Every U.S. International Trade Commission investigation — 4,386 cases (1930-2026): 1,917 antidumping/countervailing-duty (AD/CVD) investigations into goods dumped or subsidized by foreign governments, 1,665 Section 337 unfair-import (patent/IP infringement) cases, plus factfinding studies. 1,359 currently active. Per case: investigation number, AD/CVD vs Section-337 class, title, product, phase, petition-received/start/end dates, active status, and the canonical USITC case-record link. The trade-enforcement vertical (companies/countries/products fighting over unfair imports) — joins the entity/screening layer by product/title. Powers /trade-case/{id} canonical pages + /api/v1/itc/{search,list}. Key-free from the USITC Investigations Database System. (Participant/law-firm layer pending — the USITC participant API is currently maintenance-gated.)
