Federal Laboratory Consortium for Technology Transfer

FLC Greenbook API

Public API behind the FLC Green Book mobile app. One published operation performs retrieval-augmented search over the sections of the Green Book (Federal Technology Transfer Legislation and Policy): semantic retrieval, LLM rerank, then a generated answer with the source sections that produced it. Gated by an app-key header issued for the mobile app.
