/contact-sales | 6 |

Why teams pick CyberMax Developer Kit
- Import and run: ready n8n workflows for every CyberMax tool plus two chained recipes, an OpenAPI 3.1 file and a Postman collection.
- Pay per result, no subscription: domains with no contacts, blocked sites and failures are free.
- Only public business contact details from the company's own site, each with the page it was found on.
- The same tools work as MCP servers in Claude Desktop, Claude Code, Cursor and VS Code with the configs in the kit.

- Replace YOUR_APIFY_TOKEN in the two HTTP Request nodes with your Apify API token.

FAQ
Why not Clay?
Clay is a full enrichment workspace with many data providers, from $167/month. If you already run n8n and only need public contacts and tech stack per domain, this workflow costs $0.004 per domain found, with no subscription.
Why not Hunter?
Hunter finds and verifies people's email addresses from $49/month. Hollerdex returns the public business contacts a site publishes itself (role emails, phones, socials, contact forms), billed per result.
Does it find personal emails?
Only what the company publishes on its own site; it does not guess or build email patterns.
Do I need Apify?
Yes. The tools run as Apify Actors on your own Apify account, which bills per result; the kit itself is free.
Can I cap spending?
Yes: add maxTotalChargeUsd to the call, for example &maxTotalChargeUsd=0.50.
