Clearbit killed their free tier in April 2025. Now it's "Breeze Intelligence" — $75/month minimum, HubSpot subscription required, credits expire monthly.
I needed company enrichment for a side project and didn't want to pay $0.10 per lookup. So I built my own.
What it does
Give it a domain → get back a full company profile. One API call, 7 data sources:
- DNS/MX records → email provider (Google Workspace, Microsoft 365, etc.)
- SSL certificate → organization name, issuer
- WHOIS → registrar, creation date, country
- HTML parsing → description, social links, emails, phones
- Tech stack detection → 30+ technologies (React, Shopify, Stripe, etc.)
- Schema.org → structured company data
- Reverse DNS → hosting provider (AWS, GCP, Cloudflare, etc.)
Example: enrich apple.com
const response = await fetch('https://web-intelligence-api.p.rapidapi.com/enrich', {
method: 'POST',
headers: {
'Content-Type': 'application/json',
'X-RapidAPI-Key': 'YOUR_KEY',
'X-RapidAPI-Host': 'web-intelligence-api.p.rapidapi.com'
},
body: JSON.stringify({ domain: 'apple.com' })
});
Returns:
- Company: Apple Inc. (from SSL cert)
- Email: Self-hosted (custom MX servers)
- Phone: 1-800-692-7753
- SSL issuer: Apple Inc. (self-signed)
- WHOIS: Created 1987, US, registrar COM LAUDE
- SPF: ✅ DMARC: ✅
- Social: YouTube, LinkedIn, Facebook, Twitter (from schema.org)
Pricing vs. Clearbit
| Company Intelligence API | Clearbit / Breeze | |
|---|---|---|
| Per enrichment | $0.005 | $0.09-$0.10 |
| Free tier | 50/day | None (removed 2025) |
| Requires HubSpot | No | Yes |
| Minimum cost | $0 | $75/mo + HubSpot |
Try it
Free tier: 50 calls/day, no credit card.
It also has /validate-email (DNS + disposable check) and /extract (raw URL scraping).
Built this as a solo dev. Feedback welcome.
