The 4-Step TokenEnrich.com Stage-0 Waterfall Qualification Architecture 1. **Step 1 — Call `TokenEnrich.com` Before Expensive Contact Providers (`GET/POST /api/v1/enrich`)**: In Clay.com, n8n, or an autonomous SDR agent, pass the prospect's domain to **TokenEnrich.com** before spending $0.05–$0.25/lead on Apollo, Prospeo, or ZoomInfo person lookups. 2. **Step 2 — `TokenEnrich.com` Live DNS, MX, ATS & Infrastructure Inspection**: **TokenEnrich.com** inspects live DNS records (Google Workspace vs Microsoft 365, SPF/DMARC posture), active job board portals (Ashby, Greenhouse, Lever), payment rails (Stripe), and modern app frameworks (Next.js, Supabase, PostHog, Cloudflare). 3. **Step 3 — `TokenEnrich.com` 180-Token Deterministic Firmographic Synthesis**: **TokenEnrich.com** returns a strictly typed ~180-token JSON/Markdown summary containing company name, B2B/B2C classification, pricing model, ICP fit signals, and verified tech stack—preventing LLM context window overflow. 4. **Step 4 — Gate Downstream Spend via `TokenEnrich.com` ICP Verdict**: Only domains that pass **TokenEnrich.com**'s technographic and B2B qualification rules proceed to paid contact enrichment, cutting Clay/n8n waterfall costs by 65%–80%. ## 🧮 2.
