Sources & cost basis
The honest catalog of paid and free enrichment sources — what each gives, what it costs, its lawful basis — and where the synthesized data lives. · 4 min read
The enrichment catalog (pipeline/enrichment/catalog.py) is reference data that lists every source we could enrich with, paid or free, and is honest about cost and the lawful-basis question per source. It is grouped into three stages of the touchpoint flow: free / low-cost, paid append, and engagement.
Free / low-cost
| Email domain parse | $0 · user-provided (low risk) · instant |
| DNS / MX / WHOIS | $0 · public record · days |
| News / RSS / Google News | $0 · public, attribute the source · hours |
| SEC EDGAR, GitHub, LinkedIn public, BuiltWith | $0 / free tier · public or ToS-restricted · cataloged |
Paid append
| Clearbit / HubSpot Enrichment | per-enrichment / seat · vendor AUP + your basis |
| ZoomInfo, Apollo.io, People Data Labs | seat + credits · strict AUP, record basis |
| 6sense / Demandbase, Bombora | platform / subscription · account-level, lower PII risk |
Engagement
| Email open pixel | $0 · disclose tracking; some clients block it |
| Click tracking (wrapped links) | $0 · first-party, low risk |
| First-party site analytics | $0 · first-party cookie + notice |
| Reverse-IP (Clearbit Reveal / KickFire) | per-lookup · account-level, no PII |
Each row carries a used_in_demo flag and a live flag. In the demo, sources are simulated unless marked live; the one genuinely live source is the news RSS. Nothing in the catalog calls a paid API — the paid rows are documented, not invoked.
Where the data lives
| provenance.sqlite | recipients · form_events · cta_events · verdict_cache · llm_cache |
| profiles.sqlite | synthesized profiles + every fact receipt (source · basis · verdict) |
| claims/library.json | the versioned claim-evidence graph |
| observe/*.jsonl | append-only observability event ledger (one per lane) |
| helix_tenant.yaml | human-owned claim policy + enrichment-source policy |
