Can AI Handle KYC? Grounding LLMs For Due Diligence Tools
Short summary
LLMs can scaffold a KYC dashboard quickly but hallucinate when asked to verify whether a domain is legitimate or sanctioned. The article argues that reliable compliance tools must ground LLM answers in real data—WHOIS, IP geolocation, company registries, sanctions lists—and demonstrates the Portfolio Investigate API as an evidence layer. A Python example shows fetching a domain dossier and querying it via an LLM Ask endpoint, though the post doubles as promotion for that specific API.
- •LLMs reason over tokens not truth, causing stale knowledge, fabricated citations, and missing signals in KYC contexts
- •Grounding LLMs with structured evidence packets (WHOIS, IP geo, sanctions checks) constrains hallucination risk
- •Portfolio Investigate API aggregates five data sources into a single dossier with an LLM Ask endpoint for grounded follow-up questions
