Company Enrichment API: Domain to Buyer Fit Brief

Turn any domain into a buyer brief you can actually send. Get company data, tech stack, contact info, WHOIS, DNS, SEO metadata, social profiles, and an optional Buyer Fit Brief with a fit score, sales angle, buying signals, and risks. Built for SDRs, lead ops, agencies, and enrichment workflows that need a practical Clearbit, BuiltWith, Clay, or ZoomInfo alternative without a monthly contract.

Live Store proof as of 2026-06-17: 96 total users, 5,600 total runs, 31 users in the last 30 days, and 97%+ recent public-run success.

What makes this different

Most enrichment APIs hand you a JSON blob. You still have to read it, interpret it, and write the outreach yourself. This one does the reading for you.

Flip brief=true on any call and the response includes a structured artifact you can drop straight into a sales tool:

"buyer_brief": {
  "fit_score": 82,
  "fit_tier": "hot",
  "buyer_type": "midmarket",
  "sales_angle": "Open with their new Next.js migration. They're hiring 3 senior engineers per their careers page.",
  "buying_signals": [
    "modern stack: React, Next.js, AWS",
    "active hiring signals",
    "public decision maker contacts available"
  ],
  "risks": ["domain is under 12 months old"]
}

Raw data you always get

• Company identification (name, description, logo, favicon)
• Technology detection (35+ signals: CMS, frameworks, analytics, infrastructure, payments)
• Social profiles (X, LinkedIn, Facebook, Instagram, YouTube, GitHub, TikTok, Threads)
• Contact extraction (emails and phones found on the site)
• WHOIS data (domain age, registrar, creation and expiry dates)
• DNS analysis (A, MX, SPF, DMARC)
• SSL detection
• SEO metadata (title, description, OG image, canonical, H1 headings)
• Email provider detection (Google Workspace, Microsoft 365, Zoho, Proton)
• Bulk mode (up to 10 domains per request)
• Instant API via Standby mode

Use cases

• Sales prospecting. Replace your SDR's "research the company" step with a brief that names the angle.
• Lead scoring. Feed fit_score straight into your CRM as a numeric field.
• Agency outreach. Qualify 1,000 domains overnight and sort by fit_tier.
• CRM enrichment. Populate Salesforce and HubSpot with the structured fields.
• Due diligence. Get a one paragraph summary before a discovery call.
• Competitive mapping. Scan competitor stacks and social presence.
• Clearbit alternative. Enrich domains without needing a separate SaaS subscription.
• BuiltWith alternative for lightweight stack detection plus contact/social context.
• Clay workflow step. Use Apify API output as a lower-cost enrichment source before expensive human or AI research.

Pricing

Per event pricing. You only pay for what you run.

Mode	Events	Cost at current $0.005/event
Raw enrichment	1 event	$0.005 per domain
Enrichment + Buyer Fit Brief	3 events	$0.015 per domain

Bulk requests charge per domain. Health-check/example domains are guarded in the actor so repeated uptime pings do not burn paid enrichment work.

Apify competitor demand signal

Live Apify Store search on 2026-06-17 shows buyer demand around company enrichment, lead enrichment, and Clearbit alternatives. The strongest Store language clusters around "Apollo alternative", "ZoomInfo alternative", "lead enrichment", "domain enricher", and "Clearbit alternative".

Actor	30-day users	Total users	Positioning
code_crafter/leads-finder	3,833	38,720	Apollo/ZoomInfo-style leads with emails
logical_vivacity/scout	46	110	Lead enrichment + OSINT, domain/person dossiers
inexhaustible_glass/linkedin-email-finder	37	109	Email finder plus B2B lead enrichment
chieftools/b2b-linkedin-lead-generator	30	277	AI matching companies and decision-makers
foxlabs/company-enrichment	12	16	Firmographics, revenue, HQ, Clearbit-style enrichment
george.the.developer/company-enrichment-api	31	96	Domain to company data plus Buyer Fit Brief

The opportunity is to own the narrower "domain to buyer fit brief" lane instead of competing as another generic lead scraper.

How the brief works

The brief combines the raw enrichment signals (tech stack, contact availability, social footprint, domain age, positioning) and produces a scored artifact per domain. Score weighting favors reachable buyers with public decision maker contacts and a modern stack.

The brief now goes through a structured VPS endpoint instead of posting raw prompts straight to Ollama. The API returns a deterministic heuristic brief immediately, then the VPS warms an AI-enhanced brief in the background and serves that richer version from cache on later lookups for the same company summary. If the model is slow or unavailable, the request still fails open to the heuristic brief instead of sitting on a long timeout.
