Verified reference truth for AI agents

Facts your agents can cite.

One hosted knowledge base for global commerce — every country, trade location, carrier, goods classification and sanctioned party, each value traceable to its source, its ingest run, and its freshness.

§02

Every answer arrives with its citation.

Most databases store values. Scientia Basis stores claims about values — which dataset asserted it, the exact source, which ingest run produced it, and when it was last confirmed. Screening returns candidates, not verdicts. Every response identifies its engine and corpus release; available explanations depend on that engine.

The example below records historical Yente behavior, not current matching availability. Initial launch uses lexical screening against pinned snapshot 2026.10.2 while the stronger index is unaligned. Read the current screening limits.

§03

Three doors, one corpus.

An agent, a pipeline and a terminal get identical answers with identical provenance. There is no dashboard — the interface is whichever assistant you already use.
